Custom waterproof metal dome membrane photoelectric switches for
Medical appliances / ZS-87 / Flat and tactile overlay
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.
