Abstract
A two position switch of an electric motor has an actuator that is biased by a resilient terminal arm into sliding engagement with an annular collar of a centrifugal actuator. The centrifugal actuator collar controls movement of the switch actuator which closes and opens electrical contacts to energize start and run winding circuits of the motor. The resilient terminal arm that closes the star circuit is slotted to reduce its biasing force exerted on the actuator of the switch.
