    摘要: A resettable switching apparatus, useful in a GFCI receptacle, has a housing with a face plate and at least one sense transformer core positioned to define a current flow direction through a center cavity that is parallel to the face plate. The GFCI receptacle further includes a space-efficient coaxial configuration in which a mechanical latching arrangement for resetting (i.e., closing) main switch contacts is disposed inside the trip solenoid. A movable carriage for the main contacts spans one end of the solenoid and has a latching portion in the solenoid that engages the inner end of a reset plunger in two sequential states (i.e., unlatched and latched). The mechanical latching arrangement comprises a cam surface coupled to a lifting plate, which is connected to the carriage of the GFCI receptacle. The cam surface is responsible for translating a downward movement to a translational movement to engage the carriage to the rest plunger.

    摘要: An electrical wiring device, such as a GFCI duplex receptacle, includes a light source for lighting a selected area and a photo sensor to detect ambient light conditions and to actuate a light source when the ambient light conditions are below a predetermined level. The light source is preferably at least two LEDs having an associated light conducting member functioning as a light pipe that extends between the respective LED and the front face of the electrical wiring device. Each light conducting member has an inclined face extending through an opening in the cover of the wiring device to project a light beam at an inclined angle with respect to the front face of the wiring device. The light conducting members are independently rotatably mounted in the wiring device so that the user can manually rotated the light conducting member to direct the light beam to a selected area.
