On an insulating baseboard with a central opening there are located contacts. There are also auxiliary contacts intended for connecting local control circuits of the device. A rotational electromechanical drive is provided to rotate a contactor, and an electromagnetic drive is adapted to reciprocate said contactor for operating contacts. The electromagnet drive has an electromagnet for closing contacts and a plurality of electromagnets for opening contacts. The number of the electromagnets corresponds to the number of the contact fixing devices. The armature of each electromagnet is connected with one of the contact fixing devices.

Power electric circuit switching device

An electric circuit switchgear includes main contacts circumferentially arranged on a fixed panel and auxiliary contacts. The switchgear also includes a rotary electromechanical drive connected with a driving shaft and enabling the latter to be turned through a pre-set angle. The driving shaft is rotated together with an actuating element of an electromagnetic drive provided with a contactor and a disconnector both having at least one projection interacting with the main and auxiliary contacts through contact closing and disconnecting mechanisms having locks.
