Abstract
A switch assembly for magnetic levitation railways includes a girder extending in a travel direction (x) and flexible transversely to it is provided with travel way or equipment parts. A rail and a rack are located transversely to the travel direction. A load-bearing frame, receiving the girder, has a rotatably supported carrying wheel braced on the rail and a drive mechanism with a gear wheel meshing with the rack and with a motor intended for driving it. Switch adjustment is effected by displacement of the load-bearing frame along the rail by means of the drive mechanism and a thus-effected flexing of the girder. The girder, the load-bearing frame and the drive mechanism form a solidly joined-together structural unit which as a whole is located displaceably in the travel direction (x) relative to the rail and the rack.
