A membrane switch is a momentary switching device that is
manufactured by using a series of flexible layers of polymer
films and adhensives. The upper-most layer, called a graphic
overlay, is manufactured by printing on the second surface of
clear polyester or polycarbonate film. Membrane switches can be
constructed with multiple circuit layers, and more elaborate
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 capablities to create the ideal custom user
interface for their products.
