Switch assembly incorporating contact wedge

Abstract

A switch assembly includes both a separating wedge member, which functions to maintain two electrical contacts out of electrical communication, and a second, camming element, which can be used to squeeze the contacts together when the switch assembly is actuated. In a first embodiment, the second element is of a generally conical shape. In a second embodiment, the second element is actually constituted by two side members having ramped surfaces. The interaction of the specially shaped contacts and camming element ensures proper mating of the contact members when the switch is actuated. In one preferred form of the invention, an undulating channel is formed in a housing of the switch to pinch connecting wires and assure a positive, reliable connection with the contacts.
