Abstract

A multi-function touch switch apparatus has a first semiconductor composition layer disposed on top of a first conductor layer which is affixed to a first base member. A second semiconductor composition layer opposing the first semiconductor in spaced relationship thereto is disposed on a second conductor layer which is itself disposed on the bottom surface of a second support member. A third conductor layer is also disposed on the top surface of the second support member in opposing spaced-apart relationship to a fourth conductor layer disposed on the bottom surface of a third support member. The second and third support members and the affixed conductor layers and semiconductor layers are resiliently deformable in a transverse axis in response to a transverse touch force to thereby cause electrical contact between the second and third conductor layers to provide a closed switch and the first and second semiconductor layers to provide a closed switch in series with a pressure sensitive resistance.
