ABSTRACT:
An electric switch is either automatically actuated by a motor driven timer or manually actuated, as determined by turning a three-position selector. The timed switch may be used with a conventional motor-driven clock and uses a commercially available microswitch which can provide either timed-"ON" or timed-"OFF" operation. Rotation of the selector in either direction causes longitudinal displacement of a spring-loaded actuator, which operates the switch. The selector has latching arms which are latched either in a manual position or in the automatic timed position.
