Low Pressure Ignition or Electric Fuel Pump Shutoff Switch

For example, wire this switch between your ignition switch and the coil, to prevent engine damage when you have a system failure.  The switch shuts off the ignition or electric fuel pump when oil pressure drops below 12 psi.  The switch must be used in conjunction with a momentary bypass toggle switch to allow the engine to start.  Hold the switch down while engaging the starter, when the engine is running, release the toggle.
