  • Patent number: 5744883
    Abstract: A switch lever for use with a centrifugal starting switch of an electric motor. The starting switch has at least one switch contact which is moveable, in response to axial movement of a centrifugal actuator, between a start position in which a starting winding of the motor is energized and a run position in which the starting winding is de-energized. The switch lever of the present invention operatively connects the switch contact with the centrifugal actuator for movement in response thereto. The switch lever has a cam follower at one end which is engageable with an annular actuator collar of the centrifugal actuator. The cam follower includes a contoured rear cam face which prevents the cam follower from becoming "stuck" behind a flat rear surface of the actuator collar during assembly or operation of the motor.
