Welcome
We have 10 years of experience in the production of flow switches, insisting on professionalism, focus, single-mindedness, and customer-centricity are our continuous progress.
How the flow switch works
SK-DN25-DB, flow switch
The inner baffle is pushed up by the water flow, and the reed switch in the outer sensing rod senses the magnetic trigger signal (ON) above the baffle, and automatically resets the disconnection signal (OFF) when there is no water flow.
