ABSTRACT:
A timed actuator moves the switch mechanism of a conventional wall switch. The actuator is detachably secured to the wall switch in abutting relation thereto. The actuator includes a small electric motor, a programmable timer, and several relays. Linkage, driven by the motor, engages the switch mechanism. The programmable timer drives the relays and the latter controls application of current to the motor. At preset times, current is applied to the motor causing the linkage to move the switch mechanism from one extreme of its travel to the other.
