    Prevent changes to the set pressure that activates equipment—these switches come ready to use at your preferred setpoint. Often used to turn equipment on and off when a set pressure is reached, they can also be used to activate automated controls or signal alarms. They’re single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed).

    NEMA 4 and 13 rated, they seal out dirt, oil, and water from washdowns. These switches are also UL and C-UL recognized components and are CE marked, so they meet American, Canadian, and European safety standards.
