ABSTRACT:
A building block is provided having side walls and a top face with two rows of coupling pins on the one side of the top face and counter-coupling tubes on the other side for mechanically coupling two such building blocks by means of a clamping action. On their side faces, the coupling pins have electrically conducting regions, which extend over an angular range. The angular range of one row being turned by 180.degree. relative to those of the other row. All the conducting regions are connected to a contact bar, which is arranged on the side of the counter-coupling tubes along one side wall. When two building blocks are coupled arbitrarily, at least one conducting region of each row of coupling pins of the one building block makes contact with a contact bar of the other building block in such a way, that a short circuit cannot occur in the two electrical circuits assigned to each row of coupling pins or each contact bar.
