Features: When water flows through the preset channel, it displaces the magnet. As the magnet moves near the reed tube, the magnetic field activates the switch, causing conduction. When water stops flowing, the magnet returns to its original position via spring force, and the reed tube disconnects when no magnetic field is detected. Thread: G1/4-inch, startup flow: 300ml/min, response time: less than 1 second. Lightweight, compact design, stable performance, low water pressure start-up, easy installation, safe operation. Suitable for use in water dispensers, water purifiers, water vending machines, and similar applications. Constructed from high-quality materials for durability and long-term use.
