Cable Float Switch

Cable Flow Switch with Counterweight (Gelzon Brand)

### *1. Product Overview*

The *Gelzon Cable Flow Switch* is a heavy-duty liquid level controller designed for automatic pump ON/OFF control in water tanks, borewells, sumps, sewage pits and industrial tanks. It uses a tilt-activated internal microswitch to detect rising or falling water levels and switch circuits accordingly.
