The present invention relates to a galvanic switch for electrically making or breaking one cross-point among a plurality of cross-points in a three-dimensional switching matrix. The switch includes electrical contact lines (16), first links (17) which extend perpendicular to the contact lines, and second links (18) which extend perpendicular to both the contact lines and the first links. At each cross-point, there is located a contact element (10) in the form of a spherical element for making and breaking the electric contact respectively. The contact elements either make or break the cross-point depending on whether the coupling element is conductive (15) or non-conductive (14), and are manoeuvered by manoeuvering elements (11, 12, 13). In a first selection, first manoeuvering elements (11) are manoeuvered so as to move all coupling elements simultaneously in a chosen first plane (x-y) of cross-points, where-after second manoeuvering elements (12) are manoeuvered so as to move simultaneously all of the coupling elements moved by the first manoeuvering element (11) in the intersection between the first selected plane and a selected second plane (y-z) of cross-points. Manoeuvering of third manoeuvering elements (13) for moving the coupling element moved by the first and the second manoeuvering elements in the intersection between the selected second plane (y-z) and a selected third plane (x-z) is utilized as a coupling function for bringing into the cross-point a coupling element of opposite kind to the coupling element already present in the cross-points. |
