Abstract
A first printed circuit board (principal printed circuit board) is placed onto a housing frame having a stepped contour in a front edge region of the housing. The first printed circuit board is introduced into a receptacle of the frame provided with an entry bevel and, when put in place, is automatically interlocked by interlocked elements preferably arranged at an opposite side. Additional printed circuit boards can be inserted into guide elements present at the backplane, being inserted under this first printed circuit board. Their ultimate position is compelled by corresponding holder elements. In this ultimate position, each printed circuit board that is introduced and lies parallel to the backplane is interlocked by an interlock element that takes effect in this position. The additional, second printed circuit boards can be inserted independently of the first printed circuit board and are preferably provided for optional add-ons.
