In electronic apparatus comprising a plurality of printed- circuit boards inserted in a printed- circuit-board magazine, it is ensured that the printed-circuit boards can be installed only in a specific sequence. This is achieved by a movable bolt movable transversely to the parallel slide-in planes of the printed-circuit boards. This bolt comprises retraction surface for one slide-in plane (10) and a detent surface (7) for another slide- in plane so that as a result of the insertion of a printed-circuit board in the one plane, the bolt (1) is displaced so far by the board camming on a retraction surface (5) that the detent surface (7), previously preventing the insertion of a printed-circuit board in the other plane, opens the slide-in plane for the second printed-circuit board.
