A switch arrangement includes three identical insulating support frames in the tubular insulating housings of which one vacuum switching tube each is arranged. Parallel insulating wall elements, at which support elements are molded for drive parts of a spring force drive, project from the insulating housings. An output shaft of the spring force drive is supported at all insulating wall elements while the remaining drive parts are arranged at the insulating wall elements of the center insulating support frame.
