A permanent magnet drive on-load tap-changing switch including a changing switch circuit and a high-speed mechanism. The circuit includes structurally identical odd and even-numbered tap-changing switch circuits. The mechanism includes a traveling mechanism used for bearing a moving contactor, a moving magnet group connected with the traveling mechanism, and a fixed magnet group producing an attracting/repelling force with respect to the moving magnet group. The moving magnet group includes a first and second permanent magnet connected at homonymic magnetic poles. An exposed homonymic magnetic pole of the first and the second permanent magnet face directly the fixed magnet group. The fixed magnet group includes a rotating permanent magnet that rotates to change a force applied to the moving magnet group, allowing the moving contactors to either come into contact with or be separated from working contactors and dual-contact synchronous transition contactors.

Systems and apparatuses include an automatic transfer switch including a source pole coupled with a power source, a first load pole coupled with a first load, a second load pole coupled with a second load, a first switch selectively coupling the first load pole to the source pole, and a second switch selectively coupling the second load pole to the source pole.

Disclosed embodiments relate to an electrically controlled switch for high current switching operations and with different configurations of fixed terminal contacts that includes a switch body, a couple of moving contacts, a guide that drives the couple of moving contacts up to an abutting position, a housing groove running perimetric in the switch body, and at least one contact bar for connecting each of the moving contact to a respective fixed terminal contact of the switch, wherein the contact bar is hosted within the housing groove and has a free end projecting from the switch body to form the fixed terminal contact through a corresponding aperture of the switch body located on a same lateral side or on opposite lateral sides, or on the base support, respectively.

A system and method for an automatic transfer switch comprising a fixed contact, a first oscillating rod communicatively and operatively connected to a first movable contact, a second oscillating rod communicatively and operatively connected to a second movable contact, a link rod communicatively and operable connected to the first and second oscillating rods, and a guide plate. The automatic transfer switch is operable to position the guide plate based at least on a state of a solenoid. A permanent magnetic actuator communicatively and operatively connected to the link rod via a third oscillating rod is operable to rotate the first oscillating rod or the second oscillating rod based at least on the position of the guide plate.

A branded fleet server system includes a pre-assembled third-party computer system integrated into a chassis of the branded fleet server system. The pre-assembled third-party computer system is configured to execute proprietary software that is only licensed for use on branded hardware. A baseboard management controller (BMC) included in the server chassis couples with the pre-assembled computer system via one or more cables coupled to ports of the pre-assembled computer system. The BMC enables remote control of the pre-assembled computer system, such as remote power on and power off. An electro-mechanical device, such as a solenoid, presses a power button of the pre-assembled computer system based on control signals from the BMC to change a power state of the pre-assembled computer system.

An electrical short-circuiting device includes a fixed contact piece and a movable contact piece. The fixed and movable contact pieces are distanced from one another in a basic position and electrically conductively connected to one another in a short-circuit position. A drive transfers the movable contact piece from the basic position into the short-circuit position, and a trigger device includes an electrically driven actuator for triggering the drive.

A switching system for switching an electrical device, comprising: a vacuum interrupter including a fixed electrode, and a mobile electrode, the mobile electrode configured to move between a closed position and an open position. The switching system further comprising an elastic return means configured to apply a driving force to the mobile electrode, and a retaining member for retaining the elastic return means, the retaining member configured to moves from a retention configuration, in which the elastic return means is immobilized, into a movement configuration, in which the elastic return means is released. The switching system is configured so that the mobile electrode moves from the closed position to the open position under the action of the elastic return means when the retaining member leaves its retention configuration.

An electrical switch, in particular for high voltages and/or high currents, includes a contact unit which includes at least two contact, a switching element and a drive for the switching element. The drive is designed such that it can move the switching element from an initial position into an end position. The switching element is accelerated during an acceleration phase directly or indirectly by the drive and it passes subsequently through a free movement phase until it has reached the end position.
