Abstract

A pressure actuated switching apparatus includes first and second conductive layers and a plurality of discrete spaced apart dots between the first and second conductive layers. The dots serve as a standoff for separating the conductive layers and are fabricated from an insulative, elastomeric polymer foam which can collapse under the application of compressive force applied to the apparatus to allow contact between the conductive layers with minimized dead space. Alternatively, the standoff can include strips of electrically insulative elastomeric polymer foam.
