Abstract
Conventional operating elements are relatively expensive to manufacture. For this reason, the invention provides an operating element that is easy and economical to manufacture. This is achieved in that an interior formed by the housing is designed in the shape of a spherical segment on whose walls are arranged contacts, and in that a contact carrier is affixed to the lever in such a way that it is supported in the spherical segment.
