Cut-Off/Inertia Switch: Description

Some fuel injected models use an electrical interrupt switch in the fuel system. On Ford Motor Co. vehicles an inertia switch is used. The inertia switch disables the fuel delivery system when the vehicle is struck violently or when vehicle rollover takes place. It is mounted in various locations, depending on the vehicle model.
