ABSTRACT:
This disclosure relates to a centrifugal mechanism and switch construction particularly for use in an electric motor. The mechanism includes a support part that is secured to and rotates with the motor shaft, and a weight that is carried by the support part. The weight has its center of gravity to one side of the motor axis, and the weight is pivotally attached to the support part. Centrifugal force tends to swing the weight in one direction and springs connected between the support part and the weight tend to counter the centrifugal force. A lightweight disc is pivotally connected to the moving end of the weight, the disc being located to activate the switch. The weight and a hinge member form a parallel arm connection between the disc and the support part.
