When the operating mechanism needs to perform a normal (first power supply) closing operation, the main electromagnet 11 is energized to move the plunger 12 from the first position to the second position, and drive the first driving arm 21 and the second driving arm 22 to move downward together, so that the driving surface 2011 on the driving end 201 on the first driving arm 21 abuts against the first driving shaft i 41 on the left side on the rotating disc 4, and the rotating disc 4 is driven to rotate counterclockwise by an angle in the first direction, thereby achieving the normal closing operation, as shown in fig. 1b, in this process, as the second driving arm 22 deflects by an angle, the hinge shaft 2021 moves in the inner measuring chute 331, the limiting shaft 23 moves in the outer chute 333, and the second driving arm 22 is disengaged from the first driving shaft ii 41 'on the right side and the second driving shaft ii 42' on the right side on the rotating disc 4.

The course of action is similar to that described above.

The method comprises the following specific steps: as shown in fig. 2a, the main electromagnet 11 is located at the first position, the operating mechanism is located at the common driving side, that is, the selective moving iron core 32 is located at the first selection position, at this time, the first driving arm 21 is located at the working position, and the second driving arm 22 is located at the non-working position, unlike embodiment 1, the first driving arm 21 and the second driving arm 22 realize the switching between the working position and the non-working position through the translational sliding, at this time, the double-division position, when the common (first power supply) is required to be closed, the main electromagnet 11 is energized, the moving iron core 12 moves downward, the driving plate 13 is driven downward, so that the driving surface 2011 on the first driving arm 21 drives the first driving shaft i 41 on the left side of the rotating disc 4, the rotating disc 4 is driven to rotate counterclockwise by an angle in the first direction, when the moving iron core 12 reaches the second position, the switch reaches the common closing position, as shown in fig. 2b, after the operation is completed, the main electromagnet 11 is de-energized, the movable iron core 12 returns from the second position to the first position under the action of the main return spring 14 inside the main electromagnet 11, and drives the driving plate 13, the first driving arm 21 and the second driving arm 22 to return from the second position to the first position, in the process, the first driving arm 21 is in the working position, and the second driving arm 22 makes the second driving arm 22 in the non-working position due to the pushing of the selective movable iron core 32 and the matching of the limiting shaft 23 at the side of the second driving arm 22 and the sliding slot 131, as shown in fig. 2 c.

When the normal power supply needs to be switched to the standby power supply, the switch needs to be switched to the double-split position first, the selection electromagnet 31 is powered, as shown in fig. 2d, the selection movable iron core 32 moves leftwards to push the first driving arm 21, the sliding shaft 2022 of the first driving arm 21 overcomes the elastic resetting mechanism 34 in the sliding chute 131, in this embodiment, the elastic resetting mechanism 34 is a compression spring arranged in the sliding chute, the sliding shaft 2022 of the first driving arm 21 moves leftwards, the first driving arm 21 is switched from the working position to the non-working position, that is, the driving end 201 of the first driving arm 21 is away from the driving position matched with the rotating disk 4, and simultaneously, due to the release of the selection movable iron core 32 to the second driving arm 22, the second driving arm 22 is switched from the non-working position to the working position under the action of the elastic resetting mechanism 34 on the side, that is translated leftwards relative to the driving plate 13, so that the driving end 201 of the second driving arm 22 reaches a driving position in which it engages with the right second driving shaft ii 42' on the turntable 4. After the selection electromagnet 31 is energized, the main electromagnet 11 is energized, and the movable iron core 12 thereof drives the driving plate 13 to move from top to bottom, and the driving surface 2011 of the second driving arm 22 pushes the second driving shaft ii 42' on the right side, so that the rotating disc 4 rotates clockwise through the first angle to reach the switch double-division position, as shown in fig. 2 e.

When the main electromagnet 11 is de-energized and the selective electromagnet 31 is de-energized at the same time, the driving plate 13 drives the first driving arm 21 and the second driving arm 22 to move from the second position to the first position, in the process, the second driving arm 22 located at the working position is pushed by the first driving shaft ii 41 'on the right side due to the first driving shaft ii 41' on the right side arranged on the moving path, so that the second driving arm 22 overcomes the spring force of the elastic resetting mechanism 34, slightly translates to the right in the sliding chute 131, avoids the first driving shaft ii 41 'on the right side, until the driving surface 2011 of the second driving arm 22 crosses the first driving shaft ii 41' on the right side, the second driving arm 22 is restored under the action of the elastic resetting mechanism 34, but at this time, the selective electromagnet 31 is de-energized, the selective movable iron core 32 moves to the right under the action of the selective resetting spring 30, the selective movable iron core 32 pushes the second driving arm 22 to overcome the spring force of the elastic resetting mechanism 34 to enter the non-working position, at this time, due to the loss of the pushing action of the selection movable iron core 32, the first driving arm 21 enters the working position from the non-working position under the action of the spring force of the elastic return mechanism 34 on the same side as the first driving arm, that is, the driving end 201 of the first driving arm 21 reaches the driving position matched with the first driving shaft i 41 on the left side of the turntable 4, as shown in fig. 2f, and the switch is at the double-split position at this time.
