Abstract
A combination high pressure switch-low pressure switch and high pressure relief valve control device is disclosed having series connected high and low pressure switches which are held closed to complete a control circuit in a normal pressure operating range and are respectively responsive to pressures above and below this range to open the control circuit. A high pressure relief valve is also integrated into the control device and operates to provide high pressure relief to atmosphere at pressures substantially above the high pressure switch actuating pressure.
