Capacitive switching assembly

A capacitance change switch with a resiliently deformable conductive pad compressible against a dielectric coating on the surface of a pair of spaced coplanar thin foil plates formed on a refractory substrate. The pad forms with the plates a pair of capacitors electrically in series. User movement o...

Summary:A capacitance change switch with a resiliently deformable conductive pad compressible against a dielectric coating on the surface of a pair of spaced coplanar thin foil plates formed on a refractory substrate. The pad forms with the plates a pair of capacitors electrically in series. User movement of an actuator causes pad compression and a significant electrically detectible change in capacitance for effecting a switching function. In one embodiment the pad is formed of conductive elastomer and in another embodiment the pad is formed of non-conductive elastomer with a conductive foil covering.
