Float Switch Sensor For Water Level Controller With 2 Meter Wire
Overview
A Float Switch Sensor (with 2 meter wire) is a simple and reliable device used to automatically control water levels in tanks, sumps, and reservoirs.
It works by floating on the water surface and switching ON/OFF based on the level.
Working Principle
The sensor contains a floating body + internal micro switch
When water level rises float tilts upward switch changes state
When water level drops float falls switch resets
This action can:
Turn pump ON (low level)
Turn pump OFF (tank full)
Operates mechanically without direct contact electricity in water

Overhead water tanks
Underground tanks / sumps
ains
Automatic motor ON/OFF systems
Working Example
Water Level | Float Position | Action |
Low | Down | Pump ON |
High | Up | Pump OFF |
Prevents:
Tank overflow
Dry running of motor
Important Notes
Install with correct cable length and counterweight
Avoid direct heavy current use relay for safety
Keep away from turbulence (waves can cause flickering)
Ensure proper waterproof sealing
Real-world insight (from Reddit):
Waves can cause rapid ON/OFF switching if not stabilized

Pro Tip
For a fully automatic water system:
Float Switch + Relay + Motor Starter
This ensures: Automatic tank filling Motor protection
