What is a paddle type level switch?

Basically the paddle type level switch is a very simple concept and works on the movement of the paddle. A paddle is installed underneath the sensor setup, which is driven by a small electric motor. In the absence of any media, the paddle will move freely. If exposed to any medium, more force will be needed to move the paddle. It may also happen that the paddles stop rotating. This rotational change alters the electrical output.
