A float switch is a device used to sense the level of liquid within a tank.
The switch may actuate a pump, an indicator, an alarm, or other device.
It can be easily converted from normally open to normally close by inverting the float.
Note: because the current that the switch can carry is little (0.5A), you must use a relay when it is connected by a load which is not included here.
