| 1. A switch comprising a maintrack and a branch track, each one of said tracks comprising
a tongue rail and a respective stock rail, said tongue rail being movable into abutment on said respective stock rail, wherein
at least one of said stock rails (1), in its region of abutment on the tongue rail (2), is formed to have a reduced rail head width as compared to a region located outside said region of abutment, wherein the
rail head width, starting from a tip (3) of a tongue of said tongue rail (2), decreases as far as to a point (4) at which a carrying wheel comes into lateral contact with the tongue rail (2) and increases in a region following said point (4), and
the tongue rail (2) is reinforced in cross section towards the stock rail (1) in correlation with the reduction in the width of the stock rail head.
