Water Purifier Switch

The water purifier pressure switch, including high and low-pressure switches, is a common electrical component in water purifiers. It is mainly used to monitor pressure changes in the water circuit and control the booster pump or cut off the circuit based on actual conditions, ensuring the safety and stable operation of the system. The high-pressure switch is typically directly related to the pressure state of the water storage tank, while the low-pressure switch is often used in cases of insufficient water intake, interrupted water source, or abnormal inlet water pressure.
