Abstract
A plunger which opens and closes a switch is actuated by a hollow switch button which is trapped between a switch housing and a post which carries the plunger. An edge of the post bearing against the inside corner of the hollow button and the chamfered ends of the button flanges bearing against the intersection of the open end housing walls and a rim extending from the walls provide the button pivot axis to actuate the plunger. The switch includes two resilient blades one of which is longer than the other. One end of each blade is fixed with their distal ends pointed toward and overlapping each other.
