Abstract

The invention refers to a locking unit, in particular a transmission locking unit. It consists of a coil encircling at least partly an armature space. The coil has a wire that can be energized by electric current. An armature rod projecting out of the armature space and carrying an armature is provided, as well as an operating element locking unit interacting with the armature rod. This holds or releases, depending on the position of the armature rod, an operating element, wherein the armature rod or the armature is held in a first position by a permanent magnet, and a current flow through the wire of the coil compensates the holding force of the permanent magnet, and the armature rod gets in the second position.
