Abstract
An electrical switch assembly includes a first contact supported for movement into and out of electrical connection with a second contact. A cam assembly is configured to deflect a spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition. A motor has an output member. A linkage interconnects the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member.
