Float Switch Water Controller Level Sensor 

The Float Switch is a water level control device that utilizes either micro-switches or mercury switches for its output. Once the fluid reaches the designated control point, the cable float switch will move up or down, causing the internal ball to roll and activate the micro (mercury) switches. This will then send a contact signal to turn on or off the pump, achieving the desired liquid level control.
