Abstract

The invention relates to a switching device for a parking brake, especially a commercial-vehicle parking brake, with a handle that can be moved between a pulled position for engaging the parking brake and a pushed position for releasing the parking brake, and to such a parking brake. The handle is subjected to a preload force toward a central position when it is in the pulled or pushed position. Depending on the position of the handle, an evaluation device outputs different control signals for an actuating device of the parking brake.
