  • Patent number: 9450395
    Abstract: A Ground Fault Circuit Interrupter (GFCI) interrupts the flow of current through a pair of lines extending between a source of power and a load. The GFCI includes a circuit breaker, a relay circuit including a solenoid, a latch circuit, and a fault detecting circuit packaged in a circuit assembly. The GFCI is adaptable for a quick connect of a load input cord by a user, allowing for various configurations of cords to be utilized on site, the cord easily connected from the device being protected to the GFCI at the point of use. The GFCI circuit assembly includes a load input section having cable securement jaws for connection of the load input cable terminal ends.

  • Patent number: 6541723
    Abstract: A rotary switch for an electrical appliance includes a housing adapted to receive a plurality of conductive wires, a plurality of conductive terminals fixedly mounted onto the housing, an actuation shaft rotatably mounted onto the housing, and a movable contact mounted onto the actuation shaft for selectively connecting two of the conductive terminals. The housing includes a base and a cover mounted onto the base. The cover includes a top surface, a bottom surface and a plurality of inwardly tapered guide walls. Each guide wall is shaped to define a slot into which an associated conductive wire can be securely retained in electrical isolation from the remainder of conductive wires. Each guide wall has a funnel-type configuration and includes a closed end and an open end, the slot being narrower at the closed end than at the open end.

  • Patent number: 6130389
    Abstract: A housing for an electric switch includes a recessed base and a cover member. The cover member is constructed to include a hook fastener, a latch fastener, a first pair of clip fingers and a second pair of clip fingers. The hook fastener and latch fastener serve to enable the electric switch to be easily and quickly mounted on a wall in a device with which the electric switch is to be used while the first and second pair of clip fingers serve to hold the hook and latch fasteners tightly in place on the wall of the device when so mounted.

  • Patent number: 5913574
    Abstract: A cutting module and a cutting element which fits within the cutting module are used to remove polymer, e.g. insulation or a conductive polymer composition, from the first and second electrodes of the cable at the end of the cable in order to make electrical connection from the electrodes to the first and second contact members of an electrical plug. Present within the cutting module are first and second electrode-contact sections positioned on the concave arcuate inner surface of the wall of a cavity in the cutting module. The electrode-contact sections can be electrically connected to the first and second contact members. The cutting element comprises a cutting wedge which has (a) a convex arcuate outer surface which complements the inner surface of the wall of the cutting module, and (b) piercing means suitable for penetrating the polymer.

  • Patent number: 5750947
    Abstract: A rotary electric switch having push-in wire terminals includes a hollow plastic housing having a recessed base and a cover, the base having a plurality of wire receiving openings. A plurality of resilient stationary contacts are positioned in the base, each resilient stationary contact being generally Z-shaped and having a locking tongue at one end, an intermediate arm, and a spring finger at the opposite end from the locking tongue. Each resilient stationary contact is positioned in the base with its locking tongue overlying a wire receiving opening in a side wall in the housing. A rotatable contactor is mounted in the base between the spring fingers of the resilient stationary contacts.
