F61KB Water Flow Switch

The F61KB-11C Liquid Flow Switches are single-Pole, Double-Throw (SPDT) flow switches that are used in liquid lines carrying water, ethylene glycol, or other liquids not classified as hazardous. They can be wired to energize one device and de-energize another device powered from the same source when liquid flow either exceeds or drops below the set flow either exceeds or drops below the set flow rate.
