Abstract: The invention provides a novel electroconductive rubbery member which is a shaped body of a conductive rubbery elastomer impregnated with a powdery conductive particulate material such as carbon black or a metal powder dispersed in an insulating rubber, in which a multiplicity of conductive fibrous bodies such as carbon fibers or very thin metal wires are embedded in such oriented dispersion that each of the fibrous bodies lies along a line which intersects the surface of the shaped body and at least a part of the fibrous bodies are protruded out of the surface of the shaped body. By virtue of the protruded fibrous bodies, very reliable electric conduction is obtained between the conductive rubbery member and the metal electrode in contact therewith. Further advantages are obtained by providing an insulating coating film of, preferably, an adhesive on the contacting surface of the conductive rubbery member penetrated by the protruded conductive fibrous bodies. The inventive conductive rubbery members are also useful as the conductive parts of an elastic connector having an alternately stratified structure of conductive rubbery strata and insulating rubbery strata.

Abstract: A dual switch apparatus has two switches simultaneously actuated in response to a single touch force where at least one of the switches has a pressure responsive variable contact resistance. A first support member has a first and a second conductor disposed thereon and a second support member has a third and a fourth conductor disposed thereon so that the first and third conductors and the second and fourth conductors have mirror image conductor patterns. A semiconducting composition layer is disposed to cover at least one of the four conductors. The first and second support members are positioned facing one another with the first and third conductors and the second and fourth conductors transversely aligned so that a transverse force causes the first and third conductors and the second and fourth conductors to move into electrically conducting relationship. A spacer maintains the first and second support members in normally spaced relationship. A utilization circuit may be coupled across each of the first and third and second and fourth conductors. In one embodiment, the first conductor has two electrically isolated contact members with interdigiting fingers with the third conductor acting as a shunt.

Abstract: A multiple touch switch apparatus has at least one multiple segment conductor ply on the top surface of a support ply. The segments are electrically insulated from each other by their lateral displacement but are immediately adjacent so that a selected one or more of the segments can be contacted in response to a single transverse touch force. A second support ply has a unitary conduction ply on its bottom surface spaced apart from, but facing, the multiple segment conductor ply. At least the second support ply and the unitary conduction ply are resilient deformable into contact with one or more segments of the multiple segment conductor ply. Each of the multiple segment conductors or the unitary conduction ply or both may incorporate a conductor layer and a pressure sensitive semiconductor composition layer disposed thereon. The semiconductor layer provides a pressure sensitive variable contact resistance in series with the switch. In another embodiment, each multiple segment conductor ply may be replaced by a single segment conductor.
