ABSTRACT:
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).
