Accessories
What is the difference between single ball and double ball models?
Single Ball: Uses one float for basic water level control, suitable for simpler systems and smaller tanks. Double Ball: Uses two floats for more precise water level monitoring, often in systems requiring dual-level detection. It also uses four 30CMPVC wires for added durability and flexibility.
What materials are used in these float switches?
Both models are made of 316 stainless steel (SU304 for standard series) for the float and body, ensuring corrosion resistance and long service life. Single Ball: uses two high-temperature braided wires for durability and heat resistance. Double Ball: uses four PVC wires for flexibility, wear resistance, and long-term use.
Can they be used in high-temperature applications?
Yes, single ball switches have two high-temperature braided wires rated for 120°C, while double ball switches use four 30CMPVC wires rated for 80°C. The switches themselves operate safely in environments from -30°C to +120°C.
Are these switches suitable for corrosive liquids or oils?
Yes, the stainless steel construction, PVC or silicone-insulated wires, and thickened sealing gaskets make both models resistant to acids, alkalis, oils, and various chemical media.
How does the magnetic reed switch work?
The magnetic reed switch is controlled by a ring magnet inside the float. It provides accurate on/off control without requiring an external power source. OKI reed switches are used for higher reliability and longer operational life.
How easy is installation?
Both single and double ball models are straight-rod designs, allowing vertical or top mounting inside tanks or containers. The compact design makes them suitable for narrow or space-limited tanks and devices.
What types of applications are suitable?
Water purifiers, drinking machines, and small household appliances Water heaters, solar water systems, and coffee machines Air conditioners, humidifiers, and small refrigerators Automotive liquid systems, industrial liquid control, and agricultural irrigation equipment Anti-dry protection systems for heating equipment
How long is the service life?
The stainless steel construction, reinforced wires, thickened sealing gaskets, and magnetic reed switch provide long-lasting, stable performance.

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
