optical level switch is a type of point level sensor used to detect the presence or absence of liquid at a specific level in a tank or container.
An optical level switch uses infrared light:
It has an IR LED + phototransistor inside a small prism tip
When the tip is in air → light reflects back to the receiver
When immersed in liquid → light refracts (escapes) into the liquid
This change triggers an ON/OFF switching output �
