A contact arrangement is used in a card (1) having on a surface (1a) printed circuits and/or lines. One or more contact rollers (6, 7, 8) are so arranged as to be capable of movement relative to the aforementioned surface (1a) and in such a way that each roller is capable of interacting with the parts of the circuit or the lines so as to close, switch and/or interrupt, depending on the positional displacements, the electrical contact between parts of the circuit and/or parts of the lines. |
