The invention relates to switch gear comprising at least one group of n power switches (4), which extend substantially in a longitudinal direction perpendicular to the front of the switch gear, at least one busbar compartment (13,13') containing n busbars (14,14') for each group of n power switches (4), which busbars (14,14') are positioned parallel to the front, wherein each busbar compartment (13,13') is enclosed by at least four walls, two of which are perpendicular to the front, at least one group of n busbar disconnecters (3,3'), for making and breaking contact between busbars (14,14') and respective output terminals (21) of the power switches (4), wherein the output terminals of the power switches (4) are constructed as coupling elements (21), to each of which a linkage (24) is connected and a further linkage (24') can be connected in an opposing direction perpendicular to the longitudinal direction, wherein the n busbars (14,14') extend along one of the walls perpendicular to the front. Connection between busbars and corresponding output terminals is achieved through front and rear switch blades disposed on a rotatable drive rod. In a contact position, the front switch blade contacts the output terminal through the linkage, and the rear switch blade contacts the busbar. When the rotatable drive rod is rotated out of this position, contact is broken.
