The disclosure concerns a railway switch mechanism (100) comprising a first and a second switch blade (141; 142), wherein a switch point (145a; 146a) of each of the first and the second switch blade (141; 142) is vertically displaceable by means of a displacement mechanism (200a; 201a) in order to establish a switch movement in the respective switch point (145a; 146a), wherein the respective displacement mechanism (200a; 201a) comprises at least one pair of cooperating wedges (311 a, 312a, 313a, 314a, 315a, 311 b, 312b, 340a, 341a, 342a, 343a) having a lower wedge (211a, 211b) and an upper wedge (212a, 212b), wherein at least one wedge of the at least one pair of cooperating wedges (311a, 312a, 313a, 314a, 315a, 311 b, 312b, 340a, 341a, 342a, 343a) is arranged to be displaced in a direction substantially parallel to a longitudinal direction of the switch blade (141, 142) or parallel with a longitudinal direction (L) of the switch mechanism, and wherein the switch blades (141; 142) are elastically deformable in the vertical direction or pivotally connected by hinged joints to first and second closure rails (170, 171 ) respectively for enabling the vertical displacement of the switch blades (141; 142). The disclosure also concerns a corresponding switch frog, an assembly of such a switch blade switch mechanism and switch frog, and a method for operating such an assembly. |
