At this time, the driving assembly may be rotated in a third direction (clockwise direction in fig. 6) or a direction opposite to the third direction. For example, when the driving assembly rotates in the third direction, only the first driving plate drives the first movable contact driving mechanism to rotate.
As shown in fig. 7, when the drive assembly is in the first power position, the first pin 7 abuts the second end wall 62 of the first slot 6 and the second pin abuts the third end wall 91 of the second slot 9. At this time, the driving assembly may rotate in a direction opposite to the third direction (counterclockwise direction in fig. 7). The driving component can not rotate in a third direction due to the blocking of the second movable contact driving mechanism.
As shown in fig. 8, when the drive assembly is in the second power position, the first pin 7 abuts the second end wall 62 of the first slot 6 and the second pin 10 abuts the third end wall 91 of the second slot 9. At this time, the driving assembly may rotate in the third direction (clockwise direction in fig. 8).
