Pressure switches DV7.2
With two adjustable change-over switch
Easy and precise adjustable hydromechanical pressure switch based on the piston-spring principle. When the oil pressure rises to the set value, the built-in microswitch is actuated - when the pressure drops, the switch is released. 7 pressure ranges for optimum adaptation to any operating pressure.
