Abstract

An elastomeric membrane switch having an elastomeric connector comprising a plurality of alternating vertically disposed conductive layers and non-conductive layers extending between upper and lower contact surfaces. The lower surface of the elastomeric connector is disposed over a substrate having electrically isolated, first and second contact pads of an electrical switch circuit. Each of the first and second contact pads is in electrical contact with different ones of the exposed ends of conductive layers of the lower contact surface. A resilient membrane having an electrically conductive interior surface is spaced a distance above the upper contact surface, whereby upon applying a downward force to the resilient member, the otherwise electrically isolated contact pads are electrically connected through the electrically conductive layers of the elastomeric connector and the electrically conductive interior surface of the resilient member.
