1. A device for switching at least two partial gear mechanisms, namely a first partial gear mechanism and a second partial gear mechanism, each having at least two gear stages, comprising: an actuator connected for drive purposes to a rotatable component; a first switching device for switching the first partial gear mechanism and a second switching device for switching the second partial gear mechanism and which are arranged on the rotatable component, wherein the first switching device and the second switching device each comprise:
a sleeve which is arranged rotationally fixedly but axially movably on the rotatable component,
a shift gate which is formed on the sleeve,
a guide element which is arranged fixedly relative to the device and engages in the shift gate,
a shift fork which is arranged axially movably on the sleeve and engages in a sliding collar of the respective partial gear mechanism, and
an elastic storage arrangement which can be loaded by the sleeve via a first carrier element arranged fixedly on the sleeve, in order to transmit a load to the shift fork.
