A compact inline unitized plug/receptacle adapter interconnects a four blade plug configuration with a three slot receptacle thereby allowing a boat or RV user to readily adapt to an available receptacle at mooring or camping sites while retaining the ability to utilize the electrical equipment therein. The adapter includes a cover assembly carrying on the outer end the three blades for connection with a host receptacle and carrying on the inner end the four terminals for connection with the guest plug. The live or hot terminals are interconnected by a jumper bus mounted at a raised pad on the cover and electrically connected with the live blade. The neutral and ground terminals are separately connected with their respective blades and mounted at pads of differing elevation on the cover thereby providing differing base elevations and a first degree of physical and electrical insulation between the hot and neutral/ground paths. The adapter includes a housing having a cavity provided with walled surfaces forming separate insulating pockets for aligning the individual terminals with slots for accepting the four blade guest plug. The pockets physically and electrically laterally separate the terminals to provide a second degree of physical and electrical insulation between the terminals.

A miniature appliance leakage current interrupter (ALCI) interrupts the flow of current through a pair of lines extending between a source of power and a load. The ALCI comprises a circuit breaker having a pair of normally closed switches, one switch being located in each of the pair of lines between the source of power and the load. The circuit breaker is connected to a relay circuit which selectively opens the pair of normally closed switches. The relay circuit is connected to a fault detection circuit which detects the presence of a ground fault condition in the pair of lines. When the ground fault condition detected exceeds a predetermined value, an integrated circuit chip in the fault detection circuit causes the relay circuit to open the circuit breaker. The ALCI further includes a housing having a top, a bottom, a front end and a rear end. A prong assembly for supplying power from the source of power to the remainder of the ALCI is in line mounted on the housing. In one embodiment of the present invention, the housing is permanently mounted on an electrical cord connected to the load and the prong assembly includes a line contact prong and a neutral contact prong. In another embodiment of the present invention, the housing is constructed so that it can be removably mounted on an electrical cord connected to the load and the prong assembly includes a line contact prong, a neutral contact prong and a ground contact prong.

A rotary electric switch having push-in wire terminals includes a hollow plastic housing having a recessed base and a cover member. The cover member comprises a top surface, a bottom surface and an annular boss which is shaped to define a central bore. A plurality of resilient stationary contacts are positioned in the base. A switch handle is rotably mounted on the base between the plurality of resilient stationary contacts. The switch handle comprises a disc-shaped rotor having a top surface and a bottom surface. The switch handle further comprises an elongated shaft and an arcuate rotor stop which are formed on its top surface, the elongated shaft protruding through the central bore in the cover member and the arcuate rotor stop being disposed within a rotor recess formed in the bottom surface of the cover member. A rotatable contactor is mounted on the bottom surface of the rotor of the switch handle and serves to selectively contact the stationary contacts. A coiled wire is mounted on the top surface of the rotor and is held in a pre-loaded position by the rotor stop, the coiled wire being disposed within a coiled wire recess formed in the bottom surface of the cover member. In use, rotation of the switch handle causes the rotatable contactor to selectively contact the stationary contacts in such a manner so as to provide the switch with a plurality of different settings, such as a momentary setting, an off setting and low and high power stable state settings.
