The working principle of the float level switch is direct and simple, usually set a point or a few points of Reed Switch in a sealed non-magnetic metal or engineering plastic tube.And then fix the float ball with magnetic system builtin in the position of reed switch which in the tube body, letting the float fluctuate within a certain range. Using of the magnetic system of the float ball, activate the reed switch to open or close through the tubebody. In the result of producing switching action and control the level.





Float level switches are widely used in electronic, electrical, chemical, water treatment, drainage and other industry of level control and alarm.
