About Us
Waterproof 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.
    
    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.
    
    Rocker Switches
    
    These sealed, pendant style switches provide force adjustable tactile contact, ideal for use in power cycling applications in harsh duty environments.
    
    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 reliability.
    
    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.
    
    Switch Panels
    
    With an operating temperature range of -50F to 221F our panel configuration has excellent resistance to temperature, acids, alkalies, salt spray, sand, dust and fungus.
Thermal Switches
- - 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.
    
    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.
    
    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.
