Made of high-temperature resistant material, this water flow switch can be used with hot water up to 70°C. The pump can start at a water pressure as low as 0.03 kg. Featuring electronic components as the control device, it operates safely without generating sparks. This switch uses a water flow electromagnetic control system and on-off sensing elements for automatic pump control. The induction chamber, magnetic control chamber, and electronic components are separately designed to prevent failure due to magnetic attraction of iron particles in the pipeline. Constructed with high-quality plastic and metal materials, this flow switch is durable and reliable. It measures approximately 7 cm in length and 5.2 cm in height. Ideal for low-pressure household applications, it is especially suitable for low water pressure ignition in water heaters and automatic water circulation in solar water heating systems.
