ABSTRACT:
A push-button switch in which a resilient conductive elastomer bridging contact member is compressed directly against two or more printed conductors between which it is desired to selectively make and break electrical continuity. The conductive elastomer member is used as a beam having a central portion in contact with the printed circuit board for mechanical support. The member is formed so that it diverges from the plane of the conductors on the circuit board outwardly from the central mechanical support portion, mechanical compression as by a push-button arrangement elastically deforming the member into contact with the printed circuit conductors. Release of this compressive force permits the member to resume its initial shape correspondingly breaking the electrical continuity.
