It is called an inertia switch because it works on inertia, i.e. > activated by a sudden shock. It was my understanding that the plunger is pushed up by a ball laying in a cup; when the car turns over or if a shock is applied the ball comes up out of the cup, thus pushing up the plunger. The Inertiaswitch shuts off the fuelpump AND unlocks both doors if they were locked... I remember seeing an illustration of the inner workings of the InertiaSwitch, but I can't find this picture anymore (it's late...) Maybe someone else knows where to find this illustration?
