Claims

[Scope of utility model registration request]

By turning on the power switch, voltage is applied to the input side of the motor starting relay connected to the motor, and then by turning the feed switch on or off, the motor starting relay is controlled via the control relay, and the motor starts. A first relay that is connected between the motor starting relay and the control relay and controls a motor drive signal voltage input to the control relay, and a first relay that drives the first relay. Turn the feed switch south 1. A motor start/stop circuit comprising: a second relay consisting of a second relay;
