As shown in fig. 1 to 14, the intelligent auxiliary switch of the present application includes a contact switch unit 10, a rotating shaft connection unit 20, and an intelligent detection unit 30. The rotating shaft connecting part 20 comprises a connecting shaft 21, and the connecting shaft 21 is arranged in the contact switch part 10 in a penetrating way so as to control the contact switch part 10 to switch between a closed circuit state and an open circuit state through the rotation of the connecting shaft 21; the smart detection unit 30 detects the rotational position of the connection shaft 21 and transmits the actual state of the contact switch unit 10.

When the intelligent auxiliary switch with the structure is used, the connecting shaft 21 passes through the intelligent detection part 30, and the rotating state of the rotating shaft can be judged by detecting the rotating state of the connecting shaft 21 because the connecting shaft 21 and the rotating shaft of the electrical equipment rotate synchronously, so that the rotating state of the connecting shaft 21 is detected by the intelligent detection part 30, and a rotating state signal is sent to the external equipment, thereby realizing the real-time detection of the rotating shaft of the electrical equipment, and accurately judging the switching completion time of the switching state of the electrical equipment. The smart detection unit 30 can also transmit the actual state of the contact switch unit 10. Therefore, the intelligent auxiliary switch effectively solves the problem of the advance action of the contact switch.
