We are specialists in position sensing, in other words feed back signal from a linear or rotary sensor. With our experience we will guide you to the best solution, no matter if you need some standard components from our stock or larger quantities of a customized sensor.

Pressure switch P/PS

Trafag‘s mechanical pressure switches offer high vibration resistance and switchpoint accuracy in combination with an extraordinary rugged design for years of maintenance-free operation in rough conditions. Different sensors based on bellow, membrane and piston principle cover a wide range of pressure ranges, media and load cycle profiles.

P/PS pressure switches are used for low pressure ranges where high accuracy is needed. The PS pressure switch is like the P-version but without the see-throug lid.
