At Best Technology, we don’t just offer dome arrays—we craft them to meet your specific needs. Whether you’re designing a rugged medical device or a sleek consumer electronic product, our dome array design is available and fully customizable.
What is a dome array?
Dome array is a sheet-like structure that holds multiple metal domes, typically adhered to an adhesive or PET sheet. These metal domes act as tactile switches. When pressed, they snap and create a short circuit, sending a signal to the device.
It’s more than just a switch—it’s the heart of tactile feedback. Each dome’s shape, size, and material affects how it feels, how long it lasts, and how it performs.
You’ll find dome arrays in medical equipment, smart appliances, industrial control panels, and more. Anywhere that needs a reliable and responsive button, a dome array is likely in use.
What is custom dome array design?
Custom dome array design is the process of creating a unique array tailored to your exact requirements. It involves choosing:
- The right metal dome size
- The perfect layout to fit your panel
- The correct actuation force (how hard you press)
- The right shape for the tactile feel
- Ideal spacing between domes
- PET sheet thickness and adhesive strength
Dome array that fits perfectly into your product, functions flawlessly, and enhances user experience. Dome array design available means you don’t have to settle for a “one-size-fits-all” solution. You get one that fits only you.
Why choose a custom dome layout?
When you’re designing high-end electronics or mission-critical equipment, every detail matters. You decide where each dome sits, how many you need, and how they align with your circuit board or overlay.
With a standard dome sheet, you may face problems like:
- Misalignment with key graphics
- Unresponsive keys
- Uneven tactile feel
- Reduced product lifespan
Custom dome layout eliminates those risks. You get consistent, responsive performance across every key. It also improves reliability, boosts durability, and delivers that satisfying tactile response users love.
How to customize dome array?
At Best Technology, customizing your dome array is simple and efficient. Here’s how the process works:
Step 1: Share Your Requirements
Tell us what you need. Whether it’s a drawing, a prototype, or just a concept, we’re here to help you build it. Let us know:
- Key locations
- Required dome sizes and shapes
- Desired actuation force
- PET/adhesive preferences
- Circuit interface (if needed)
Step 2: We Provide a Design
Our engineers create a dome array layout that matches your application. Every dome is carefully positioned, and the sheet is designed to match your housing or PCB.
Step 3: Sample for Testing
We send you a sample for real-world testing. You’ll feel the snap, test the alignment, and verify the performance before mass production.
Step 4: Full Production
Once you approve, we move fast. Our factories in China and Vietnam are equipped for rapid, high-precision manufacturing. From low to high volume, we deliver fast.
How does a dome array work?
Each metal dome in the array rests over a pair of conductive pads on your PCB or FPC. When you press the dome, it flexes and touches both pads, closing the circuit. As soon as pressure is released, the dome snaps back to its original shape.
This “snap” gives you tactile feedback. You feel the press, and the device knows the command.
Well-designed dome arrays are fast, reliable, and incredibly precise. They respond to every press without delay. That’s why they’re trusted in life-critical devices like hospital monitors and emergency control panels.
What dome sizes and shapes are available?
Different applications call for different sizes and shapes. Here’s a quick guide:
- Round domes (standard): Common in most consumer products. Smooth snap feel.
- Four-leg domes: Great for large keypads. High stability and tactile clarity.
- Triangle domes: Sharp tactile response. Used in compact spaces.
- Oblong domes: Ideal for long or custom-shaped buttons.
Sizes usually range from 4mm to 20mm, depending on your layout. The actuation force can be tailored too—light touch or firm press. Want to add embossing or LED light guides? We can design around those too.
How to select the right metal dome?
Choosing the right dome isn’t just about size. It’s about feel, function, and longevity.
- Click feel: Light, medium, or strong snap? We offer options from 100g to 500g force.
- Durability: Need millions of presses? We offer domes with over 1 million lifecycle.
- Environment: Humid or dusty settings? Ask for sealed or waterproof layers.
- Speed: Want instant actuation? Choose domes with low resistance and faster response time.
Every project is different. You tell us your goals, and we’ll match the dome to your exact needs.
