What is Membrane Switch ?
A membrane Switch is a momentary switching device that is manufactured by using a series
of flexible layers of polyester films and adhesives. 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.
All products are 100% quality tested and monitored carefully prior to
shipment.
State-of-the-art testing equipment.
Efficient assembly and packing lines
All products compliant with RoHS and other regulations
Strict assembly, reliability and functional tests to ensure the
