System for a presentation, sales or exhibition stand and/or for store fitting, as well as current-carrying wall member in such a system

A method to manufacture a wall member for a system that includes

• a current-carrying wall member;
• and
• a current collector for an electrical device, which is configured to be mounted on the wall member;
• wherein the wall member comprises a carrier plate having a front side and a back side;
• wherein the wall member comprises first electrical conductor tracks of a first polarity and second electrical conductor tracks of a second polarity, wherein the first and second electrical conductor tracks are arranged alternately at least in sections;
• wherein the first electrical conductor tracks and the second electrical conductor tracks are arranged on the front side of the carrier plate,
• wherein the current collector comprises a plurality of at least two contact needles, wherein the current collector is adapted to be attached to the wall member such that at least one of the contact needles contacts one of the first electrical conductor tracks and at least one other of the contact needles contacts one of the second electrical conductor tracks;
• and
• wherein the wall member comprises a first electrical terminal contact and a second electrical terminal contact, wherein the first electrical terminal contact is electrically conductively coupled to the first electrical conductor tracks, wherein the second electrical terminal contact is electrically conductively coupled to the second electrical conductor tracks, and wherein the first electrical terminal contact and the second electrical terminal contact are arranged on the back side of the carrier plate,
• the method comprising:
• providing the carrier plate, wherein the carrier plate has the front side and the back side;
• applying first electrical conductor tracks of the first polarity and second electrical conductor tracks of the second polarity;
• applying the first electrical terminal contact and the second electrical terminal contact on the back side of the carrier plate.
