The advantage of the water flows switch is that the water pressure is low. When the magnetic ring inside the piston is pushed to the position of the reed switch, the reed switch generates a signal. Reed switch water flows switch has stable working performance and is widely used in various equipment. And some piston water flows switches can adjust the reed switch operating point to change the flows signal, so it is the first choice for various types of equipment.
