The high-power switch ( 1 ) according to the invention, with at least one switch pole ( 2 ) for guiding and switching an electric current which flows in one current flow direction when the switch is in the closed state, with the at least one switch pole ( 2 ) containing an inner conductor ( 3 ) which carries the current and containing an outer conductor ( 4 ) which is connected to ground potential (G) and carries a return current in the opposite direction to the current, with the outer conductor ( 4 ) being in the form of a housing ( 4 ) which surrounds the inner conductor ( 3 ), is characterized in that a cooling rib arrangement ( 5 ) which contains cooling ribs ( 9 ) is arranged on the outer conductor ( 4 ). At least some of the cooling ribs are advantageously arranged on a separate part of the housing ( 4 ), which is not the same as the part ( 15 ) of the housing ( 4 ) which is at a minimum distance from the inner conductor ( 3 ). The cooling rib arrangement ( 5 ) advantageously has cooling ribs both outside the housing ( 4 ) and inside the housing ( 4 ).
