400 series switch
The 400 series pressure, differential pressure, and temperature switches are a versatile series of switches, particularly suitable for situations where multiple output and control points are required. Two point and three point settings provide multi-point output, which can be used for alarm and shutdown, early warning and alarm, high/low limit and liquid level control functions.
