Abstract: A power control apparatus in the form of a standard, toggle, wall-mounted light switch for remote actuation of an electrical load or local manual override. A switch housing supports and retains a latching relay that includes power terminals, a switching terminal for remote actuation by a control signal, and a manual override. A switch lever extends from the body of the switch housing for manual actuation to override the state of the relay. The switch lever engages the manual override of the latching relay upon manual actuation by a person. A centering structure maintains the switch lever in a centered position to allow unimpeded movement of the manual override. The latching relay can be remotely actuated by a signal at its switching terminal to switch a power load connected to the power terminals on or off, or the relay can be manually overridden by actuation of the switch lever.

Abstract: A lever arm assembly is provided for a circuit breaker trip actuator reset assembly including a cradle assembly pivotably coupled to the circuit breaker pole shaft, a reset lever pivotably coupled to the circuit breaker housing, and a trip actuator including an actuating element, which moves the reset lever in response to a trip condition. The lever arm assembly includes at least one linking element including a first end pivotably coupled to the cradle assembly, a second end, a pivot, and a deflection assembly having a deflection member. When the cradle assembly moves from a first position toward a second position, it moves the linking element, thereby moving the deflection member into engagement with the reset lever. This pivots the reset lever to reset the trip actuator. After the trip actuator has been reset, the deflection assembly is deflectable to accommodate excess motion of the cradle assembly.

Abstract: An improved ground-fault circuit interrupter (GFCI) receptacle with reverse wiring protection. If the power lines are incorrectly connected to the load end of the receptacle during installation, power output to both the input end of the receptacle and the insertion outlets on the faceplate is prevented. The GFCI receptacle includes two stationary terminals on two first output conductors electrically connected to the insertion outlet, two stationary terminals on two second output conductors adapted for electrically connecting to the load, and four moveable terminal on two moveable connector arm adapted for electrically connecting to the power lines. The four moveable terminals corresponds in position to the four stationary terminals, respectively, and operate to electrical connect or disconnect the power lines to and from the load and the insertion outlet in a manner controlled by a disconnecting mechanism assembly and a reverse wiring protection mechanism.

Abstract: A reset mechanism for a rotary switch, which is manually switchable from a rest position into any desired switch position, for resetting the switch in response to a drop of the electric power supply grid voltage below a predetermined minimum voltage, which includes an electromagnet with an armature, a switching drive shaft including a hand grip section for manually turning the drive shaft into any desired switch position, and a further section having a pinion, shaft sections being freely rotatable relative to each other. A reset device is displaceable transversely to the shaft axis, the reset device including a rack arranged to mesh with the drive shaft pinion and biased by a return spring. A blocking ram is resiliently supported on the armature for displacement in the direction of the shaft axis.

Abstract: The disclosure relates to a resetting device on a rotary switch for resetting the latter when the mains voltage falls below a predetermined limiting value, in which an electromagnet connectable to the power supply and equipped with an armature is provided, and this armature releases or blocks, in dependence on the state of excitement of the magnet, a return mechanism which subjects the rotary switch to a resetting from a switching position into a definite starting position.With such a resetting device, the armature (8) of the electromagnet (7) controls at least one displaceable blocking tappet (13), which blocking tappet, in the case of a switch located in a switching position different from its starting position and with the armature (8) pulled up, rests against a projection (19) or engages into a depression of at least one restoring mechanism (16, 16') loaded by a return spring (21,22) and in drive connection with the drive or switch shaft (1).
