Abstract
By applying pressure created by a forced guidance of a sled (11) to contact springs (12-19) carried by the sled, a reduced contact friction upon insertion, as well as upon removal, of a chip card (3) results. This forced guidance is achieved by having a cut-out (7) in a circuit board (5) in which the sled is shoved by the inserted card to be guided by double slot guides (9)on each side of the sled.
