Electrical switch
First Claim
Patent Images
1. A electrical switch comprising;
- an electric insulator formed as a continuous sheet and adapted to be penetrated by a manually held probe,a first electrical conductor mounted on one side of said electric insulator, anda second electrical conductor similar to said first electrical conductor mounted on the opposite side of said electric insulator for causing contact between said first electrical conductor and said second electrical conductor, upon rupture of said insulator, to close said switch, said first and second electrical conductors comprising soft, flexible, metal foil adapted to be penetrated by a manually held probe.

Abstract
A normally open laminated electrical switch comprises a sandwich of two electrically conductive sheets on opposite sides of, and separated by, a thin layer of insulation. Upon rupture or discontinuity of the thin insulative layer, the electrically conductive sheets are adapted to contact each other and to close the switch.
