1. A switching disk for contacting windings of a stator of an electric motor, which windings are arranged around an axis of rotation, with a printed circuit board of the electric motor,
wherein the switching disk has an annular support structure circumferentially extending around the axis of rotation and multiple contact arrangements for contacting the windings with the printed circuit board, which are held by the support structure,
wherein the contact arrangements are each formed by a winding contact for contacting one of the windings, a printed circuit board contact offset therefrom in the radial direction for contacting the printed circuit board, and a coupling element extending in the radial direction and electrically connecting the winding contact to the printed circuit board contact; and
wherein, for each of the contact arrangements, the support structure has a respective receiving space in which the respective winding contact, the respective printed circuit board contact and the respective coupling element are held, in particular in a detachable manner, and a fastening element is arranged in the receiving space, the fastening element designed as a latching hook configured to hold the winding contact and/or the printed circuit board contact and/or the coupling element in the receiving space.
