Control for remote control wiring system

Abstract

A remote control wiring system is provided which includes a transformer for providing power to a low voltage subsystem which, through relays, controls the opening and closing of higher voltage load circuits of the remote control wiring system. A plurality of relays are provided, one for controlling each of the load circuits. A first circuit includes in series a first solid state switching device, such as a suitable transistor, SCR or triac, and a relay, or a plurality of relays connected in parallel. Similarly, a second circuit includes in series a second solid state switching device, such as a suitable transistor, SCR or triac, and the relay, or the plurality of relays connected in parallel. A two-position switch is incorporated in the low voltage subsystem in association with the first and second circuits. In one position of the switch the first circuit is closed through the first solid state switching device to energize the aforementioned relay or relays for closing the load circuit or circuits associated therewith. In a second position of the switch the second circuit is closed through the second solid state switching device to energize the relay or relays for opening the load circuit or circuits.
