Diaphragm vacuum switch

The Euroswitch 38/35/37 series combines advanced pressure and vacuum switches in one versatile product line. Specially designed for demanding industrial applications. Whether monitoring light negative pressure, precision vacuum or working pressure up to 10 bar, this series offers reliable switching performance with a long service life. The pressure switch is suitable for both fixed installations and mobile systems.

Thanks to its robust housing, such as brass or AISI 316L stainless steel, and a wide range of diaphragm options (NBR, FKM, EPDM, CR, HNBR), the series can be easily adapted to your specific process conditions. With protection ratings from IP00 to IP65 and optional UL508 certification, these switches are suitable for a wide range of industries, from machine building and pneumatics to hydraulic applications.
