ABSTRACT:
A switch point for a toy cog railway which has smooth tracks with a centrally disposed gear rod comprising a shifting device with a curved and a straight gear rod piece for the given driving direction. The shifting device which supports these gear rod pieces is laterally displaceable with respect to the track direction. Each obtusely travelled end segment of the switch point is provided with a tongue-like actuating element displaceably disposed in a longitudinal slot of the solid gear rod of the corresponding end segment having an upwardly extending nose. In the outermost position of the actuating element the nose protrudes beyond the gear rod and in the inner position thereof it is lowered to the level of the gear rod. Each actuating element is coupled to a rotating mounted disk by way of pivoted levers, which in turn are coupled with the shifting device. A vehicle which travels on the switch point actuates the nose, if the same protrudes.
