Auxiliary module for an electrical switching device, and associated switching device and monitoring system

An auxiliary module for an electrical switching device, the electrical switching device comprising at least an input, an output, and a first housing, wherein the electrical switching device is configured to switch between a first configuration in which an electric current is allowed to flow between the input and the output and a second configuration in which the flow of the current between the input and the output is blocked, the first housing defining a space for receiving the auxiliary module, the space containing at least one signalling member configured to transmit first information relating to a state of the electrical switching device to the auxiliary module when the auxiliary module is accommodated in the space,

• wherein the auxiliary module comprises a controller configured to generate a message containing second information representative of the transmitted first information and a radiofrequency communication module configured to transmit the message, via a radiofrequency data link, to a device remote from the electrical switching device, and
• wherein the auxiliary module further comprises a second housing, a first printed circuit board, a second printed circuit board and a mobile element, the second housing defining a chamber that accommodates the first board and the second board, the first printed circuit board carrying the controller and extending in a first plane, the second printed circuit board being connected to the first printed circuit board and extending from the first printed circuit board in a direction perpendicular to the first plane, the second printed circuit board carrying an electrical circuit connected to the controller, the mobile element being configured to be moved in translation by the signalling member in a direction of translation between a first position in which the electrical circuit is open and a second position in which the mobile element closes the electrical circuit, the state of the switching device being indicated by the open or closed state of said electrical circuit.
