Important Notice
The internal reed switch uses small contacts and is designed solely for signal output. It cannot directly drive electrical loads. To control devices such as contactors, motors, solenoid valves, water pumps, or alarms, an intermediate relay must be used. Direct connection to such devices may damage the water flow switch.

Please confirm the correct connection type before placing your order. For any questions or assistance, feel free to contact us.
