Abstract
A compact electronic assembly operable to control the energization of an electrical appliance is adapted for convenient mounting in an existing, standard electrical wall-switch box. A disconnectable electronic control means is mounted on the outside of the switch face plate and communicates with circuitry inside the wall-switch box by means of a plug-in connection through the aperture of the switch face plate. According to one aspect of the invention, a programmable electronic timer-switcher comprises a mounting plate which is secured to the opening of the wall switch box. A multiple-conductor receptacle is secured to the mounting plate, which also preferably serves as a heat sink for a switching means such as a triac. The receptacle is aligned behind the rectangular aperture of a standard switch face plate to permit plug-in connection to a programmable electronic timer disposed exteriorly of the face plate. The switching means and the timer cooperate to effect controlled energization of the electrical light or appliance. According to other aspects of the present invention, appliance timer-switches are adapted for engagement with standard electrical outlets and connection to electrical appliance cords.
