  • Patent number: 4323762
    Abstract: Apparatus for disconnecting electrical powered devices from a source of electrical energy when the use of the devices is no longer needed. The apparatus includes an electrical switch movable in response to an actuation member. The switch is connected between a source of electrical energy and an electrical powered device so as to selectively connect/disconnect the device to the source of electrical energy depending upon the use of the actuation member. A second electrical switch, also responsive to the actuation member, is connected between the source of electrical energy and another electrical powered device, such as a heating/air conditioning unit, to connect/disconnect the heating/air conditioning unit to the source of electrical energy. One temperature responsive device is associated with the second electrical switch in order to maintain the room temperature above a predetermined minimum temperature.
