ABSTRACT:
A tilt actuated circuit breaker that discontinues the flow of electrical energy from a battery through the ignition system of a motor vehicle when the vehicle is involved in an accident. Longitudinal and transverse undulated tubes, each containing a heavy metal ball, define respective paths which permit either one of said balls to contact one of three triggers in the event of an accident to open a switch to break the electric circuit. All three of the triggers are interconnected with a trip arm in a manner whereby actuation of any one trigger by a ball will operate the trip arm to open a latch, permitting movement of a first contact arm of a switch in the circuit out of engagement with a second contact arm. A switch reset tool is built into the device which may be manipulated to re-engage the contact arms to re-establish the circuit.
