The C25 inline flow switches have a compact design, with a magnetically-actuated piston that switches in response to flow. They are ideal for many types of pressure boosting and control applications in both hot and cold liquids up to 90ºC. The C25 flow switches can be supplied with reed switch contacts for relay or PLC control or with a built in 40Amp solid state switch for the direct control of single phase motors up to 3kW 4HP.

For safety shower applications we recommend using our C25-B model with the dry contact reed switch.
