Re: [DML] Inertia Switch Impact force

Jim,

The purpose of the inertia switch is to cut power to the fuel pump in the
event that the vehicle becomes inverted (overturned) while the engine is
running, in order to prevent a fuel ignition. The mechanism is a weighted
plunger switch, where the open circuit (off) mode is in the UP position. If
I am incorrect on this point, someone feel free to correct me.
