For example, when the button of the third microswitch 33 is pressed, the third feedback circuit is turned on to output the single-tap signal, the button of the third microswitch 33 is reset, and the third feedback circuit is turned off and powered off to be fed back to an external controller as the double-tap signal.

The specific process is that when the normal switch 1 and the standby switch 2 are both in the open state (see fig. 5), at this time, the button of the third micro switch 33 falls into the slot 4232 of the rotary disc 42, the button of the third micro switch 33 is considered to be reset, the third feedback circuit is cut off and power is off to output a double-division signal, when the motor 41 rotates in the forward direction, i.e. clockwise rotation in fig. 5, the first pushing surface pushes the first rocker arm 43 to swing in the direction close to the first micro switch 31 (the closing direction of the normal switch 1), the button of the third micro switch 33 moves out of the slot 4232 and cooperates with the triggering surface 4231 by cooperating with the arc transition surface (i.e. the triggering surface 4231 on the right side in fig. 10), the button of the third micro switch 33 is pressed, the third micro switch 33 switches states, the third feedback circuit is turned on to output a single-division signal, and the handle 11 of the normal switch 1 is closed in place (see fig. 6), the first rocker 43 presses the button of the first microswitch 31 to switch the first microswitch 31, the first feedback circuit is conducted, meanwhile, the second rocker 44 is attached to the second switching surface 4222 but has no interaction force, the standby switch 2 is always in a switching-off state in the switching-on process of the common switch 1, then, through the reverse rotation of the motor 41, the first switching surface 4211 is separated from the first rocker 43 firstly, the first switching surface 4212 pushes the first rocker 43 to swing towards the button direction (the switching-off direction of the common switch 1) far away from the first microswitch 31, in the switching-off process of the common switch 1, the button of the third microswitch 33 is in sliding fit with the arc transition surface on the right side of the clamping groove 4232 and falls into the clamping groove 4232, the button of the third microswitch 33 is matched with the clamping groove 4232, at the moment, the first feedback circuit controlled by the first microswitch 31 is disconnected, the third microswitch 33 is switched, the third feedback circuit is switched from outputting the single-division signal to outputting the double-division signal.

Similarly, when the service switch 1 and the backup switch 2 are both in the open state (see fig. 5), the third feedback circuit outputs a double-division signal, when the motor 41 rotates in the reverse direction, i.e., counterclockwise in fig. 5, the second pushing surface pushes the second rocker arm 44 to swing in a direction approaching the second micro switch 32 (closing direction of the backup switch 2), the button of the third micro switch 33 is moved out of the slot 4232 by cooperating with the arc-shaped transition surface on the left side of the slot 4232 (i.e., the triggering surface 4231 on the left side in fig. 10) and cooperates with the triggering surface 4231 to press the button of the third micro switch 33, the third feedback circuit switches over to output a single-division signal, when the handle 21 of the backup switch 2 is closed in place (see fig. 7), the second rocker arm 44 presses the button of the second micro switch 32 to trigger the conduction of the second feedback circuit, the first rocker arm 43 abuts against the first opening surface 4212 but has no mutual acting force, in the process of switching on the standby switch 2, the normally-used switch 1 is always in a switching-off state, then, the motor 41 rotates in the forward direction, the second switching-on surface 4221 is separated from the second rocker arm 44 firstly, the second switching-off surface 4222 pushes the second rocker arm 44 to swing towards the direction (the switching-off direction of the standby switch 2) away from the button of the second microswitch 32, in the process that the standby switch 2 is switched off in place, the button of the third microswitch 33 is in sliding fit with the arc-shaped transition surface on the left side of the clamping groove 4232 and falls into the clamping groove 4232, at the moment, the second feedback circuit is disconnected, and the third feedback circuit switches output signals, namely, the single-division signals are switched to the double-division signals.

In addition, the opening grooves used as the first pushing portion 421 and the second pushing portion 422 may also include two straight side walls, and the two straight side walls may also be used to mechanically interlock the common switch 1 and the backup switch 2, but the two straight side walls need to have a sufficiently large opening to ensure that the backup switch 2 is in place when the common switch 1 is switched on (or switched off), so that the first switching surface 4211 and the first switching surface 4212 are formed, and the distance between the second switching surface 4221 and the second switching surface 4222 is increased, which results in a larger volume of the turntable 42, and the turntable 42 needs more rotation space and interferes with the stability of the fit.
