The invention describes an arrangement for the touch-safe contacting of a busbar system comprising multiple busbars, wherein the arrangement has a touch protection housing made of electrically insulating material comprising receptacles for busbars, wherein the touch protection housing has a base having the receptacles and also a cover, which closes the receptacles and is optionally detachable from the base, having an installation side, wherein the arrangement furthermore has a multipole busbar adapter for the electrical contacting of the busbars, which is installed with an adapter housing on the installation side and for this purpose passes through the cover with at least one retaining foot engaging behind the busbars and also with at least one contact element in each case for every busbar to be electrically contacted.

An in-wall power adapter adapted to receive a voltage is described. The in-wall power adapter may comprise a first plurality of contact elements comprising a first contact element adapted to receive a line voltage and a second contact element adapted to be coupled to a load; a recess adapted to receive a control module; a second plurality of contact elements associated with the recess and comprising a third contact element coupled to the first contact element and a fourth contact element coupled to the second contact element; a switch coupled to receive the line voltage at a first terminal by way of the first contact element; and a connector coupled between a second terminal of the switch and the second contact element; wherein the connector is in a closed position when no control module is in the recess.

An in-wall power adapter adapted to receive a voltage is described. The in-wall power adapter may comprise a first plurality of contact elements comprising a first contact element adapted to receive a line voltage signal, a second contact element adapted to receive a neutral voltage, a third contact element adapted to receive a ground voltage, and a fourth contact element adapted to receive a communication signal; a recess adapted to receive a control module; a switch having a first terminal coupled to receive the line voltage; and a second plurality of contact elements associated with the recess and comprising a fifth contact element adapted to receive the communication signal.

A control module adapted to be attached to a power adapter is described. The control module comprises a plurality of contact elements including a first contact element adapted to receive a line voltage and a second contact element adapted to receive a reference voltage; a first actuator extending from a housing of the control module and adapted to engage with a connector of a power adapter; a second actuator extending from the housing of the control module and adapted to engage with a tamper resistance element of a power adapter; a control circuit adapted to generate a signal; and a third contact element coupled to the control circuit; wherein the control circuit generates to the signal adapted to be routed to the power adapter by way of the third contact element to detect a change in a state of a switch of a power adapter.
