Reference description: The float level switch is a simple and easy-to-use liquid level control device. It does not require power supply and no complicated circuits. It has the advantages of smaller volume and longer working life than ordinary mechanical switches. As long as the material is selected correctly in the styling, and it can be used with any nature liquid or pressure, temperature, it is widely used in shipbuilding industry, generator equipment, petrochemical industry, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. application.
Working principle: The liquid level sensor is mainly composed of a magnetic reed switch and a float. There are magnetic materials in the float. One or more reed switches are set in a closed non-magnetic metal tube or plastic tube, and then the catheter is passed through a Or multiple floats with magnetic material, and the fixed double ring is used to control the float and the reed switch at the relevant positions. The float rises or falls with the liquid, and the contact inside the ball close to the beginning of the reed is used to open and close. The action of the liquid level control or instructions (when the float is close to the reed switch is turned on; when left, the switch is turned off).

A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or other device.
Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating etc.
Working theory:
One or more reed tubes are mounted in a closed, non-permeable tube.
Then the tube is passed through one or more of the hollow and internally floating magnets.
The rise or fall of the liquid level causes the floating ball to move together, thereby causing the reed switch in the non-permeable tube to be actuated to open or close and output a switching signal.
Note:
Float used in conjunction with the relay can not be directly used with the power supply.
