Abstract

The invention relates to supporting a switch rail of a switch having a projecting leaf spring which can be pretensioned to the switch rail and on which the switch rail is displaceably arranged. Low friction and easy adaptation to the mounting position is possible in that the leaf spring is adjustably arranged in its longitudinal direction in a guide body which can be fastened to the stock rail.
