The Nason CJ-2C3-40G/HM Low Pressure Switch uses a snap-action to activated the electrical contacts through an elastomer diaphragm, offering a precise and repeatable design. The snap-action design will maintain its state with contacts either open or closed, until a precise set point is reached when it will snap over center to a new state. It will remain in that state until a distinct change towards its original setting is sensed, at which time it will snap back to its original state. The design’s snap-action feature prevents contact intermittency near its switch point, which is common in creeper designs. As system pressures fluctuate, the CJ-2C3-40G/HM's inherent differential prevents searching. Nason uses only the highest quality snap-action switches. The Nason CJ-2C3-40G/HM is UL, CSA, and military approved. Our elastomer diaphragm, which moves a precise .040 of an inch, ensures accurate, instantaneous contact under all operating conditions. While nitrile is preferred for general use, we can also provide ethylene propylene, fluorocarbon, fluorosilicone, and neoprene, depending on your need. Nason tests 100% of its switches for accuracy and reliability Under most operating conditions.  Nason switches have an operational life of over one million cycles. Smart design, quality components, and careful assembly make a switch that easily outlasts the competition.
