This water flow switch uses a water flow electromagnetic control device and on-off control sensing elements to enable automatic pump operation. The induction chamber, magnetic control chamber, and electronic components are independently designed to prevent switch failure due to magnetic attraction of iron particles in the pipeline. Constructed with high-temperature resistant materials, this product is suitable for both hot water (up to 70°C) and cold water applications. It activates the pump at a water pressure as low as 0.03 kg/cm². The electronic control components operate without generating sparks, ensuring safe performance. Made from high-quality copper, the switch offers durability and high structural strength. The unit measures approximately 7 cm x 7 cm. This water flow switch is commonly used in residential low-pressure water systems, particularly for enabling ignition in water heaters under low water pressure conditions and supporting automatic water circulation in solar water heating systems.
