Abstract

A locking apparatus is disclosed for an electromechanical switching device having a manual actuation option. Furthermore, such a switching device is also disclosed. A robust, mechanically simple locking apparatus is provided which can be operated without a tool, as well as a correspondingly embodied switching device. The locking apparatus of at least one embodiment includes a combination of few interacting construction elements attuned to one another in terms of structure and function. In this apparatus, a locking element assumes a double function, by, on the one hand, securing the connection of the locking apparatus with the switching device and on the other hand preventing a change in position of the actuation element of the switching device.
