Abstract

A switch device including a switch rail (12), the switch device having at least one stock rail (14), a junction rail (32) and a switch rail support (16), and the switch rail and the connecting rail being interconnected by a weld joint (34). The switch rail support (16) includes a through-opening (36) or a recess beneath the weld joint, the width of the through-opening or the recess being wider than the width of the switch rail (12). Furthermore, the length of the through-opening or the recess allows the junction rail (32) to connect to switch rails of the same or different lengths.
