Features: When water flows in the preset flow channel, it pushes the magnet to displace it. When it moves to the corresponding reed switch, the reed switch conducts after sensing the magnetic field. When there is no water flow, the magnet returns to its position under the pressure of the spring, and the reed switch is disconnected after the corresponding reed switch cannot sense the magnetic field. Thread: G1/4 inch, starting flow: 300 ml/min, response time: less than 1s. Lightweight, reasonable size, stable performance, low water pressure start, easy to install, safe to use. Can be used perfectly for water coolers, water purifiers, water dispensers, etc. Made of high-quality material, which is sturdy and durable in use.
