What is meant by the "Three positions" switching function implemented in SM6-24 switch / disconnectors?

The three-position switching of SM6 switch/disconnector/earth switch function means that the main contacts can be ONLY connected to ONE of the three positions (Closed – Opened – Earthed) at a given instant which represent a natural interlocking system that prevents incorrect operation that enhances the operator safety concept.
