Key
Electromechanical level regulator

The Key level regulator is a float switch which allows electrical equipment to start and stop automatically (usually pumps, but also electric control valves, alarms, etc.) when a prefixed level has been reached. It is highly reliable thanks to a multiple closure device on the fairlead.
This is the most universally used float switch in the world for the automation of pumps and is used directly by pump producers.
The models with cable 3X1 or cable 4G1 can be used for the filling or emptying function according to the cables that have been connected. The models with 3G1 cable (with ground) or UL cable are set for one function only, and that is for filling or emptying.
The minimum working distance between the Key level regulator and the fixing point is 20 cm.
