<p>A building element (1) with coupling studs (2) and complementary coupling means (3) for mechanical coupling of the building blocks is provided with electrical contact areas. The contact areas are connected to their respective current paths, and to avoid short circuiting between the current paths when the building elements are coupled together in various mutual directions, the contact areas might be placed as a multi-plug in connection with each coupling stud (fig. 3). Such a multi-plug with contact areas (4-11), however, would be very expensive to produce, but when, according to the invention, the contact areas are distributed over a large number of coupling studs, typically four coupling studs with a predetermined spatial location, a significantly reduced number of contact areas is sufficient for coupling stud, so that the building block is very easy and inexpensive to produce. For example, the coupling areas may be positioned as appears from fig 4, from which it will be seen that two contact areas per coupling stud are sufficient to ensure contact between the current paths of the building block (1) without short circuiting. Additionally, some coupling areas may be omitted so as to provide an embodiment which is even more inexpensive to produce, and which in practice exhibits a sufficient number of coupling posibilities where the current paths are interconnected without short circuiting of them.</p> |
