ABSTRACT:
Disclosed is a switch for selectively connecting an electrical system to a source of electrical power, such as a battery. At least two electrically conductive bodies are mounted within a switch housing in spaced relation to each other and in communication with a housing chamber. Fastening means are provided for connecting each conductive body to an electrical cable. An electrically conductive contactor carried within the chamber is movable between a closed position in contact with each conductive body and an open position out of contact with each conductive body. A first biasing means presses the contactor into engagement with the conductive bodies in response to movement of an actuator means toward a first position and a second biasing means snaps the contactor out of contact with the conductive bodies in response to movement of the actuator means toward a second position, actuator movement being responsive to a mechanical or electrical signal produced remotely from the switch housing. The first and second biasing means may comprise first and second spring members, respectively, with the spring constant of the first member being substantially greater than the spring constant of the second member and the effective length of the first member being substantially less than the effective length of the second member.
