Abstract

A pressure activated switching device includes an electrically insulative standoff positioned between two conductive layers. The standoff is preferably a polymeric or rubber foam configured in the form of contoured shapes having interdigitated lateral projections. Optionally, the switching device can include a piezoresistive material positioned between a conductive layer and the standoff. The pressure activated switching device can be used, for example, in a safety sensing edge system for a movable door.
