What is Membrane Switch?

The membrane switch is a momentary switching device that is manufactured by using a

series of flexible layers of polymer films and adhesives. The top layer, called a graphic

overlay, is manufactured by printing on the down surface of transparent polyester or

polycarbonate film. Membrane switches can be constructed of multiple circuit layers, and

more optimized graphic design features, such as domed key embossing. Designs that are

more complex require more material layers for proper construction and reliable operation.

Membrane switches, when combined with components such as a tactile dome, graphic

overlay, or integrated LEDs or resistors can provide the designer with virtually limitless

capabilities to create the ideal custom user interface for their products.
