A float switch is a device with which you can control a pump. For example, you need to periodically pump the water out of the tank when it is filled to a certain level, the float starts the pump, and the pump in turn pumps out the water and stops. Or you need to periodically fill the tank, which is emptied to a certain level, the float will start the pump, and the pump in turn will fill the tank and stop. The Pedrollo Small 3 float switch has two significant advantages: it has a dual function (filling and emptying) and a relatively low price. It can be applied to both filling and emptying. How to implement its electrical connection for these cases in this video.
