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.
