The installation position can change the switching pressure with up to 0. VR – mbar N. HFSV – butterfly valve N. MV – 1 bar, one-stage N. The pressure switch operates without auxiliary power. The switching mechanism responds if there is an overpressure which switches on, off or over to an electric circuit if the set reference value tw exceeded or undershot. Single-acting pressure switch in the overpressure range.

The test nipple is integrated in metal housings as standard. The switching mechanism responds to vacuum which switches an electric circuit on, off or over when dunhs set value is exceeded or undershot.
