ABSTRACT:
A system of controlling the operation of an AC load with a switch placed in series with the load, which switch is itself operated by dc control logic powered by power loss experienced by the switch which the logic controls. Numerous elements in the control system perform multiple functions allowing the control logic to remain alive during both the on and off mode of the switch without power being provided to the logic by separate conductors to the AC power source, such that the control system is completely self powered and self regulated by simply placing the system, with two wires, into a series loop with the AC power source and the load.
