Abstract

A building block is provided comprising a support part, two zig-zag shaped conductive tapes connecting a series of coupling pins with conductive surfaces positioned on the support part, and a cover plate. The coupling pins which extend through openings in the cover plate define two separate electrical circuits with the coupling pins arranged in two rows and the pins of one row being displaced by one pin with respect to the pins of the other row. A prong extends from each of the coupling pins to the inner sidewall of the support part. The building block may be connected to another similar building block with the electrical circuits separated in a short-circuit proof fashion.
