ABSTRACT:
A momentary contact rocker switch utilizes a pair of torsion springs as movable switch contacts, with fixed terminal posts being used as fixed contacts. The terminal posts are grooved in the region of contact with the torsion spring to provide a wiping action. This wiping action, along with the high electrical contact forces provided by the torsion spring, eliminates the need for silver contacts.
