ABSTRACT:
A sensor for responding to the rate of change of changing rotational speed of a rotating member such as a vehicle wheel and including a flyweight coupleable for rotation in response to wheel rotation and selectively decoupleable in response to the exertion on the flyweight of an inertia torque having a magnitude greater than a threshold magnitude due to a change in rotational speed of the member. In accordance with the present invention, control means for exerting on the flyweight torques resisting decoupled rotation of the flyweight takes the form of a restraining mechanism, while signalling of any occurrence of an excessive rate of change of rotational speed of the member is accomplished through a magnetically actuable electrical switch.
