Abstract
A centrifugal actuator assembly for an electric motor or the like is provided having a pair of opposed movable members rotatable with the rotor shaft of the motor and responsive to centrifugal force upon rotation of the rotor shaft for movement between a run and a start position. The movable members are biased inwardly toward their start position by means of compression coil springs interconnected between the movable members by means of a linkage designed to improve operating life of the centrifugal actuator.
