ABSTRACT:
A connection member between a given number of n distinct parallel paths (V.sub.1 to V.sub.n) and a common path (V.sub.0) comprises, for establishing the 2.sup.n distinct combinations of connections between this common path and the n distinct paths, 2.sup.n-1 connection arms distributed along a circle around the central part of the member in 2.sup.n-1 positions among 2.sup.n possible positions. The 2.sup.n-1 positions are chosen such that the successive switching steps along a circular path of this member establish successively each of these 2.sup.n distinct combinations of possible connections between the common path and the n parallel paths.
