Claims

[Scope of utility model registration request]

A first switch for stopping rotation of the motor and changing the rotation speed, and a second switch that operates in conjunction with the first switch and simultaneously opens an open circuit only when the first switch creates an open circuit. The switching device comprises an A contact and a B contact that are selectively activated at different times in conjunction with a timer; is connected to a power source, and the lowest speed setting end for setting the motor to the lowest speed is connected to the power source via the second switch and the B contact, which operates for a predetermined time after the A contact. Device.
