Working principle:

1. And (3) manual control: the operator inserts the hexagonal groove 503 through the hexagonal wrench 10, and the manual rotation part 501 is manually operated to drive the manual gear 502 to rotate clockwise, and the manual gear 502 drives the linkage plate 7 to move backwards, so that the push plate 704 pushes the switch contact 2 to perform manual closing operation; the manual rotation part 501 is manually operated to drive the manual gear 502 to rotate anticlockwise, and the manual gear 502 drives the linkage plate 7 to move forwards, so that the push plate 704 pushes the switch contact 2 to perform manual opening and closing actions.

2. Automatic control: the operator is electrically connected with the built-in controller through the remote controller, and the remote control driving motor 602 rotates forward, so that the driving motor 602 drives the driving gear 601 to rotate clockwise, and the driving gear 601 drives the linkage plate 7 to move backwards, so that the push plate 704 pushes the switch contact 2 to perform automatic closing action; the remote control driving motor 602 reverses, so that the driving motor 602 drives the driving gear 601 to rotate anticlockwise, and the driving gear 601 drives the linkage plate 7 to move forwards, so that the push plate 704 pushes the switch contact 2 to perform automatic opening and closing actions.

3. When the manual operation member 5 is not in use, the damper 801 shields the hexagonal recess 503 at the upper end of the manual rotation portion 501, and the operator cannot use the manual rotation portion 501, and at this time, the automatic operation member 6 controls the opening and closing operation of the switch contact 8042. If the circuit breaker needs to be manually operated, the starting head 8021 needs to be pressed down firstly to enable the connecting pin to be separated from the pin groove, then the starting head 8021 is rotated to enable the starting head 8021 to drive the moving body 8022 to rotate, the moving body 8022 acts on the interaction part 803 to enable the interaction part 803 to move, so that the through hole A8011 is moved to the right upper end of the manual rotation part 501, the hexagonal groove 503 of the manual rotation part 501 is exposed, and further the manual operation is performed; while the interaction part 803 moves, the interaction part 803 also triggers the switch part 804, so that the driving motor 602 no longer acts on the driving gear 601, and an interlock is formed.
