ABSTRACT:
A high sensitivity door edge switch including an openwork or perforate spacer for extension along a door edge, flexible conductors on opposite sides of the spacer in spaced apart confronting relation through the spacer perforations, and a resiliently compressible deflection element in facing relation with the spacer, the deflection element being elastically deformable into the spacer perforations to flex the conductive elements into engagement with each other upon low unit pressure applied to the deflection element, even over a large extent.
