The RSF166 Series float switch is designed to offer a number of switching options to meet a variety of system requirements. These are manufactured in PPS (Polyphenylene Sulphide), which is compatible with a wide range of liquids, and are mounted externally via a compression seal and a 22mm diameter hole in the tank.

The single float types are generally used in systems with PLC control of processes. The dual float versions can be used for controlling the filling or emptying of tanks via electromechanical relays.
