Abstract
An electrical circuit for controlling start windings in induction motors of various sizes or horsepowers providing a broad range of application. The circuit for controlling start winding switching measures the current through both the start and run windings of the motor allowing the use of a single solid state device in the circuit. This combined current develops a voltage across a resistor which is used to gate on the solid state device when the voltage exceeds a threshold level. By using the solid state device in combination with the special resistor, a motor start switch is formed which can be used to start a wide range of dual voltage motors.
