There are 4 types of Level Switches based on the nature of measurement.

Float Switches: Use a buoyant float to open or close a circuit when the liquid level changes.

Conductive switches detect levels based on the liquid’s conductivity, making them excellent for water or other conductive liquids.Optical switches use light beams and sensors to detect the presence of liquids at a predetermined level.Capacitive switches detect level changes based on capacitance changes in the surrounding medium
