The pressure switch MDR-53 is suitable for use in oil, water and air, and is fitted with 1 change-over contact, plus die-cast aluminium pressure connector and CR diaphragm. The pressure switch is fitted as standard with the possibility for pressure difference adjustment. Pressure adjustment is possible without tools. A handwheel permits switching point and hysteresis to be adjusted, whereby the cut-out pressure is adjusted with the handwheel in the upper position (the spindle also turns). By selecting a pair of values for cut-in and cut-out pressures, an intersection point is determined in the diagram. If the point lies within the shaded area, this pair of values can be adjusted (without tools) on the pressure switch. If the point lies outside the shaded area, this pair of values cannot be adjusted on the pressure switch.
