    Pressure Switches for Oxygen

    Cleaned to ASTM G93 requirements and then bagged, these switches meet the strict cleaning standards required for oxygen service lines. Removing all contaminants extends the life of the switch and helps maintain a safe environment.
    When a set pressure is reached, these switches can turn equipment on and off, activate automated controls, or signal alarms. They have an internal setpoint adjustment with a sliding cover to prevent accidental setting changes. 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 rated, they seal out dust and water from washdowns and the weather. These switches also meet UL 508, are CE marked, and are UL and C-UL recognized components, so they meet American, Canadian, and European safety standards.
