Description
The EFQS-4 Series Cable Float Switch is designed to automatically control liquid levels in tanks, wells, and reservoirs. It features a double-shell float design to ensure stable buoyancy and reliable switching.
The cable uses 0.85 mm² thickened conductors, significantly stronger than standard 0.4 mm² cables, allowing higher load capacity and improved electrical safety.
The switch is easy to install, maintenance-free, and resistant to sewage and contaminated liquids. By connecting multiple float switches in series, users can effectively protect pumps from dry running and achieve multi-point level control.

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.
