ABSTRACT:
An inertia-actuated circuit breaker for protecting an electrical circuit of a motor vehicle in the event of collision or overturning of the vehicle, the circuit breaker including a piston with a conductive element. The piston is axially slidable inside a case between a rest position and a circuit-breaking position. In the rest position, the conductive element bears against two contact studs of the electrical circuit. A ball is resiliently maintained in a rest position between a seat of the piston and a seat of the case by a spring. The studs of the electrical circuit are mounted to be axially slidable relative to the case to permit the piston to slide axially in opposition to the resiliently yieldable force exerted by the spring and are resiliently yieldably biased against the conductive element.
