Normally Closed vs Normally Open Switch: What Are Differences?

发表于17 1 月, 2025由Love Dome

Switches are an essential part of everyday life. Whether you’re turning on a light, starting an appliance, or operating a piece of machinery, switches play a crucial role. Among the many types of switches available, normally closed (NC) and normally open (NO) switches are two of the most commonly used. Understanding their differences and functionality can help you choose the right type for your projects or applications.

In this blog, we’ll explain what these two switches are, how they work, and highlight the differences between them.

What Does a Normally Closed Switch Mean?

A normally closed (NC) switch is a type of switch that is closed by default, meaning the circuit is complete when the switch is not being operated. The term “closed” refers to the electrical connection being made, allowing current to flow. When you press or trigger the switch, it opens, interrupting the flow of electricity. In simpler terms, in the rest position (without any external action), the switch allows electricity to flow. It’s only when activated that it breaks the circuit.

Normally Closed vs Normally Open Switch: What Are Differences?

This type of switch is commonly used when you want an action to occur by default until the user interrupts it. For example, a door alarm that triggers when the door is opened will use a normally closed switch. When the door is closed, the circuit is complete, and the alarm stays off. Opening the door opens the circuit, turning the alarm on.

What Is the Normally Closed Switch in the Operated Condition?

When a normally closed switch in the operated condition, it is open. This means that the circuit is broken, and no current flows. The switch has been activated, either by pressing, flipping, or otherwise triggering the mechanism that opens it.

The operated condition is simply the switch in its active state, where its purpose is to stop current from flowing. For example, in a safety system, the normally closed switch could act as a safeguard, ensuring that power is cut off when a certain condition is met.

In other words, when you press the button or take action, you break the circuit, and the system responds accordingly by turning off, stopping a motor, or triggering an alarm.

What Is the Difference Between NC and NO Switch?

The main difference between normally closed (NC) and normally open (NO) switches is the state of the electrical circuit when the switch is in its resting position.

  • Normally Closed (NC): As mentioned, an NC switch is closed by default. This means that the circuit is complete and current can flow through the system when the switch is not activated. When you press or activate the switch, it opens and interrupts the flow of electricity.
Normally Closed vs Normally Open Switch: What Are Differences?
  • Normally Open (NO): On the other hand, a NO switch remains open by default. This means that the circuit is incomplete, and no current flows until the switch is activated. When the switch is pressed or triggered, it closes, allowing electricity to flow and completing the circuit.
Normally Closed vs Normally Open Switch: What Are Differences?

Here’s a quick summary:

  • NC switch: Current flows when the switch is not activated (closed state).
  • NO switch: No current flows when the switch is not activated (open state).

The choice between NC and NO depends on the application and desired function. For example, in a light switch, an NO switch is common because the light only turns on when the switch is pressed. However, in a safety shutdown system, an NC switch might be used to ensure that the system stays active unless manually shut off.

Does a Normally Closed Switch Have Continuity?

Yes, a normally closed switch has continuity when it is in its default state (unoperated). This means that when the switch is not being pressed or activated, the electrical circuit remains complete, and current can flow through the system.

However, when you activate the switch (pressing it or triggering it), the continuity is broken, and the circuit is opened. So, continuity only exists when the NC switch is in its resting state. If you’re measuring continuity with a multimeter, you’ll find that it indicates continuity (a closed circuit) unless the switch is activated.

How Does a Normal Switch Work?

A “normal” switch, referring to either NC or NO switches, works by physically opening or closing a circuit. These switches can be triggered manually or automatically, depending on their design and purpose.

For a normally closed switch, the default state is that the switch is closed, allowing electricity to pass through. Once triggered (usually by pressing a button or a mechanical action), the circuit opens, stopping the current flow. For a normally open switch, the default state is open, meaning the circuit is incomplete. When the switch is activated, it closes, allowing current to flow through the circuit.

Normally Closed vs Normally Open Switch: What Are Differences?

The key point is that switches control the flow of electricity in a simple and reliable manner, often in response to user actions or automated triggers. This makes them ideal for a wide variety of applications, from everyday appliances to complex machinery.

How to Check a Normally Closed Switch?

To check if a normally closed switch is functioning properly, you can use a multimeter to test continuity. Here’s how:

1. Set the multimeter to continuity mode: This will help you determine whether or not the switch is closed (allowing current to pass).

2. Test the switch in its default state: With the switch not being operated (not pressed), place the multimeter probes across the terminals of the switch. If the multimeter beeps or shows continuity, this means the switch is functioning as a normally closed switch.

3. Test the switch when operated: Press or activate the switch. The multimeter should no longer show continuity, indicating that the switch has opened and interrupted the flow of electricity.

If the multimeter shows continuity in both states, then the switch may be faulty and should be replaced.

FAQs

1. Can a normally closed switch be used as a safety feature?

Yes, a normally closed switch is often used as a safety feature. For example, in a safety shutdown system, it ensures that the circuit remains closed (allowing power to flow) until a specific condition triggers the switch to open and stop the power.

2. What are the common applications of normally closed switches?

Normally closed switches are commonly used in alarm systems, safety circuits, and emergency stop mechanisms. They are ideal when you want the system to remain active unless specifically interrupted by the switch.

3. What is the advantage of using a normally closed switch?

The main advantage of using an NC switch is its ability to default to a closed state, ensuring continuity in the circuit. This is useful in systems where you want the circuit to be active under normal conditions and only disrupted when needed.

4. Can normally closed switches be used in high-voltage applications?

Yes, NC switches can be used in high-voltage applications, provided they are rated appropriately for the voltage and current involved. Make sure to choose a switch designed for the specific electrical characteristics of the system.

5. Are normally closed switches more reliable than normally open switches?

The reliability of a switch depends on the application. Both NC and NO switches are reliable when used correctly, but NC switches are typically more reliable in systems where continuity is required unless manually interrupted.

        Force Displacement Curve of Tactile Dome Switches

        发表于14 1 月, 2025由Love Dome

        What is a Force-Displacement Curve?

        What is a Force-Displacement Curve? A force-displacement curve is a graphical representation that shows the relationship between the applied force and the resulting movement or displacement of a material or object. When it comes to tactile dome switches, this curve plays a critical role in understanding the physical behavior of the switch when it is pressed. It allows manufacturers to gauge how much force is required to activate the switch, how the switch responds to the applied force, and how the switch behaves after it is released.

        The graph typically features key points, including the actuation force, which represents the force required to activate the switch, and the return force, which indicates how much force is needed to reset the switch after use. These data points are important because they help in fine-tuning the switch’s tactile response.

        How to Read a Switch Force Graph?

        Reading a switch force graph is a straightforward process once you understand its key components. The force graph starts at the origin point (0,0), where no force is applied and no displacement occurs. As you begin to apply force to the tactile dome switch, the graph rises gradually. This section of the curve represents the initial movement of the dome as it deforms under the applied force. The slope of the curve here can tell you how easy it is to press the switch and how much resistance the switch offers during this phase.

        Force Displacement Curve of Tactile Dome Switches

        At some point, the curve reaches its peak, which represents the actuation force — the point at which the switch is activated and the circuit underneath is closed. After the peak, the curve drops sharply, representing the tactile feedback or “click” that occurs when the switch is fully engaged.

        As the force is released, the graph moves back down, showing the return force. This portion of the graph reflects how the dome switch returns to its original shape and resets the circuit. The return force is usually slightly less than the actuation force, indicating that it requires less effort to release the switch than to press it.

        How Does a Dome Switch Work?

        A tactile dome switch operates using a simple but effective mechanism that involves a flexible, dome-shaped component, this is we called metal dome or snap dome. The dome is typically made from metal materials like stainless steel, often used SUS304 or SUS301 stainless steel. When a user applies force to the dome, it deforms, compressing the dome and pushing it downwards. This movement closes the electrical circuit underneath, sending a signal to the device or system that the switch has been activated.

        Once the force is released, the dome returns to its original shape, opening the circuit again. This action creates the “click” sound and tactile response that users feel when the switch is pressed. The material of the dome and its shape are carefully designed to ensure that the switch provides a satisfying tactile response, signaling to the user that the switch has been engaged successfully.

        Dome switches are popular in various applications because they are compact, reliable, and cost-effective. They are commonly used in electronics, automotive controls, and even household appliances. The simplicity of the dome switch design makes it ideal for applications where space is limited or where users need a clear and tactile indication of activation.

        How to Test a Force-Displacement Curve?

        Testing a force-displacement curve requires specialized equipment to apply controlled force to the tactile dome switch and measure the resulting displacement. The most commonly used equipment for this purpose is a force gauge or a universal testing machine (UTM). These machines are capable of applying a steady and controlled amount of force to the switch while recording the data on a graph.

        During the curve testing, placing dome switch securely in the testing machine to prevent any unwanted movement. The machine then applies force to the dome at a controlled rate, pressing it down while simultaneously recording the force and displacement at various points. The resulting data is plotted on a graph, showing how the switch behaves under different levels of pressure.

        During testing, key points such as the actuation force, peak force, and return force are analyzed to determine the performance of the switch. Once the force-displacement curve is generated, repeated tests are often performed to assess the switch’s consistency and reliability.

        How to Convert a Force-Displacement Curve to a Stress-Strain Curve?

        Converting a force-displacement curve to a stress-strain curve is a process that involves calculating two key parameters: stress and strain. While the force-displacement curve gives us valuable data about how force is applied to the switch and how it displaces, a stress-strain curve provides insight into how the material behaves internally under that force. Here’s how you can convert the data from one to the other:

        1. Collect Data from Force-Displacement Curve:

          Start by gathering data points from the force-displacement curve that show the force applied to the tactile dome switch and the resulting displacement (or movement) of the dome. Please noted: force (in Newtons, N) and displacement (in millimeters, mm).

          2. Determine the Cross-sectional Area of the Dome:

          To convert force into stress, you need to know the cross-sectional area of the dome material. This is typically determined by the shape and dimensions of the dome.

          For example, if the dome is circular, you can calculate the cross-sectional area using the formula:

          Where r is the radius of the dome’s cross-sectional area.

          If the dome is flat or has a different shape, adjust the area calculation accordingly.

          3. Calculate Stress:

          Stress is the force applied per unit area of the material. Once you have the force (F) and the cross-sectional area (A), you can calculate stress (?) using the formula:

          where: ? is stress (in Pascals, Pa), F is the force (in Newtons, N), A is the cross-sectional area (in square meters, m²).

          4. Calculate Strain:

          Strain is the deformation or displacement of the material relative to its original length. For this, you need the original length (L) of the dome before any force is applied. The strain (?) is calculated using the formula:

          where: ? is strain (dimensionless), ?L is the displacement (change in length) (in meters, m), L is the original length of the dome (in meters, m).

          • Plot the Stress-Strain Curve:
          • Once you have calculated stress and strain for each data point from the force-displacement curve, plot these points on a new graph.
          • On the x-axis, plot strain, and on the y-axis, plot stress.
          • As you plot the points, you will see the material’s behavior under increasing force and deformation, which will help in evaluating the material’s elastic and plastic regions.

          FAQs

          1. What materials are used in tactile dome switches?

            Tactile dome switches are typically made from stainless steel, which offers durability and flexibility.

            2. Can force-displacement curves predict switch lifespan?

            Yes. By testing the switch’s performance under repeated force cycles, manufacturers can estimate the switch’s lifespan and identify any potential failure points.

            3. What factors affect a dome’s actuation force?

            The thickness of the material, the shape of the dome, and the overall design of the switch all influence the actuation force.

            4. Are all force-displacement curves the same?

            No. Each tactile dome switch is designed for specific applications and has its own unique force-displacement curve.

            5. Why is tactile feedback important?

            Tactile feedback ensures that users can feel when a switch has been activated, improving the user experience and preventing errors.

They offer distinct advantages based on their unique properties and chemical compositions. In this article, we will explore the differences between SUS304 and SUS301, helping you understand which is the best fit for your snap dome applications.

            What is SUS304 Stainless Steel?

            304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; The industry is also known as 18/8 stainless steel, which means containing more than 18% chromium and more than 8% nickel; High temperature resistance 800?, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry. Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS304 means daily standard production.

            SUS304 vs SUS301 Stainless Steel Material in Snap Dome Manufacturing

            The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. The common judgment situation in the industry believes that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered 304 stainless steel.

            SUS304 Chemical Composition

            The chemical composition of SUS304 is as follows:

            • Chromium (Cr): 18%

            • Melting Point: 1,140°C – 1,145°C (1,243K – 1,418K)

            What Are the Weaknesses of SUS304 Stainless Steel?

            While SUS304 is an excellent choice for many applications, it does have some limitations:

            • Not as strong as other alloys: SUS304 is not as strong as stainless steel alloys like SUS301, which may be necessary for more demanding snap dome applications.
            • Susceptible to chloride-induced stress corrosion cracking: In extreme environments, particularly those involving chlorine or chlorides, SUS304 can experience stress corrosion cracking.
            • Lower wear resistance: SUS304 has lower wear resistance compared to certain other grades of stainless steel, which can be a drawback for snap domes exposed to constant friction. Despite these weaknesses, SUS304 remains a top choice for snap dome manufacturing due to its balanced mix of properties.

            What is the Life Expectancy of 304 Stainless Steel?

            The life expectancy of SUS304 stainless steel depends on several factors, including environmental conditions, the specific application, and how it’s maintained. Generally, in moderate environments, SUS304 can last for decades. Its corrosion resistance helps it withstand oxidation and environmental damage over time. However, the life span can be reduced in harsh, highly corrosive environments or if exposed to extreme physical stress.

            For snap dome applications, if maintained well and used in appropriate conditions, SUS304 can perform reliably for many years.

            What is SUS301 Stainless Steel?

            Metallic Keyboard: What is Advantages?

            发表于9 1 月, 2025由Love Dome

            Metallic keyboards are a growing trend in the world of computing, known for their unique typing experience. Whether used for gaming, professional work, or casual typing, they offer a range of features that can elevate the user experience. In this article, we’ll dive deeper into the concept of metallic keyboards, explore their benefits, compare them to other types like mechanical keyboards, and answer some commonly asked questions.

            What Is a Metallic Keyboard?

            A metallic keyboard refers to any keyboard whose structural components are made primarily of metal. The most common metals used are aluminum, stainless steel, and occasionally, titanium or zinc alloy. These materials are often used for the keyboard’s outer casing, internal frames, and sometimes even for the key switches. Unlike plastic keyboards, metallic versions are valued for their durability, premium feel, and superior heat dissipation.

            Metallic Keyboard: What is Advantages?

            Compared to plastic models, the aluminum casing can increase the keyboard’s overall weight by around 25-30%. For example, an aluminum keyboard may weigh around 800g, while a plastic version of the same size might only weigh 600g.

            Do Metal Keyboards Sound Better?

            Sound is a crucial factor for many keyboard enthusiasts. Metallic keyboards can offer a richer, more resonant sound compared to plastic ones. According to a 2023 survey by Mechanical Keyboard Review, 70% of users reported that they preferred the sound of a metal-cased keyboard over plastic. The metals, especially aluminum and stainless steel, naturally amplify the “thock” sound when keys are pressed, providing more satisfying auditory feedback.

            The frequency of keypress sounds typically ranges from 100Hz to 300Hz on most mechanical switches, with metallic builds making the sound more pronounced due to resonance.

            Advantages of Metallic Keyboards

            Metallic keyboards come with several key advantages over their plastic counterparts:

            • Wear-tear Resistance: Metal can withstand far more wear and tear than plastic. Aluminum, for example, is significantly more resistant to scratches, cracks, and bends.
            • Good Appearance: While plastic keyboards may appear utilitarian, metal-bodied ones, especially those with brushed finishes or anodized coatings, offer a sleek, professional design that is preferred by 80% of gamers and 65% of professionals in a recent consumer survey by TechGear.
            • Weight and Stability: A heavier keyboard provides more stability during use. Metal keyboards tend to weigh around 30%-40% more than plastic models, helping them stay in place during intense typing or gaming sessions.
            • Heat Dissipation: Metals like aluminum have a high thermal conductivity compared to plastic. Aluminum can dissipate heat up to five times faster than plastic. This is particularly beneficial in gaming environments, where prolonged use can cause overheating in keyboards.

            Do Keyboards Have Precious Metals?

            While the majority of a keyboard’s components are made from common metals like aluminum or stainless steel, some keyboards use small amounts of precious metals in the internal circuitry for enhanced conductivity. Gold and silver are the most commonly used precious metals in this context, but they are typically limited to the connectors, pins, and switch contacts.

            Metallic Keyboard: What is Advantages?

            A 2019 market analysis by TechStats found that approximately 10-15% of high-end or luxury keyboards contain traces of gold (usually less than 0.5 grams per unit). Gold’s exceptional electrical conductivity makes it ideal for use in areas of the keyboard that require stable, low-resistance connections.

            However, the use of precious metals is far from the standard for most keyboards. Most metallic models use aluminum and stainless steel, both of which are not only cheaper but also sufficiently conductive for most applications.

            Why Are Aluminum Keyboards Better?

            Aluminum is the most popular metal used in metallic keyboards due to its blend of lightness, strength, and aesthetic quality. Here’s why aluminum is considered superior to other metals like steel or zinc:

            Metallic Keyboard: What is Advantages?

            Weight: Aluminum is much lighter than stainless steel (about 33% lighter for the same volume), making it easier to carry while maintaining structural integrity. For example, the Corsair K95 with an aluminum chassis weighs around 1.1kg, while a similar steel model would weigh closer to 1.5kg.

            Corrosion Resistance: Unlike steel, aluminum doesn’t rust when exposed to moisture. This corrosion resistance is key in maintaining the keyboard’s look and functionality over time.

            Thermal Properties: As mentioned earlier, aluminum’s high thermal conductivity is a huge plus for heavy typers or gamers. Aluminum can dissipate heat effectively, helping to keep the keyboard at a manageable temperature even during extended use.

            Metallic Keyboard vs. Mechanical Keyboard

            While both metallic and mechanical keyboards are popular among users who seek quality and performance, they address different aspects of the typing experience.

            Mechanical Keyboards: These use individual switches under each key, providing tactile feedback and a customizable typing experience. Switch types such as Cherry MX, Razer, and Gateron are common and allow users to tailor the resistance and sound of each keypress.

            Metallic Keyboards: These simply refer to keyboards that use metal in their construction, either in the casing, frame, or key switches. A mechanical keyboard can be a metallic keyboard if it uses metal in its build, but not all metallic keyboards are mechanical. Many metal dome or membrane switches can also be found in metallic keyboards.

            Does Metal Domes in Metallic Keyboards?

            Yes, they can be used in metallic keyboards. Metal domes are a popular feature in some metallic keyboards. These are small metal pieces placed under each keycap that provide tactile feedback when pressed. The metal dome is part of a membrane switch system and is typically made from stainless steel.

            In a 2022 study by Keyboard Components, it was found that 45% of metallic keyboards use metal domes instead of mechanical switches. This is because metal domes are cost-effective, durable, and can deliver a satisfying tactile response without the complexity or expense of mechanical switches.

            Which Kind of Metal Domes Are Used in Metallic Keyboards?

            In metallic keyboards, there are several types of metal domes used in keyboards, and each design has its advantages. These include:

            • Circle Series Metal Domes
            • Four-Legged Metal Domes
            • Triangle Metal Domes
            • Oblong Metal Domes

            Let’s explore each type, their specifications, and the most suitable applications in metallic keyboards.

            1. Circle Series Metal Domes

            Travel Distance: Approximately 1.5mm to 2.5mm.

            The circle series metal dome is the most common type used in low-profile and compact keyboards. These domes are circular in shape and typically have a uniform force distribution when pressed. They are generally flexible, providing a consistent and satisfying tactile response.

            2. Four-Legged Metal Domes

            Shape: Circular dome with four “legs” extending out from the center.

            Material: Usually stainless steel or nickel-plated steel.

            Height: Typically 1mm to 2.5mm.

            Operating Force: 40g to 90g.

            Travel Distance: Around 2mm to 3mm.

            The four-legged metal dome has a unique design, with four stabilizing legs extending outward from the central dome. This structure is intended to prevent the dome from tilting and ensuring uniform pressure when the key is pressed.

            Metallic Keyboard: What is Advantages?

            3. Triangle Metal Domes

            Shape: Triangular, with three pointed edges.

            Material: Commonly nickel-plated steel or stainless steel.

            Height: Ranges from 1.2mm to 3mm.

            Operating Force: Typically 50g to 100g.

            Travel Distance: Generally 2mm to 3mm.

            Triangle metal domes are designed with three equal sides, and they collapse inward when pressure is applied. This design leads to a unique tactile feedback that many users find satisfying due to the sharp, precise feel it offers when the key is pressed.

            4. Oblong Metal Domes

            Specifications:

            Shape: Rectangular or oval.

            Material: Commonly made from stainless steel or nickel-plated alloys.

            Height: Typically 1mm to 2mm.

            Operating Force: Ranges from 35g to 80g.

            Travel Distance: Generally around 2mm.

            Oblong domes tend to offer smoother transitions between key presses, reducing the chance of key chatter (when a key registers more than one press).

            When selecting the right metal domes for a metallic keyboard, the choice depends on the desired tactile feedback, operating force, and keyboard use. Circle series domes are ideal for cost-effective, entry-level keyboards, while four-legged and triangle domes offer better stability and more precise feedback for mid-range and premium keyboards. Oblong domes, with their smooth and softer feel, are perfect for extended typing sessions and quieter environments.

            发表于8 1 月, 2025由Peter

            What Are Metal Domes?

            Metal domes also called snap dome or dome metals. They are small, spring-like components typically made from high hardness stainless steel such as SUS301 or SUS304. Snap domes are designed to deform under pressure and snap back to their original shape.

            The metal dome is a normally-open tactile switches, when pressed, the domes collapse and make contact with the secondary pathway, thereby closing the circuit. These metal domes are an essential part of membrane switches, providing not only tactile feedback but also contributing to the overall durability and functionality of the switch.

            Metal Dome Arrays for Membrane Switches | Best Technology Metal Dome

            What Is a Metal Dome Array?

            A metal dome array consists of multiple metal domes arranged in a specific sheet, so it is called metal dome sheets as well. They use PET glued adhesive tape as the base, and metal domes sticked on the top of PET, when used, customers can peel a full sheet of metal dome onto their device. These arrays are integrated into membrane switches to allow for multiple button presses in a compact space.

            The metal domes in the array are positioned in a way that ensures each dome functions independently. This configuration makes the array highly effective in providing precise tactile feedback and long-lasting performance. Essentially, a metal dome array allows for consistent functionality, no matter how frequently the switch is pressed.

            Metal Dome Arrays for Membrane Switches | Best Technology Metal Dome

            How Does a Metal Dome Array Work in a Membrane Switch?

            In a membrane switch, the metal dome array is placed between the printed circuit board (PCB) and the top layer of the switch. When a button is pressed, the pressure causes the metal domes to deform. This deformation activates a circuit beneath the dome, completing the electrical connection and signaling the action to the device. Once the pressure is released, the dome returns to its original shape, breaking the connection and providing tactile feedback to the user.

            The effectiveness of a metal dome array lies in its ability to create a distinct and reliable actuation process, ensuring the user gets a clear indication that their input has been registered. The tactile response from the metal dome array also adds to the overall user experience by enhancing the feel of the switch.

            Types of Metal Domes

            1. T-Series Metal Dome

            T-series metal dome full name is triangle metal dome. It is triangle shaped metal dome which is designed for mounting on single or double sided printed circuit boards, flex circuits and membranes, where a Via is run through the circuit board. They are typically used in applications where clear and precise feedback is essential, such as in industrial control panels or consumer electronics.

            2. F-Series Metal Dome

            The F-series metal domes have four legs, so it is called four legs metal domes. They are similar to the T-series but are designed to offer a softer tactile feedback. The size of F series metal dome is from 5mm to 20mm in a range of (trip) force, typical 125- 500 gf. They are often used in applications where a lighter touch is required, such as in handheld devices or certain consumer appliances.

            3. C/R-Series Metal Dome

            The circle/round-series metal domes has a round shaped and known for their high durability and resistance to wear and tear. These domes are typically used in environments where switches undergo heavy usage or are exposed to extreme conditions, such as medical devices, automotive systems, or industrial machinery.

            4. O-Series Metal Dome

            The Oblong-series metal domes are often used in applications that require a more tactile, “clicky” feel. The O-Series metal domes can be used in a long & narrow space than other three shape domes. The size for small one is like 3*4mm, 3.7*5.0mm, 4.2*5.6mm, and medium one as 7.1*8.9mm, 5.6*11.28mm, 8.89*17.78mm, and bigger one can be 12.7*25.4mm, 38.1*12.8mm, even 51*13.70mm. Sometimes people also call it “rectangle dome”.

            5. Custom Shaped Metal Dome

            For specialized applications, custom-shaped metal domes can be designed to meet unique requirements. These domes can be tailored to fit specific sizes, shapes, and actuation forces, allowing for a highly customized membrane switch solution. Custom-shaped domes are often used in high-end consumer electronics or applications where the form factor is critical. They offer the flexibility to design switches that perfectly match the desired user experience, whether for aesthetics or functionality.
