111- URDU Water Level Fill Switch
$16.95 – $66.95
This circuit is pulled from the URDU Basic Electronics book. It uses a float switch (ball switch) inside a container. One end of the float switch is secured to the container and as the container fills with water the other end of the switch rises. When the liquid level is high enough, the ball inside the switch rolls down and contacts the leads. Completing the circuit.
