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.

A receiving module is disclosed for building into a switching cabinet, with a primary circuit mating contact element. To improve the coupling of a power switch, especially a low-voltage power switch, to a receiving module, it is proposed in at least one embodiment that the receiving module also has a communication mating contact element, wherein the receiving module can directly receive a power switch, so that a primary circuit contact element of the power switch is directly electrically-conductively connected to the primary circuit mating contact element and a communication contact element of the power switch is directly electrically-conductively connected to the communication mating contact element, wherein the communication mating contact element is arranged in relation to the primary circuit mating contact element such that, in a first receiving position of the power switch in the receiving module the communication contact element is electrically-conductively connected to the communication mating contact element and the primary circuit mating contact element is not electrically-conductively connected to the primary circuit contact element and in a second receiving position of the power switch in the receiving module the primary circuit mating contact element is directly electrically-conductively connected to the primary circuit contact element and the communication mating contact element is directly electrically-conductively connected to the communication contact element.

A switching device includes a switching appliance, a cap, at least one connecting device for firm connection of the switching appliance to the cap, and a monitoring device. In at least one embodiment, the monitoring device includes a sensor and a tripping element, whose position is variable after connection and which, when the switching appliance is ready to operate, is located in a position in which the tripping element can be detected by the sensor, the monitoring device further including a signal unit which is connected to the sensor and is used to signal operational readiness once the sensor has detected this.
