<p>A switching matrix (10) includes at least two parallel circuit boards (11, 13, 15, 17) each having plural conductive traces and multiple matrix holes (20) therethrough arranged to permit traces (21, 22) on one board to be connected to traces (23, 24) on the second board. Connection is achieved by means of a flexible non-conductive circuit jumper pin (40) having a resilient conductive sleeve (47, 49) arranged to extend between an aligned pair of holes in the two boards. The holes are conductively plated to define female contacts to radially compress the conductive sleeve. Circuit jumper pins may be moved between different matrix positions manually or by a pick and place mechanism (50) controlled from a remote location. In one embodiment, connections are made in pairs, there being four circuit boards and two conductive sleeves (47, 49) on each pin, each sleeve interconnecting a pair of traces on a respective pair of boards.</p> |
