Application of metal dome in keyboard

Metal domes can be used in all types of environments and these keyboards can also be customized according to the needs of the user. Metal domes, usually made of stainless steel, are momentary switch contacts that provide a tactile feel or “snap” when pressed. Connect the two circuit board traces together under the metal dome keyboard. The metal dome also exhibits excellent tactile feedback in membrane switches, while also backlighting the metal keypad.

How Membrane Switches Work

Here’s how the metal dome works in a membrane switch: The metal dome switch is a formed stainless steel piece that provides positive tactile feedback to the user when compressed. When the key is not pressed, the membrane switch is in the normally open state, its upper and lower contacts are disconnected, and the isolation layer isolates the upper and lower lines; when the key is pressed, the upper contact point of the circuit deforms downward and merges with the lower circuit, so that The circuit is turned on. When the key is pressed, it folds the dome, connecting the two circuit traces and completing the connection to enter characters.

Advantages of metal domes

Metal domes are preferred for electronic keyboards because of their resilience and excellent tactile feedback in applications that respond quickly. The application of the metal dome in the keyboard allows the user to immediately know that the keyboard is receiving their actions because they can feel the response of the metal dome switch. Metal domes also have a longer lifespan specification in electronic keyboards, not least because of their reliability of over 5 million cycles. Metal dome switches can be plated with nickel, silver or gold. The automotive industry has particularly chosen to use metal dome keyboards because the integrated metal dome ensures a long lifespan and excellent tactile feel.

Design features of metal domes

The design and production process of the metal dome switch in the keyboard, you can customize the size, shape, tripping force, rebound force or travel, with legs or with holes, we will all according to your design, drawings, samples for your application Provides accurate metal domes. Gives you the tactile feedback you need. As electronics get smaller, metal domes must be manufactured in sizes as small as 3 millimeters in diameter. These smaller tactile domes present manufacturing challenges for production designers. Therefore, we constantly confirm with customers in production to solve some potential problems.

Metal domes are used in electronic keyboards, and there is also a problem with the alignment of the dome switches. I wrote about how to install a metal dome before. Metal domes offer numerous advantages in terms of durability and robustness in electronic keypad applications. The metal dome is used as the switch of electronic equipment in the membrane switch, you can place the metal dome in each display according to the design purpose, we can produce according to your drawing and ensure the quality of the product.
