Model PSM02 screw-in pressure switches in a diaphragm or piston design open or close a circuit, depending on whether the pressure is falling or rising. With one adjustment screw, respectively, the required switch point and the switch hysteresis can also be easily and conveniently set on-site.
Optionally, WIKA offers its customers the factory setting of the switch point.

Model PSM02 mechanical pressure switches are employed wherever compressed air, neutral and self-lubricating fluids or neutral gases are used and a precisely set switch hysteresis is needed.

The high reproducibility of the switch point of ±2 % and the adjustable switch hysteresis make the model PSM02 pressure switches interesting for all customers who place a value on precision as well as an attractive price.
