Level switches allow you to automatically start or stop devices (pumps, solenoid valves, alarms, etc.) as soon as the desired level is reached in the tank on which the switch is located.

Inside the device there is a micro switch, which opens or closes depending on the level of fluid.

Models with either a 3x1 or 4G1 cable have one NO and one NC contact on that one cable. Once the level rises to the height of the switch, both contacts change their state.
