A metal enclosed multi-phase high voltage switching arrangement filled with compressed gas and provided with an interior protective wall between the bus bar chamber and the switch chamber. The electrical connection between the two chambers is established via gas tight passages or passthroughs arranged diagonally in the protective wall, with the passages being disposed, in one direction, at the spacing between the bus bars and, in the other perpendicular direction, at the spacing of the poles of the high voltage power or load switch in the switch chamber. Straight connections without crossovers are provided in the bus bar chamber between each bus bar and the associated passage via the respective disconnect or three-way position bus bar switch, while the connecting lines in the switch chamber from the passages to the respective poles of the high voltage switch extend in mutually parallel planes, here again without cross-overs.
