      • Plunger and Ball Switches

        Plunger Switches
        Borrowing the same patented seal design as our J4-Ball Switches, our plungers can be customized with heat sinks and mounting specifications, and are IP68 rated. Learn More
        Ball Switches
        CPI Ball Switches see duty in critical military and industrial applications such as closure sensors for doors, hatches and valves. All stainless steel and double sealed for reliable actuation over a long life. Learn More

      • Momentary and Limit Switches

        Momentary Switches
        Our pendant style waterproof momentary contact switches are totally submersible and are designed to preserve seal integrity during activation over a long life. Learn More
        Limit Switches
        CPI Limit Switches are truly waterproof: not water resistant, or “splash proof”. Made of high grade stainless and designed for maximum electromechanical endurance. Learn More

      • Maintained Contact Switches and Waterproof Switch Panels

        Maintained Contact Switches
        These sealed, pendant style switches provide force adjustable tactile contact, ideal for use in power cycling applications in harsh duty environments. Learn More
        Waterproof Switch Panels
        With an operating temperature range of -50F to 221F our panel configuration has excellent resistance to both high and low temperatures, acids, alkalies, salt spray, sand, dust and fungus. Learn More

    Switches

      • Snap Stat (0F–300F)

        Snap Stat (0F–300F)
        Using a precisely engineered bimetal snap disc, we actuate a miniature microswitch through a double snap action. Multiple mounting options available. Learn More

      • Plug Stat (0F-650F)

        Plug Stat (0F-650F)
        Contact movement in the PlugStat is achieved by controlling the different expansion rates of 2 fused metals providing tight tolerances and a small differential. Learn More

      • Rod & Tube (0F – 1750F)

        Rod & Tube (0F – 1750F)
        Ideal for use in galley’s or furnace controls to sense or control combustion. Very high temperature sensing with very rapid response time. Learn More
