A terminal shield for a circuit breaker, formed of an electrically insulating material, protects an operator from inadvertently touching the load terminal that would otherwise be exposed on the bottom side of the circuit breaker: In accordance with an example embodiment of the invention, the terminal shield is integrated with a toroidally shaped current transformer sensor, to enable measuring the current in a load wire that has been inserted through an aperture in the terminal shield. Preferably there is an access hole in the front portion of the terminal shield, which allows the operator to insert a tool through the front face of the circuit breaker, to tighten the load terminal onto the load wire. The terminal shield with the integrated current transformer sensor enables standardization of load current sensing capability for circuit breakers and further enables ease of installation without clutter in the confined regions of the load center.

Disclosed is a suspensible external combined on-load tap changer, including: a switch box, a switch body and a motor mechanism, a top box wall of the switch box being opened with a top opening, a top box cover being mounted on the top opening, wherein the switch body is detachably mounted in the switch box and is entirely lifted in and lifted out by the top opening; and the motor mechanism is connected with the switch body in a driving manner. The switch body in the present invention uses a hoisting structure, and the top box wall of the switch box is opened with a top opening with a size large enough, so that the switch body is directly lifted in and lifted out of the switch box from the top opening, and installation and maintenance are easier.

A contactor mounting system is disclosed herein. The contactor is directly mounted to the printed wire board. Pins may be coupled to an exposed end portion of the first stationary lead and the second stationary lead of the contactor. Pins may be configured to interconnect the contactor to the printed wire board.

A control module for an electric switch comprising: a body part, a main control shaft, an operating shaft and a drive system operationally connecting the main control shaft to the operating shaft such that the operating shaft is adapted to be rotated by the main control shaft. Rotation axes of the main control shaft and operating shaft are perpendicular to each other. The body part comprises a first side wall, a second side wall, a top wall and a bottom wall. The bottom wall is provided with a bottom recess adapted to receive a portion of an add-on, a bottom part of the main control shaft being accessible through the bottom recess.

The present disclosure relates to a button structure and a display device having the button structure. The button structure includes a housing, a function control substrate, a mechanical button and a remote control module. The housing has a reception space and a connection structure, is detachably connected to an electronic device through the connection structure, and has an installation surface to be docked to the electronic device, the installation surface is provided with a cable hole which communicates with the reception space, the electronic device is provided with a hole corresponding to the cable hole. The function control substrate is provided within the reception space and is connected with a cable, which extends into the electronic device via the cable hole and the hole and is connected to an electronic element inside the electronic device.

A switching module for a switch includes a housing configured to execute a switching movement when the switch is actuated. The switching module also includes an actuator, which is disposed in the housing and is configured to execute an actuation movement that can be controlled by a control contour. Moreover, the switching module includes an energy converter, which is disposed in the housing and is configured to provide an electrical pulse when powered by the actuation movement of the actuator. Furthermore, the switching module includes a switch unit for emitting a switching signal based on the electrical pulse, for indicating the switching movement of the housing.

Power switch manipulation apparatuses that allow users to manipulate power switches of FRUs mounted within storage racks in a manner free of a user having to physically reach into the storage rack to manipulate the power switches. One embodiment of the disclosed manipulation apparatus broadly includes a base member that may be rigidly secured to a portion of the frame of a storage rack (e.g., on a side or vertical member adjacent a rear door or opening of the rack at the same or similar height as at least one of the power switches) along with a tool that is movably mounted or mountable to the base member for manipulating a power switch of a FRU mounted in the rack.

A wire connection accessory is disclosed that includes a mounting structure formed thereon configured to mate with an existing mounting feature provided on a “host” electrical switching component or “host” operator switch present within an electrical enclosure/assembly is disclosed. The wire connection accessory comprises a component whose mechanical and electrical state does not change response to functioning of the host device to which it is mounted. The host electrical switching component or operator switch includes a first mounting feature formed on an external surface thereof so as to serve as a host device. The wire connection accessory includes a second mounting feature mateable with the first mounting feature to selectively affix the wire connection accessory to the host device.

An electrical short-circuiting closing switch including an electrically insulating housing; a first electrode having a tapered first electrode opening; a second electrode having a tapered second electrode opening; a movable contact having a tapered profile, the movable contact being movable relative to the housing along a closing axis from an open position, in which the movable contact is electrically disconnected from the second electrode, to a closed position, in which the movable contact electrically connects the first electrode and the second electrode by engaging the tapered profile with the first electrode opening and the second electrode opening; and an actuator arranged to force the movable contact from the open position to the closed position; wherein at least one of the first electrode and the second electrode is flexibly attached to the housing. A switchgear including a closing switch is also provided.
