An apparatus includes: a shaft rotatable to a plurality of predetermined positions to change a state of an electric switching device; a motor rotating the shaft via a transmission mechanism when the apparatus operates in an electric operating mode; a braking mechanism configured to brake the motor in response to the shaft rotated to each position when operating in the electric operating mode; a disc coupled to, and rotatable with the shaft, and comprising a plurality of blocking parts and slots therebetween; and a manual lever comprising a rotatable part and a projecting part arranged at an end thereto, wherein in an apparatus manual operating mode, the projecting part is rotatable into the disc via one of the slots when the shaft is located at one of the positions, and slides out from the disc via another slot when the shaft is rotated to another one of the positions.

A device for actuating a rotating shaft selected from a plurality of parallel rotating shafts, comprising a driving shaft supported and actuated by corresponding rotation means, which is provided with a driving gear for the transmission of torque, a plurality of driven shafts each one of which is provided with a corresponding driven gear that is designed to be meshed with the driving gear, the driven gears being arranged on the respective driven shaft in an axial position that is offset with respect to the other driven gears, the driving gear being capable of performing a translational movement axially with means of translational motion for alternate meshing with one of the driven gears, the device further comprising means of prevention of rotation for the driven shafts whose driven gear is not meshed with the driving gear.

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.

A drill motor racking apparatus for remote operation of a circuit breaker is disclosed. The drill motor racking apparatus comprises: a racking adapter, wherein the racking adapter is adapted to be engaged by and secured in a racking mechanism of a circuit breaker; a gearbox having an input and an output; a flexible shaft cable having a first end and a second end, wherein the racking adapter is connected to the first end of the flexible shaft cable and wherein the gearbox is incorporated between the flexible shaft cable and the racking adapter to provide a torque multiplication required to rack the circuit breaker; and a drill adapter adapted to be engaged by and secured in a drill, wherein the drill adapter is attached to the second end of the flexible shaft cable. A method of using the drill motor racking apparatus is also disclosed.

A self-powered recloser includes a circuit breaker, an electrical actuator, an electrical generator, a capacitor, and a lever. When in an on state, the circuit breaker harvests power from a medium voltage line required to actuate its movable contact to interrupt current flow in the medium voltage line, and when in an off state, it does not harvest power from the medium voltage line. The electrical actuator is configured to transition the circuit breaker from the off state to the on state. The capacitor when charged is configured to provide the electrical actuator with the electrical power required to transition the circuit breaker from the off state to the on state. The lever is configured to be moved by an operative. Movement of the lever is configured to charge the capacitor via the electrical generator.

Implementations of the subject matter described herein provide an apparatus for use in a switch. The apparatus includes: a handle including a first slot; a mode button operable to change an operation mode of the switch, the mode button including a second slot; a slider coupled to the mode button and movable in a first direction in association with a movement of the mode button, the slider including a first block; a lever operable to be opened in a rotatable manner and including a pin, wherein when the mode button is set at a service position, the first block is received in the first slot to maintain the handle; and in response to the lever being opened in the rotatable manner, the pin is operable to pass through the second slot to prevent the movement of the mode button. Such apparatus herein provides a lock mechanism that may prevent mistake operation between different operation modes.
