What Is a Cable Float Switch?
A cable float switch is a liquid level controller that operates using a floating body connected to an electrical cable. As the liquid level rises or falls, the float tilts at a specific angle, activating an internal micro switch to output an ON/OFF control signal.
Cable float switches are widely used for:
- Pump control
- High and low level alarms
- Tank liquid level monitoring
- Automatic drainage systems
- Wastewater and sewage systems
Their simple structure and reliable operation make them one of the most common liquid level control solutions worldwide.
