Load module for inserting into a tube of a three-dimensional supporting tube structure of a furniture system

A load module for insertion into a tube of a three-dimensional load-bearing tube structure of a furniture system, the load module comprises:

• an elongate housing;
• two contact elements for making electrical contact with the load module, which contact elements have different polarities, are arranged on an outer side of the elongate housing, the contact elements are arranged in such a way that, when the load module is in an inserted state, the contact elements make contact in a radial direction with two contact areas of different polarity which are arranged in an interior of the tube and the elongate housing has a region which is central in a longitudinal direction, which region has at least one projecting element, and also regions which are on an outside in the longitudinal direction;
• the load module can be inserted into a tube of the tube structure, which tube is provided with an elongate cutout, in such a way that the at least one projecting element interacts with an edge of the cutout, and the outer regions bear against an inner casing of the tube in regions which adjoin the cutout;
• and
• a first of the contact elements is arranged in one of the outer regions, in a first circumferential position.
