| 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° 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.

I claim:
1. A toy building block having on one face thereof at least one row of mechanical coupling pins and opposite thereto mechanical counter-coupling sockets, at least a plurality of said coupling pins in said row having electrically conducting and electrically insulating regions angularly spaced from each other, said electrically conducting region of each of said pins in said row being disposed at the same angular orientation, and at least one contact member within said block and forming a portion of said socket, said contact member being electrically connected to said electrically conducting regions of a plurality of coupling pins in said row and having electrically conducting surfaces extending in a direction parallel to the longitudinal direction of said row of coupling pins.
