ABSTRACT:
An electrical switch includes a casing, an actuator, and a switch mechanism. The switch mechanism includes a contact bridging member movable between a plurality of spaced electrical contacts. The contacts act as fulcrums on the contact bridging member during its movement to assist in making and breaking the electrical connections. A conductor connects the contact bridging member to one of the contacts or to a second switching mechanism mounted in a common housing.
