    摘要: A resettable switching apparatus, useful in a GFCI receptacle, has a space-efficient coaxial configuration in which a mechanical latching arrangement for resetting (i.e., closing) main switch contacts 48A,48B is disposed inside the trip solenoid 60. A movable carriage 62 for the main contacts 48A, 48B spans one end of the solenoid 60 and has a latching portion in the solenoid 60 that engages the inner end of a reset plunger 66 in two sequential states (i.e., unlatched and latched). The mechanical latching arrangement comprises a cam surface 72 coupled to a lifting plate 74, which is connected to the carriage 62 of the GFCI receptacle. The cam surface 72 is responsible for translating a downward movement to a translational movement to engage the carriage 62 to the rest plunger 66.
