to time positionally during the translational movement of the contact element 53 in the direction of the longitudinal side 69 of the card several such contact elements 53 in a switch element switch slider 50 52 are placed at predetermined distances so that they guided in parallel connect the contact elements 62 on the upper surface and the underside in the identical configuration respectively so that the switch during its movement simultaneously connects several contact elements 62 opening or closing them and in this way can perform complex switching functions in the switch elements 50 52 a plurality of cuboid hollow spaces for example 51 have been provided into which the contact springs 53 can be inserted these hollow spaces are formed such that each single spring 53 has a sufficient amount of mechanical freedom in the movement direction vertically to the board 60 in order to prevent measurement variations regarding the position of the board 60 themselves and those of the moving switch strap 50 from having any effect on assurance of contact i e the position of the contact elements 53 in this way it is assured that the position of the contact elements 53 is exclusively determined by the geometry of the board 60 and not by the position of the switch strap 50 the switch strap 50 is formed in such a way that during a displacement of the switch strap in the direction of the longitudinal side 69 of the board 60 the contact elements 53 are carried along so as to reach the other switch positions guided in parallel in actuality.
