ABSTRACT:
Membrane switch comprises a substrate having first, second, and third switch contacts thereon. A flexible insulating film extends parallel to the substrate and has a commoning conductor on its underside. The flexible film has first and second contact projections extending towards the substrate, the first contact projection being against the first switch contact and the second contact projection being spaced from the second switch contact. A pair of supporting projections extend from the film and bear against the surface of the substrate at locations adjacent to the switch contacts. The film is supported by the first contact projection and the air of supporting projections. When the film is pressed towards the substrate, the second contact projection sequentially moves against the second switch contact and thereafter the commoning conductor is moved against the third switch contact.
