Title: Central Air Conditioner Liquid Level Sensor Float Switch For Daikin Haier Gree

Working principle of ceiling air conditioner float switch and water pump

Usually one or more reed switches (reed switches) are set in a sealed non-magnetic metal or plastic tube as needed, and then a hollow float with a ring magnet inside is fixed to the reed switch (reed switch) in the rod diameter In the relevant position, the float is made to float up and down within a certain range, and the magnet in the float is used to attract the closing of the reed switch to produce a switching action, so that the float switch achieves the function of controlling the sensing and detecting water level. Normally open and normally closed are the states when no liquid is injected.
