What is Membrane Switch
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 complicated 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.
