When they started using fuel injection in cars, they found that if a car was in an accident, that as long as the key was on, the fuel would continue pumping. The last thing you would want would be for gas to be spraying all over a car with wires sparking, and hot engine parts, and even a fire. So, they came up with an inertia switch. When it senses a strong enough bump, it shuts off the fuel pump. I'm not sure what the different car companies put them. Some had reset switches. I think some were even in the glove compartment, but I know Ford and Mercury had them in the trunk where you could reset them fairly easy. My brother had a Mercury Sable that blew a tire once. That was enough to trip the inertia switch and shut down the car.
