Switch

  This switch adopts to the temperature controlling Principle, it’s design of special switches for Heating system hot water circulation pump. thus, saving much cost on purchase other temperature controlling device. it can connect with the pump directly as a discreteness of water pump, Enable ordinary hot water circulating upgrade to a automatic temperature controlled circulating pump. there have four stages on the pump. viz. the High stage 60oC, middling 50oC, low 40oC and uninterrupted. When the sensors detect the temperature higher than the set value, the pump will working automatic, when the temperature lower the set value, the pump will stop working. simplenss and convenience. The Temperature, stage and control mode are can adjusted against the different requirements.This switch??s sensor is high precision NTC, Have strong magnetism, Sensors and switches can be separated, also can Individual fit out.The Switch Standby prower < 0.1W, The Max Tolerant Current 220V/5A.

  The switch adopts electronics theory, controlled by water current. It is widely used in mini boosting pumps, solar water-heaters and industrial equipments. When water is on, it will start automatically. Otherwise, it will stop automatically and can adjust sensitively according to the differences pressures. This switch has few troubles and long life. It can be used 20 thousand times without any stoppage. Different types are for different size motors.
