1501L Microvac Safety Switch

The Beam 1501-L Safety Switch is vacuum operated and connected to your 12 volt solenoid. When the engine shuts down and loses vacuum for any reason, the safety switch closes the 12 volt signal to the 12 volt solenoid and shuts it off, making a positive lock off or safety shut off of the fuel system, even if the ignition switch is left on.
