Claim 10

An electronic switching circuit as set forth in claim 7 wherein the manually operable resetting means and said means for deenergizing the power control switching circuit are comprised by a single pole, double throw switch having a first position for manually effecting energization of said portion of the utilization equipment and having a second position for manually effecting deenergization of said portion of the utilization equipment in the absence of a temporary power interruption.

Claim 11

An energy conservation method comprising: automatically and temporarily interrupting at predetermined times the supplying of power from a power source to at least a portion of utilization equipment such as lighting equipment and the like; automatically opening the circuit between the power source and said portion of the utilization equipment in response to the temporary interruption of power by turning off a semiconducting device; and maintaining the circuit between the power source and said portion of the utilization equipment open and the semiconducting device off after the temporary interruption of power ceases until said semiconducting device is manually caused to be turned on, whereby said portion of the utilization equipment is automatically deenergized upon interruption of the power thereto and remains deenergized until the circuit is manually caused to be closed.

Claim 12

An energy conservation method comprising: automatically and temporarily interrupting at predetermined times the supplying of power from a power source to at least a portion of utilization equipment such as lighting equipment and the like; automatically opening the circuit between the power source and said portion of the utilization equipment in response to the temporary interruption of power by turning off a semiconducting device; and maintaining the circuit between the power source and said portion of the utilization equipment open and the semiconducting device off after the temporary interruption of power ceases until said semiconducting device is manually caused to be turned on, whereby said portion of the utilization equipment is automatically deenergized upon interruption of the power thereto and remains deenergized until the circuit is manually caused to be closed.
