DIETZ Pressure, Vacuum, and Differential Switches

Pressure, Vacuum, and Differential Switches for Extreme Environments

Highly sensitive and precise, yet built for harsh industrial use.

Since 1947, the Henry G. Dietz Company has designed and built heavy duty low pressure switches, vacuum switches, and differential switches for construction, earth moving, marine, rail transportation, clean rooms, military, chemical and sewage plants, and many other demanding applications.

Now a part of the World Magnetics family of pressure, vacuum, and differential switches, Dietz models continue to deliver the long-lasting accuracy, repeatability, and reliability that has set the industry standard for over 60 years. Whether you require air pressure and air flow detection, or protection of air-cooled electronic equipment, you can count on Dietz for rugged, yet precise performance.
