Title: Arch shaped snap-type switch contact

Abstract: A switching plate having a plurality of arch-shaped snap-type switching members formed in a continuous metallic sheet or from sections of a metallic sheet bonded to an insulating substrate. Adjacent of the switching members extend in transverse directions. The switching members will snap downward when forced sufficiently downward thereby achieving contact or capacitive switching. The switching members are formed in a metallic sheet by providing a first plurality of groups of parallel slots in one direction and a second plurality of groups of parallel slots in a transverse direction, one of the slots of the first group being longer than the other slots. The sheet is placed in a die having members conforming in shape to the desired arches, wherein the sheet is deformed elastically at desired locations to provide the arch-shaped snap-type switching members.
