Rapid switching mechanism of dual power changeover switch

The invention relates to a rapid switching mechanism of a dual power changeover switch. The rapid switch mechanism comprises a mechanism body, the two ends of the mechanism body are provided with a solenoid A and a solenoid B respectively, the middle portion of the mechanism body is provided with a rotating shaft, one end of the rotating shaft is connected with a power spring A and a power spring B of the mechanism body, the power spring A and the power spring B are arranged at the two sides of the rotating shaft respectively, the other end of the rotating shaft is connected with a movable rod, the rotating shaft is integrated with the movable rod, a movable iron core sleeves the rotating shaft, and the movable iron core can drive the rotating shaft to move horizontally. The mechanism is simple in structure, convenient to assemble, and high in switching speed, is prevented from being stuck, and does not influence the arc extinguishing performance.
