MAGNETIC CONTROL: This water switch uses water magnetic control device and on-off control sensing elements, so as to switch on or off pump. HIGH TEMPERATURE RESISTANT: High temperature resistant material is used to make sure that the switch can be used in hot and cold water. The maximum temperature can reach 70C°. STABLE PERFORMANCE: Induction chamber, magnetic control chamber and electronic components are designed separately in order to avoid switch failure caused by iron matter in pipeline is magnetic adsorbed. LOW WATER PRESSURE STARTUP: Reset spring is made of high quality stainless steel; it can start up pump when water pressure is >0.03KG. SAFETY ENSURED: The electronic components as control device will not cause spark during work which is quite safe., Weight: 0.3086471668 pounds, Manufacturer: Hilitand
