Usage Tips: This water flow switch uses a water flow electromagnetic control device and on-off control sensing elements to achieve automatic pump control. The induction chamber, magnetic control chamber, and electronic components are separately designed to prevent switch failure caused by magnetic adsorption of iron particles in the pipeline. Constructed with high temperature resistant materials, the 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 components used as control devices do not generate sparks during operation, ensuring safe performance. Made of high-quality copper, this switch offers durability and high strength. The dimensions are 7 cm x 7 cm. This water flow switch is widely used in residential low-pressure water systems, particularly for low water pressure ignition in water heaters and automatic water circulation in solar water heating systems.
