Abstract

A centrifugal actuator for activating a stationary switch in a single phase induction motor which has a hub with a central opening inside a central body portion for assembly and securement on the shaft of a motor for rotation thereby. The hub has a flat outer member for contacting the switch to actuate starting windings of the motor when the motor is in a rest condition and is removed from the switch under centrifugal action by weights located inside the actuator to cut out the starting windings when the motor is in a run condition.
