Danfoss RT Pressure Switch


RT switches are used in general industrial, heating and marine sectors.

The RT single pressure switches series consist of a variety of controls including neutral zone pressure switches and safety pressure switches for steam boiler plants.

The Danfoss RT pressure switch programme covers working ranges from -1bar up to 30bar. The switches feature high accuracy, repeatability and stability over time, making them highly reliable. Outstanding vibration stability ensures for flawless operation even in heavy-duty applications.

All contacts are “snap-action” types, maintaining the contact force until the moment of contact break. Units with gold-plated contacts are ideal for low electrical loads while the silver-cadmium contacts are developed for high loads.

RT switches have been in service for more than 70 years.
