Up to 50 Mtr Cable Float Switch

cable type float switch is a simple, reliable device used to automatically control liquid levels (usually water) in tanks, wells, or sumps.

A cable float switch consists of:

A floating body (usually plastic)

A cable with a weight

An internal switch mechanism (like a ball or mercury-free contact)

⚙️ How it works

The float sits on the surface of the liquid.

As the water level rises or falls, the float tilts.

This tilt activates an internal switch, which:

Turns ON a pump (when water is high), or

Turns OFF a pump (when water is low)

🔁 Types of operation

Normally Open (NO) – closes circuit when level rises

Normally Closed (NC) – opens circuit when level rises

Can be wired for:

Filling control (overhead tanks)

Emptying control (sump/drainage)

 Common applications

Water tanks (overhead & underground)

Borewells

Sewage and drainage systems

Industrial liquid tanks
