Abstract
A pushbutton switch comprising a housing within which a pushbutton can move ith respect to a housing socket is described. Within the housing is placed a switch plunger which moves longitudinally and can also pivot through a small angle. A contact bridge, which can be pivoted in an oversprung fashion between two fixed contacts, is disposed in the housing. The placement of the contact bridge is governed by a switch rocker, which is arranged in a hinged fashion in the housing. This allows the switch plunger and switch rocker to engage. The counterbearing for the contact bridge consists of a knife-edge bearing in the switch rocker. Between the switch plunger and the switch rocker is a return spring, arranged so that in the rest position of the pushbutton, the switch plunger occupies a pivoted position remote from the middle position. The cross motion of the switch plunger is halted, depending on the direction of motion of the pushbutton, by a constraining guide on each side.
