Buoyancy based design with simple, robust construction Principle and structure: The float switch operates on buoyancy, offering a simple and reliable mechanism for liquid level control. Direct connection option: Can be used directly for motors under 750W; for motors 750W or higher, use an AC contactor. Sealing and materials: Sealed with polypropylene for good protection against moisture and contaminants. Environment resistance: IP68 rated, suitable for submerged or wet environments. Environment and safety: Easy automatic adjustment, straightforward installation, safe and reliable, and green and environmentally friendly. Key specifications Rated voltage: AC 380V Maximum current: 16A (models available with 10A and 5A variants) Maximum operating temperature: 90 C Protection level: IP68 Construction: Float switch designed to control liquid level in a barrel, tank or well Material: Polypropylene sealing What it does and why you need it Function: Adjusts and maintains liquid level by turning pumps on or off to prevent overfilling or running dry. Compatibility: Suitable for use with barrels, tanks, wells; can be installed on submersible pumps to control and protect the motor when liquid level is low. Ease of use: Easy automatic adjustment, simple installation, and reliable operation. Durability: Sealed polypropylene housing provides strong resistance to moisture and dust in harsh environments. 23 practical use scenarios Scenario 1: In a storage barrel or small tank, the float switch automatically starts and stops the pump to maintain a desired liquid level without manual monitoring. Scenario 2: In a submersible pump setup, the switch protects the motor by stopping the pump when the liquid level is low, preventing dry running. Scenario 3: In an industrial tank or sump, the float switch provides automatic level control to maintain process consistency and reduce operator intervention. Notes on usage and installation For motors under 750W, connect directly to the pump. For higher power applications, use with an AC contactor as appropriate. Ensure the operating environment remains within the IP68 rated conditions and temperature limit (up to 90 C) for long service life. Select the appropriate current variant (10A or 5A) per your pump and circuit requirements.
