ABSTRACT:
An electronic switching circuit is provided for controlling transfer of electrical power from an alternating polarity electrical power supply to a load means through use of a field-effect transistor device as a primary power controlling element. The circuit also is arranged such that the alternating polarity electrical power supply provides power for operating further circuit components used to direct operation of the primary power controlling element. Certain of these further circuit elements can be prevented from drawing electrical power in certain situations.
