Abstract:
1. An electrical load control circuit using low voltage for remotely selectively energizing or de-energizing an electrical load comprising: a series of several inputs suitable for low current connections to remote switches; a conceptual exclusive OR circuit for producing a first DC control signal in said conceptual exclusive OR circuit one output state and a second DC control signal in said conceptual exclusive OR circuit second output state in response to the states of the several inputs, such that the change in stage of any one of said series of inputs will change the state of said conceptual exclusive OR circuit output; a latching relay adapted for switching AC power applied to an electrical load from an AC supply source controlled by the output of said conceptual exclusive OR circuit which relay is energized to change states but is otherwise not generally energized to maintain a given state; and an output controlled by said relay for connection to a lead to an electrical load and a lead to an AC supply.
