A fuel safety switch for the fuel system of a motor is designed to be placed in the fuel delivery system and includes a bellows responsive to the pressure of the fuel within the fuel system for expansion outwardly, coil springs disposed on both sides of the bellows to provide a snap action return of the bellows to a collapsed condition after a reduction in fuel pressure, a first set of contacts activating an over fuel indicator when the bellows is expanded beyond a predetermined limit, and a second set of contacts activating the motor brake retarders, if turned on, when the bellows collapses to the unexpanded state.
