Cut-Off/Inertia Switch: Operation

In the event of a collision or vehicle roll-over, electrical contacts within the inertia switch shut off fuel supply to the electric fuel pump. Fuel supply will be interrupted even if the engine is still running. Switch contacts are normally closed, but open upon impact or roll-over. A reset button is located on the switch assembly. If the electrical circuit trips, it is not possible to re-start the vehicle unless the switch is reset by depressing the re-set button. Anytime the switch opens, the fuel system should be inspected for damage prior to resetting.
