ABSTRACT:
A switch for selectively interconnecting wires of electric cable provides an enclosure having an input port and an output port and a toggle switch. A cam having cam arms is movable between a first position where the arms electrically connect and close contact points of return bus segments and a second position where the arms electrically connect and close contact points of a power bus segment and a return bus segment. A power bus extends in segments between the input port and the output port and has a main contact point selectively opened and closed by the toggle switch. The power bus has a power bus cam contact point selectively opened and closed by the cam. A return bus extends in segments between the input port and the output port and has return bus cam contact points selectively opened and closed by the cam. A ground bus extends between the input port and the output port. A second power bus and an auxiliary cam can be added for various three way switch wiring configurations.
