The RSF64EXS & RSF64EXT Series is a vertical float switch, with either normally open or normally closed (when the float is down) switching action, permanently coupled to a 300mm PVC tube. This provides a float switch, whose overall depth can be varied between 150mm and 450mm, by adjusting its position in a sliding clamp. Further 306mm PVC extension tubes may be added, up to a maximum of three, to provide insertion depths up to 1350mm.
