To achieve the same rotational direction as the energy storage device 80, the present invention incorporates an output reversing shaft assembly. The second crank arm 40 on the reversing shaft 67 realizes the purpose of reversing the rotation direction of the output shaft through the transmission of the connecting plate 69.

When the closing electromagnet is switched on, the closing electromagnet is caused to drive the closing device 48 to release energy, and closing is completed. At this time (see fig. 1), the third crank arm 139 on the reversing device drives the fourth crank arm 137 on the auxiliary switch through the connecting rod 129 to drive the auxiliary switch 77 to cut off the power supply. For each actuation of the auxiliary switch, the tension spring 134 pulls the counter 88 once. Similarly, when the switching electromagnet 6 is turned on, the switching device 55 is released, and the counter is not operated.

(2) The switching-on button device and the switching-off button device are identical in structure and comprise a switching-on button 120, a switching-on reset spring, a switching-on inclined plate 117, a switching-on roller 118 and a switching-on lever 119, wherein one end of the switching-on reset spring is arranged on the switching-off button, the other end of the switching-on reset spring is arranged on the fixing base, the switching-on inclined plate is arranged on the switching-on button, one end of the switching-on lever is connected to the switching-on position of the switching-on device, the other end of the switching-on lever is connected with the switching-on roller, the switching-on roller is located below the switching-on inclined plate, and the switching-on lever swings through pressing the switching-off button.
The operating principle is that when the button 110 is pressed inwards, the inclined plate 111 on the button pushes the roller 114 to slide downwards, and the lever in the middle of the roller releases the brake release device. After the action is completed, the spring 65 resets the button device and the closing button device is similarly operated.
Regarding the reclosing preventing device, the reclosing preventing device includes a flexible push rod 71 and a limiting rod 73, the output shaft has an extension mounting portion 38-1 mounted on the rear plate, the other end portion 38-4 of the output shaft is mounted on the front plate, the flexible push rod 71 is mounted on the extension mounting portion of the output shaft and rotates with it, the other end of the flexible push rod 71 is connected to one end of the limiting rod 73, and the reclosing device has a shaft end.
