The 400 Series is a versatile family of pressure, differential pressure and temperature switches for applications which require single or multiple switching capabilities. Dual or triple switch versions provide multi-output in applications such as alarm and shutdown, pre-alarm and alarm, high\/low limit or level staging functions. They are available in both hex screw adjustment and dial set point adjustment versions, and have a wide variety of available options.","Triple switch J403’s may be used for liquid level control. In this application, three pressure settings correspond to \"pumping out\"elevations in a sump pump. The 400 Series continues to be widely used throughout the process industries, from industrial gas production, energy generation, and pulp and paper, to applications involving pumps, turbines, compressors and heavy equipment, where threshold protection and control of functions is required.
