Technical data
Application
Housing material & colour: made from sheet steel, grey powder-coated bottom part made from electrogalvanised sheet steel, blue
The JPS is a universal pressure switch with 2 switching ranges, suitable for oil, water and air. It can also be used as a con- troller for domestic oil supply systems, pressure boosters, oil feed pumps etc.

Changeover switch (a) in normal range Switching range 1:
Pressure ranges (setting ranges) and differentials:
The starter knob works in such a way that the second switching range is bridged (if it is functio- ning as a safety margin). The red telltale remains lit up until the pressure required for the 1st switching range has been built up
can be set to between 1.0 and 4.0 kp/cm 2 Differential can be set to between 0.7 and 1.5 kp/cm 2 Switching range 2: can be set to between min. 0.3 and max.1.0
kp/cm 2 below the 1st range Differential fixed at 0.3 kp/cm²
(b) with increased pressure range : Switching range 1:
can be set to between 1.3 and 6.0 kp/cm 2 Differential can be set to between 0.7 and 1.5 kp/cm 2 Switching range 2: can be set to between min. 0.3 and max.1.0
kp/cm 2 below the 1st range Differential fixed at 1.3 kp/cm 2
