Piston pressure switches 28V – 280V

Euroswitch piston pressure switches (models 30/30V, 40/40V) are an ideal solution. These compact, mechanical pressure switches are used worldwide in hydraulic systems, compressors, presses, industrial cooling technology, and mobile vehicles.

Thanks to their configurable operating range and versatile connection options, these pressure switches can be easily adapted to specific installations. Depending on the model, they are suitable for low or medium voltage switching up to 48 V (model 40/40V) or 250 V (model 30/30V) with a maximum operating pressure of up to 450 bar.

The mechanical operation based on piston technology ensures greater durability and reliability, even with intensive use. Thanks to the integrated adjustment screw, users can fine-tune the desired switching pressure while maintaining high tolerances and stability during temperature changes.
