Abstract: A bidirectional operation mechanism for a switching device and a switching device assembly. The bidirectional operation mechanism includes: a housing; an operation handle; a first driving member, rotatably installed to the housing, fixedly connected to the operation handle; a second driving member, rotatably installed to the housing, operatively connected to the first driving member and the switching device, upon an external force acting on the operation handle to drive the operation handle rotate between the closed position and the open position, the operation handle drives the first driving member to rotate together, so that the first driving member abuts against and drives the second driving member to rotate, enabling the switching device to perform a closing operation and an opening operation.

Abstract: Embodiments of the present disclosure provides a motor starter, the motor starter includes a housing including a base plate; power supply board disposed on the base plate; a first insulating board covering a side of the power supply board away from the base plate; a signal processing board disposed on a side of the first insulating board away from the base plate, and a first insulating part is disposed on a side of the signal processing board away from the base plate; and an interface board disposed on a side of the signal processing board away from the base plate, and a second insulating part is disposed on a side of the interface board facing the signal processing board, a second insulating board is disposed on a side of the interface board away from the signal processing board.

Abstract: The present disclosure relates to an electromechanical sequential action device that is capable of sequentially interlocking a mechanical switch and a power electronic switch, where through an action sequence control, the electromechanical mechanism turns on the power electronic switch only after the mechanical switch is closed, and through an advanced travel control, turns off the power electronic switch before opening the mechanical switch, avoiding the problem of arc discharge during closing and opening of the mechanical switch, and improving the service life and connection reliability of the mechanical switch.
