A device for switching in and out a start winding of a single phase AC motor using an energizer winding to generate voltage which can be used to power a simple timing switch circuit. The AC voltage is rectified and converted to DC voltage. The DC voltage is then used to drive a normally closed solid state switch to an open state which in turn inactivates a triac connected to the start winding in the motor. The 'on time' of the start winding is controlled by a RC circuit that ramps the voltage to the gate of a FET that drives current through the normally closed solid state switch.
