When a press force is applied to the movable contact portion (4), the movable contact portion is elastically deformed against resilience thereof toward the contact edge (30) to come into contact with the edge or an area adjacent thereto. When the press force is released, the movable contact portion (4) is elastically restored to move its projection (6) away from the contact edge (30) or the adjacent area. | ||||||

| 14 | Dual lateral switch device | US135386 | 1980-03-31 | US4301337A | 1981-11-17 | Franklin N. Eventoff |
| 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. | ||||||

| 19 | Electronic pressure sensitive force transducer | US492536 | 1983-06-13 | US4489302A | 1984-12-18 | Franklin N. Eventoff |
| A bounceless switch apparatus having a junction resistance which varies inversely with the pressure applied normally thereto which includes a first conductor member, a pressure-sensitive layer including a semiconducting material covering the first conductor member in intimate electrically conducting contact therewith and a second conductor member positioned in nonelectrically conducting relationship to the pressure-sensitive layer. The pressure-sensitive layer has a first surface with a multiplicity of microprotrusions of the semiconducting material which provide a multiplicity of surface contact locations. As the normally open switch is closed in response to a pressing force applied to urge the second conductor member and the first surface together, the physical contact between the microprotrusions and the second conductor increases thereby variably increasing conduction between the first conductor member and the second conductor member. | ||||||

| 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. | ||||||
