Abstract
This disclosure relates to a circuit for controlling energization of a start winding of a single-phase motor connectable by power lines to an AC power supply. The circuit includes at least two triacs connected in back-to-back series relation and connected in series with the start winding. The circuit further comprises a reed switch including reed contacts and a reed coil. The gates of the two triacs are connected across the reed contacts, and the reed coil is connected in one of the power lines and receives the line current during energization of the motor.
