Abstract
A switch for connecting a main track girder selectively to any of a plurality of branch track girders includes a plurality of movable girders with articulations between adjacent movable track girders and between the main track girder and one of the movable track girders adjacent thereto, forming a stepped curve. The track girders have main rails fixedly secured thereon, respectively, for guiding a vehicle and for forming the stepped curve according to the arrangement of the main track girder and the movable track girders. A short intermedial rail is provided between the adjacent main rails. The short intermedial rails have both ends connected to the main rails on adjacent main track girders and adjacent movable track girders with relatively variable angles.
