The switch is constituted by a profiled cradle forming the housing of a movable tongue-rail (18) for deviation and constituted by a profiled body (20) constructed by machining by removal of swarf. In order to reduce the machining waste and to improve the reliability of movement of the tongue-rail, the body (20) is bolted between a stock-rail (22) and an opposite rail (24), both deprived of their adjacent foot over the entire length of the body (20) and the upper surface of the body (20) supporting the movable part of the tongue- rail (18) is profiled so as to present flat pillow blocks (28) for support of the tongue-rail (18) alternating with recesses (30) machined in the body (20).
