Abstract
A snap acting electrical switch in which a frame carries first, second and third wireform contacts and a plunger movable along a first axis. The first and second wireform contacts are biased together along a second axis transverse to the first axis, and are also biased against an end of the plunger. The first and second wireform contacts together are adapted to be deflected along the second axis by a cam surface on the housing as the plunger is depressed. As the second contact is caused to slide off the end of the plunger, it snaps against the third wireform contact which is in a fixed position along side the plunger.
