PRESSURE / VACUUM SWITCHES

Pressure / Vacuum Switches That are Built to Last

Pressure Controls was built on the durability and reliable performance of our line of Pressure / Vacuum Switches. Customers have come to rely on these components when they need high quality parts quickly with flawless operation under pressure.

PRESSURE SWITCHES EXPLAINED

Pressure / vacuum switches (also known as gauge pressure switches) are suitable for most applications that don't need to compensate for changes in barometric pressure. These types of pressure switches require venting to atmospheric pressure, usually in the form of a conduit or vent hole which equalizes the pressure between the sensing element and the outside environment.
