摘要： A railway switch mechanism including first and second switch blades, wherein a switch point of each of the first and the second switch blades is vertically displaceable by means of a displacement mechanism in order to establish a switch movement in the respective switch point, wherein the respective displacement mechanism includes at least one pair of cooperating wedges having a lower wedge and an upper wedge, wherein at least one wedge of the at least one pair of cooperating wedges is arranged to be displaced in a direction substantially parallel to a longitudinal direction of the switch blade or parallel with a longitudinal direction of the switch mechanism, and wherein the switch blades are elastically deformable in the vertical direction or pivotally connected by hinged joints to first and second closure rails respectively for enabling the vertical displacement of the switch blades.
