• Stable performance: The induction chamber, magnetic control chamber, and electronic components are designed separately to prevent switch failures caused by iron matter in the pipe being magnetically adsorbed. • Excellent material: High-temperature resistant materials allow the product to be used for both hot water (up to 70 ℃) and cold water. • Low water pressure start: The reset spring is made of high-quality stainless steel; It can start the pump when the water pressure is > 0.03 KG. • Apply to: This flow switch is widely used for low-pressure area families, especially important for ignition by low water pressure of the water heater, automatic water cycle of the solar water heater. • Safe adjustable: Electronic components as a control device will not cause sparks during work, which is quite safe. The sensitivity of this flow switch is adjustable. • Product measurements: 4 cm wide, 6.3 cm high, 6 cm long.
