APPLICATIONS Pressure switches for booster sets. The switch automatically ensures the start and stop functions of the electric pump according to the set pressure values PRESSURE SWITCHES WITH ADJUSTABLE DIFFERENTIAL When setting the pressure switch, adjust the switching point on starting (PH) first and then the switching point on cut-off (PB). Switching point on starting The switching point on starting (PH) is set by adjusting screw-nut 1. Switching point on cut-off The switching point on cut-off (PB) is set by adjusting screw-nut 2.
