Abstract
A solenoid-operated valve is disposed in the fuel line of an automobile to interrupt the fuel flow to the carburetor when the solenoid is deenergized. The solenoid operated valve is maintained in its fuel-open position only when both the automobile ignition switch is closed and a supplementary concealed switch is closed. The circuitry for operating the valve may include either a relay or an electronic device. An indicator light is illuminated during the fuel-closed position of the solenoid operated valve as a reminder that both switches must be operated to permit vehicle movement.
