Abstract: A switch gear with at least two gear stages is provided. At least one gear stage is configured as a switching stage, whereby at least one switching stage is formed by a coaxially nonrotatable sunwheel on a drive shaft, by at least one planet carrier carrying one planet wheel and by at least one ring gear meshing with the planet wheel on the inside, which is held fixed in its housing, and by a cam disk for the actuation of switching elements. The cam disk is provided with a female spline which exhibits approximately the identical pitch circle diameter as the female spline of the ring gear, whereby the female spline of the cam disk exhibits a number of teeth different from the female spline of the ring gear and whereby the cam disk, by means of the female spline, meshes with at least one planet wheel of the switching stage. The switch gear may be used, for example, as a limit switch of cranes.
