ABSTRACT:
An improved low cost electrical switch has a two-piece housing comprising a base and an escutcheon. The escutcheon includes a frame and a face plate which is flexible, resilient and insulative. Application of downward finger pressure on the face plate causes the face plate to deform, thereby urging a snap action dome into a shorting position across a pair of electrical contacts.
