ABSTRACT:
A centrifugal actuator for an electric motor starting switch which is rotatable with the rotor shaft of the motor and which is movable axially with respect to the rotor shaft. A spring biases the centrifugal actuator into engagement with a fixed stop carried by the housing of the electric motor so that the position of the centrifugal actuator with respect to the motor starting switch remains fixed and is not affected by axial movement of the rotor shaft within the electric motor housing.
