Abstract
A switch for a suspended railway vehicle having two elastic wheels, comprises four rails forming three paths one of which branches off into two other paths. A gap is bounded between the four rails. When the vehicle runs over the switch from one to another path one of its wheels enters the gap and runs without support, and after passing the gap this wheel engages with a portion of one rail of the other path. A plurality of ramps are provided each arranged on a respective one of the above-mentioned portions and so that after passing the gap the one wheel is raised by the ramp to a contact surface of the rail of the other path. At the same time, each ramp includes a transitional portion merging into the rails with a transverse inclination which decreases proceeding in the direction along which the transitional portion merges into the respective rail.
