Pressure and Vacuum Switches

Because these switches work with both positive and negative (vacuum) pressures, you can use them in applications that span both. For example, these switches can turn on a light when they reach the setpoint to indicate which pressure is flowing. They’re also often used to trigger automated controls and activate alarms. These switches are single pole, double throw (SPDT) and can either turn one circuit from off to on or from on to off.

NEMA 4X and IP66 rated, they’re dust tight and protected from washdowns and corrosion. All are UL and C-UL listed, CSA and CSA-US certified, and CE marked, so they meet U.S., Canadian, and European safety standards.
