Switch assembly incorporating contact wedge
First Claim
1. A switch assembly comprising:
- a housing;
first and second electrical contacts extending within said housing and including first and second contact zones respectively; and
a push button including a wedge member and at least one camming surface, said push button being shiftable between a first position, wherein the wedge member projects between the first and second contacts to maintain a space between the first and second contact zones, and a second position, wherein the first and second contacts are forced into engagement at the first and second contact zones by the at least one camming surface abutting each of the first and second contacts.

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.
