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.
