  • Patent number: 5781387
    Abstract: A new and novel system for protecting people and property against electrical shock. It includes a number of preferred and other embodiments which have this as their goal, but which represent a number of distinctive and novel approaches to solving prior art problems. By way of example only, and without limiting the scope of this invention, these approaches include novel immersion detecting circuits, broken wire test circuits, electromechanical circuit breaking including coil/plunger arrangements, and relay circuit breaking mechanisms cooperative with associated circuitry, all of which are able to be incorporated as a system wholly within the load (appliance) and its associated cord set (including a "plug").
    Type: Grant
    Filed: July 24, 1996
    Date of Patent: July 14, 1998
    Assignee: Leviton Manufacturing Co., Inc.

  • Patent number: 4595894
    Abstract: A switching system for interrupting an electrical circuit is described. This switch includes a number of preferred and other embodiments which have this as their goal, but which represents a number of distinctive and novel approaches to solving switching problems in the prior art. By way of example only, these approaches include provision of mounting strap which supports ground terminals while also serving as a magnetic circuitry conduit; a "banger" type arrangement which enables alternate making and breaking of a circuit; and a space-saving method for supporting the arrangement within a device or system able to be installed within a conventional receptacle box.

  • Patent number: 4518945
    Abstract: The present invention teaches a remote control system, also capable of designation as a universal switch receptacle system, which is usable in conjunction with remote control devices as well as ground fault circuit interrupting systems. Features include, without limitation, a mounting strap which supports ground terminals while also serving as a magnetic circuitry conduit; a novel flip-flop cam arrangement which enables alternate making and breaking of a circuit; and space-saving means for supporting the cam arrangement about an axis of rotation which coincides with a ground prong insertion axis.

  • Patent number: 4284317
    Abstract: An angle cap electrical wiring connector contains a cable clamp which is removably fixedly mounted to the angle cap housing independent of the clamp tightening screws. The clamp includes an arcuate section which completes the circular cavity wall of the angle cap body housing the electrical wiring chamber. An expandable diaphragm extending between the arcuate section and the clamp closes access to the wiring chamber from the environment at all times, regardless of size of the power cable clamped to the angle cap. The clamping member, arcuate section and diaphragm are formed integrally as a single piece.
