What is a float level switch?

Basically float level switch is the most widely used level switch. A float level switch is either mounted or floating on the media. Suppose it floats on a liquid. When the float is in upright position or above upright position, it means the level is correct. Now, let's say the float went below the upright position. This means the level has dropped and due to this, the switch will change its electrical output. The switch has a magnet with a reed switch. It is the switch which gives the electrical signal. The switch is moved by a magnet which changes its position as per the floating level sensed.
