Components of a Membrane Switch


Graphic Overlay

Graphic overlays are a thin film with a printed layer that acts as the product’s top surface. They can be decorative or simple in design. You can emboss graphic overlays, or the graphic can help indicate switch locations.



Keypads are a set of buttons arranged in a block that become the interface of products. Keypads offer a wide variety of options to achieve the desired user experience. Common keypad materials are:

Compression-molded elastomer materials
Hard keys mounted in a bezel
A combination of hard key and elastomers



Pressure-sensitive adhesives are thin layers of tape that adhere domes to the circuit. Adhesives can help protect the switch from debris, provide a moisture barrier, or other environmental factors.


Metal Domes

Metal domes are normally-open contacts that, when pressed, complete the circuit. Metal domes, also known as tactile domes, create tactile feedback for the user and come in a wide variety of sizes, styles, and forces. Domes have life ratings of up to 10 million presses. Snaptron can produce custom domes with minimal lead times.
