Abstract

In order to form a three position load isolating switch (1) for medium voltage switchgear assemblies with an extinguishing contact system for extinguishing an arc during a switch off process of the switching device (1) and having a main contact system which is connected in series with the extinguishing contact system for forming a dielectric isolating gap in an open state of the main contact system and an extinguished arc and having an earthing contact system which three position load isolating switch has a compact structure the invention proposes that the main contact system has a first fixed contact (2) and a second fixed contact (3) which fixed contacts are situated diametrically opposite one another and has a moving contact (4) which can be rotated by means of a rotary support (5) which is arranged centrally between the first fixed contact (2) and the second fixed contact (3) and which has the extinguishing contact system integrated in it.
