What is a Vacuum Switch?

A vacuum switch is an electronic or mechanical device that provides an electrical switching contact function at a defined vacuum gas pressure level. It’s used in many vacuum applications for pressure control purposes and safety interlock functionality.

Vacuum switches are an essential component for many monitoring and control applications in hydraulic, pneumatic and processing industries. Performing in critical processes, these switches sense a change in the vacuum and open or close an electrical circuit when the chosen setpoint is reached.

What are Vacuum Switches used for?

A Vacuum Pressure Switch operates by comparing the relative pressure between your process pressure and a vacuum.

The benefit of this technology is the ability to measure pressure below your local atmospheric pressure. To accomplish this, a vacuum switch has a sealed reference chamber, as well as a diaphragm and a Belleville spring to actuate when your pressure setpoints are reached.
