Abstract: The invention relates to an electronic/electrical connecting arrangement (2) with a first housing part (28) and a second housing part (30), which can be brought along an assembly axis (M1) into a connecting position in which they form a first connection contour (41), which is connectable to the first contacting element (4), and a second connection contour (50). A connecting conductor (22) is received in the housing of the connecting element (8), the connecting conductor having first contacting means (24) on the first connection contour (41) that can be brought into electrical/electronic contact with the first conductor (10) in a first contact plane (KE1), and second contacting means (26) on the second connection contour (50) that can be brought into electrical/electronic contact with the second conductor (20) in a second contact plane (KE2) different from the first contact plane (KE1).

Abstract: A secure switch module to allow only authorized keyholders to power on an electronic device includes a lock, a key matching the lock, and a power switch. The lock includes a first lock pin electrically connected to a ground pin of a motherboard of the electronic device, and a second lock pin. The power switch includes a button, a first elastic conductive sheet electrically connected to the second lock pin, and a second elastic conductive sheet electrically connected to a power on pin of the motherboard. When the key is engaged with the lock and the button is pressed, the first lock pin is electrically connected to the second lock pin, the first elastic conductive sheet is electrically connected to the second elastic conductive sheet, the power on pin receives a low level signal, and the electronic device is turned on.

Abstract: A mechanical interlock socket outlet includes a female receptacle mounted to a face plate, a breaker box, a toggle switch for activating the breaker box, and an actuating rod for operating the toggle switch. A locking arm is provided for engaging the actuating rod and has a first position and a second position. A safety release saddle plate is engaged to the actuating rod. The plate has a locking arm release portion such that movement of the plate will contact the locking arm and move the locking arm from the first to a second position. Springs are connected between the plate and the face plate, and connected to a portion of the saddle plate adjacent a top portion of the plate. The springs act to return the saddle plate and toggle switch to a locked position. A push pin is provided to move the saddle plate.

Abstract: An arc fault circuit breaker includes a panel having a first side and an opposite second side, a housing coupled to the opposite second side of the panel, separable contacts, an operating mechanism structured to open and close the separable contacts, and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a test circuit structured to simulate a trip condition to trip open the separable contacts, and a proximity sensor disposed on or within the housing proximate the opposite second side of the panel. The proximity sensor is structured to sense a target to actuate the test circuit when the target is disposed proximate the first side of the panel and opposite the proximity sensor.

Abstract: An operating mechanism, for a switch of a switching device disposed in a control cabinet having a door, includes a locking device having a locking element movable between a release position and a locking position. A spring device is configured to bias the locking element toward the release position. A force-transmitting member is operatively coupled to a resilient control member of the door, the force-transmitting member being configured to actuate the locking element.

Abstract: A receptacle including a front surface including one or more slots for receiving contact blades; a rear surface including one or more terminals for connecting the contact blades to a power source, the one or more terminals being line terminals and load terminals; a shutter positioned between the front surface and the rear surface of the receptacle, the shutter configured to be misaligned in relation to the one or more slots in order to obstruct a direct path between the contact blades and the one or more terminals, wherein insertion of an object in the one or more slots causes displacement of the shutter; and a shutter lock operatively connected in the receptacle to receive power from the power source connected to the receptacle.

Abstract: The present invention is a thermally activated electrical switch for use in simulating human activity. The invention is features dual heat sources enclosed in a thermally isolated chamber within the invention. Since the activation of the switch is dependent upon the ambient temperature of the environment, it opens and closes at sufficiently random intervals to simulate human activity. This embodiment includes the use of a photoelectric sensor to further vary timing of the switch actuation.

Abstract: The automatic locking and releasing structure for a push-pull plug of this invention includes an upper case, a bottom case, a slider and push-buttons. The bottom case is suspended therein with two symmetrically arranged slide tracks that are each provided at the inside thereof with a wedge piece. The opposing sides of the slider are each formed with a resilient retaining arm, and the slider is movably provided between the two slide tracks. The free ends of the resilient retaining arms are movably attached to the push-buttons provided at the outside of the slide tracks. As such, when one manipulates the push-buttons to move along slide slots formed in the upper case and bottom case, the slider may be retracted or extended at the same time thereby subjecting the resilient retaining arms to assume a locking or releasing state with respect to the wedge pieces.

Abstract: A blocking member located within the body of the GFCI is positioned by the reset button to allow free access of the prongs of a plug into the openings of the receptacle when the reset button is depressed or to block at least one opening of the receptacle to prevent a plug from entering the openings of the receptacle when the reset button projects out beyond the surface of the housing. Thus, when the GFCI is in a conducting state, the reset button is recessed within the GFCI housing and positions the blocking member to the first position to allow the prongs of a plug to be inserted into the receptacle openings. When the GFCI is in a non-conducting state, the reset button protrudes outward from the housing of the GFCI to position the blocking member to the second position to block at least one opening of the receptacle to prevent the prongs of a plug from entering the receptacle.
