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.
