。 Two non-contact switches connected to the main circuit open and close the power supplied to the motor, and a control signal given via a soft start circuit based on the motor setting signal and a synchronization signal synchronized with the power supply voltage. In a power control device for a non-contact switch, the power control device includes a phase control device that controls the opening/closing operation of the non-contact switch at a timing corresponding to a firing angle. A reversible operation switching circuit is provided that sends an operation control signal to each of the two non-contact switches to control switching between forward and reverse rotation, and also starts a soft start circuit when starting the motor and when reversing forward and reverse rotation. A power control device for a non-contact switch, characterized by:
