Operation

A steel ball (1) is fitted in a conic seat (2). It is normally held in position by a magnet.

With certain specific acceleration loads, the ball is freed from the magnetic attraction and gradually moves upwards out of its conical seat according to the angle of the cone.

A fast release mechanism (3) is located over the ball. This usually creates a normally closed (NC) electric circuit.

When the mechanism is hit by the ball it shifts the NC circuit to normally open (NO) thus cutting the fuel pump earth circuit.

The inertia switch can be restored by pressing the button covered by a flexible guard (4).

Note: If even after a slight crash you can smell fuel or if you notice leakages from the fuel feed system to not reset the inertia switch. Seek the cause of the problem and solve it before resetting the switch to avoid the risk of fire.
