Switching mechanism and motor

The utility model provides a switching mechanism and a motor. The switching mechanism comprises a conductive mounting frame and a conductive brush, the conductive mounting frame is provided with a containing cavity used for containing the conductive brush, and the conductive mounting frame is arranged on the end cover of the motor and located in a gap between the end cover of the motor and the dynamic balance plate. The conductive brush elastically abuts against the rotating shaft of the motor, so that a certain radial telescopic movement allowance exists between the conductive brush and the rotating shaft, and meanwhile close contact is improved. The conductive mounting rack is connected to the end cover to lead out the current of the rotating shaft to the end cover. According to the switching mechanism, the conductive brush is installed between the end cover and the dynamic balance plate of the motor through the conductive installation frame without installation of a lead, the conductive brush leads out cur
