Abstract
A commutator on-off detection mechanism with a self-checking function and a detection method thereof are provided, the commutator on-off detection mechanism includes an upper detection module and a lower detection module disposed directly below the upper detection module, the upper detection module is provided with upper resilient sheets, the lower detection module is provided with lower resilient sheets, and numbers of the upper resilient sheets and lower resilient sheets are equal. The upper detection module is configured to press a commutator downwards until the commutator is snapped into the lower detection module, thereby to make the commutator be in contact with the lower resilient sheets of the lower detection module, and the upper detection module is further configured to make the upper resilient sheets be in contact with the commutator. The device has high detection efficiency, does not require frequent replacement of accessories, and there will be no leakage or wrong detection.
