Abstract
The invention relates to electric engineering and may be used as a phase sequence switch for control of reversible electric loads or two-speed electric motors. A device comprises at least one pair of vacuum extinguishing chambers and a magnetic actuator, a movable armature of which is connected to a lever mechanically connected to movable contacts of vacuum extinguishing chambers in such a way that when contacts of first extinguishing chamber of every pair are open, contacts of the second extinguishing chambers are closed and otherwise - when contacts of the first vacuum extinguishing chamber of every pair are closed , contacts of the second vacuum extinguishing chamber are open. Every fixed contact of the vacuum extinguishing chamber is connected to busbar fixed on the basis. It is proposed, fixed contacts of every pair of the vacuum extinguishing chamber are fixed to busbars located on the both sides of the insulation panel installed on the basis. Movable contacts of the vacuum extinguishing chamber are mechanically connected to the drive lever capable of their movement relative to the lever to close with fixed contacts with engaged position of an electromagnet, all movable contacts to connect at the same time to the conductor line having a terminal connected to one phase of the power source, all open at the same time contacts to connects to the second conductor line having terminal connected to the other phase of the power source. The invention allows simplifying a construction and enhancing the reliability of device operation.
