ABSTRACT:
An electrical switch assembly having a first switch contact member behind a housing panel which has an opening through which the shank of a bolt extends. The bolt shank carries a second switch contact member for engagement with the first switch contact member. An enlarged head on the bolt has a flat rear face for engaging the front of the housing panel around the opening. A rigid washer on the bolt shank is spaced slightly farther from the rear face of the bolt head than the thickness of the panel at the opening, so that normally the shank of the bolt tilts downward inside the housing. This establishes a first position of the second switch contact member, which is on the bolt shank, with respect to the first switch contact member. A person's finger pressing on the bolt head can raise the bolt shank to establish a second position of the second switch contact member.
