The optical liquid level switch uses the principle of total reflection in a prism. When the sensor is surrounded by air, the angle of incidence is greater than the critical angle and thus total reflection occurs. Totally reflected light will be transmitted to the receiver. Conversely, when the sensor is surrounded by liquid, due to the refractive index of the liquid and the sensor tip material, almost all light will penetrate the front of the sensor. The receiver can detect and determine a light reflected or penetrated state, and determines the circuit output
