ABSTRACT:
A manually operated electrical switch includes a first conductor and a second conductor. The second conductor is telescopically coupled to an electrical contact arranged to be spring biased against an opposing surface. The second conductor is attached to an electrical insulator and assembled in a housing so as to be pivotally movable over an arcuate path between a first position in which the first conductor is in electrical contact with the second conductor and a second position in which the first conductor is electrically insulated from the second conductor.
