Railway switch for Vignoles rails, comprising a frog tip and a pair of wing rails arranged for swivelling movement, one of said wing rails engaging the frog tip in its end position and being supported in this position in direction of engaging the frog tip by means of movable supporting members resting against the railway sleepers, noting that the movement of the supporting members and of the wing rails is being effected in mutual dependence, that the supporting members are guided on the railway sleepers in longitudinal direction of the corresponding wing rails and are cooperating with abutments protruding from the wing rails and preferably being fixed to the web of the wing rails, and that the supporting members are formed of one supporting rod for each associated wing rail, said supporting rod comprising, in addition to the supporting surfaces serving for supporting the abutments, recesses giving free the wing rails, characterized in that the push-rod serving the purpose of switching over the railway switch comprises abutments into the shifting path of which a portion of the supporting rods or a part rigidly connected to the supporting rods is protruding as long as the supporting rod considered assumes a position in which the supporting rod is giving free the abutments of the associated wing rail, noting that the supporting rod considered or the part rigidly connected to said supporting rod, respectively, gives free the shifting path of these abutments only when the supporting rod considered assumes its supporting position.
