Working principle:
The liquid level sensor is mainly composed of magnetic reed switch and floating ball, there is magnetic material built-in the floating ball, and one or more reed switches arranged in a closed non-magnetic metal or plastic tube, then put the tube through one or more floating ball with magnetic material, and keep floating ball and magnetic reed switch in the related position with fixed double ring. As the liquid rises or falls, the floating ball makes use of the contact point close to the beginning of the magnetic spring inside the ball to produce the action of opening and closing for liquid level control or indication. (When the float is close to the reed switch, it is conducting; Switch off when leaving.)

Tip:
The max switching current of the contact is 0.5A. Generally, it should be used together with small relay. Excessive current will burn the contact. Cannot directly control AC contactors, solenoid valves, alarms, pumps, and various lights.
