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 actuator 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, which is a double-split position, when the common (first power source) is required, the main electromagnet 11 is energized, the actuator 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 turntable 4, the turntable 4 is driven to rotate an angle in the counterclockwise direction in the first direction, when the actuator 12 reaches the second position, the switch reaches the common closing position, as shown in fig. 2b, the actuation is completed, then the main electromagnet 11 is de-energized, the actuator 12 is driven from the second position to the first closing position under the action of the main reset spring 14 inside the main electromagnet 11, the actuator 12 drives the driving plate 21, the second driving arm 21 and the second driving arm 22 to the second closing position, and the second actuator arm 22 is pushed and the second actuating arm 22 is located at the second position, as shown in the working position, and the second slide slot 2c, which is pushed and the selective actuator arm 22.

When a common power supply needs to be switched to a 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 groove 131, in this embodiment, the elastic resetting mechanism 34 is a compression spring arranged in the sliding groove, 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 turntable 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 the driving position matched with the second driving shaft ii 42' on the right side 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 selection 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 this process, the second driving arm 22 located at the working position is pushed by the right first driving shaft ii 41 'due to the right first driving shaft ii 41' 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 chute 131, avoids the right first driving shaft ii 41', until the driving surface 2011 of the second driving arm 22 passes over the right first driving shaft ii 41', the second driving arm 22 returns under the action of the elastic resetting mechanism 34, but at this time, the selection electromagnet 31 is de-energized, the selection electromagnet 32 moves to the right under the action of the selection resetting spring 30, the selection electromagnet 32 pushes the second driving arm 22 to enter the non-working position overcoming the spring force of the elastic resetting mechanism 34, and at this time, due to the pushing action of the selection electromagnet 32, the first driving arm 21 reaches the non-working position from the first driving end, i.e. the first driving arm 21 and the driving end of the first driving switch 2, which is matched with the first double-side driving switch 21 as shown in the drawing.

In the standby switching-on position, if the switch needs to be switched off, the main electromagnet 11 is energized, the left first driving arm 21 is in the working position and is pulled by the driving plate 13 to move from the upper first position to the lower second position, the driving surface 2011 on the driving end 201 of the first driving arm 21 pushes the left second driving shaft i 42 on the rotating disc 4 to drive the rotating disc 4 to rotate counterclockwise by a first angle to reach the double-split position, as shown in fig. 2 j. Next, the main electromagnet 11 is de-energized, the movable iron core 12 drives the first driving arm 21 and the second driving arm 22 to return to the upper first position from the lower second position through the driving plate 13, in this process, similarly, since the first driving arm 21 is in the working position, the left first driving shaft i 41 on the turntable 4 is in the motion path of the driving end 201 of the first driving arm 21, and the reset surface 2012 thereon is pushed by the first driving shaft i 41, so that the first driving arm 21 moves leftward, that is, the sliding shaft 2022 of the first driving arm 21 moves leftward in the sliding chute 131 against the spring force of the elastic reset mechanism 34 on the same side, as shown in fig. 2k, so that the driving end 201 of the first driving arm 21 retreats past the left first driving shaft i 41, and when the driving surface 2011 on the first driving arm 21 passes past the left first driving shaft i 41, the first driving arm 21 returns to the working position under the action of the elastic reset mechanism 34, as shown in fig. 2 a.

At this time, when the main electromagnet 11 is energized, the movable iron core 12 moves from the first position to the second position, pulls the first driving arm 21 to move downward, and the driving surface 2011 on the driving end 201 of the first driving arm 21 pushes the left first driving shaft i 41 on the turntable 4, so that the turntable 4 rotates counterclockwise by a certain angle in the first direction, thereby implementing the closing of the common power supply, as shown in fig. 3 b. After the closing operation is completed, the main electromagnet 11 is reset, i.e. returned from the second position to the first position, and drives the first driving arm 21 to return from the lower position to the upper position, as shown in fig. 3 c.
