An XYX cross-connect switching matrix (200) is provided for use in telecommunications apparatus. The matrix (200) comprises first (10), second (20) and third (30) arrays of parallel conductor tracks (11-14, 21-28, 15-18). The parallel conductor tracks (21-28) of the second array (20) are oriented perpendicular to the conductor tracks (11-14) of the first array (10) and to the conductor tracks (15-18) of the third array (30). The first (10), second (20) and third arrays (30) each lie in planes parallel to and spaced from one another, with the second array (20) being located between the first (10) and third (30) arrays. A first set of electrical contact sleds (41) is provided between the first (10) and second (20) arrays, while a second set of electrical contact sleds (42) is provided between the second (20) and third (30) arrays. These sleds (41,42) enable any X conductor track (11-18) in the first (10) or third (30) array to be electrically connected to any Y conductor track (21-28) in the second array (20).
