A vacuum circuit breaker (VCB) assembly includes a single motor configured to rotate at least one rotor, a VCB having a breaking mechanism configured to control current flow through the VCB and a first electromagnetic clutch configured to selectively engage the at least one rotor with the breaking mechanism to charge the breaking mechanism. The VCB assembly also includes an undercarriage configured to support the VCB assembly and to move the VCB assembly from a first position to a second position and a second electromagnetic clutch configured to selectively engage the at least one rotor with the undercarriage to drive the undercarriage.

The invention relates to an electric switching device (10) for an energy accumulator in an electric vehicle, comprising a housing (20) inside which at least one switching section (30) that includes two input contacts (32a, 32b) and at least one output contact (34) is arranged, and a rotary component (40) which is mounted in such a way as to be rotatable relative to the housing (20) about a switching axis (42) between at least one OFF position (I), a series-connecting position (II), and an ON position (III); said rotary component (40) includes at least one conductor (44) which has at least two conductor contacts (44a, 44b) and which connects the first input contact (32a) in an electrically conducting manner to the output contact (34) in the series-connecting position (II) and connects the second input contact (32b) in an electrically conducting manner to the output contact (34) of the at least one switching section (30) in the ON position (III).

A switch for an electrical circuit includes a base, a rotatable cam having a first profile and a second profile, a solenoid, a link, and a member comprising a cam follower configured to follow the second profile. A first cycle of the solenoid includes a first energized state and a first de-energized state and the second cycle of the solenoid includes a second energized state and a second de-energized state. A first portion of the link couples to the solenoid, and a second portion of the link movably couples to the first profile of the cam. When the solenoid is in a first cycle, the member moves from a retracted position to an extended position, and when the solenoid is in a second cycle, the member moves from the extended position to the retracted position.
