Abstract
The front system has an upper and a lower end piece (5) which are fastened to the upper and lower front corner region (3), respectively, of the printed circuit board assembly (3). An upper and/or a lower lever pull handle (19), which is fitted to the upper and/or lower end piece respectively, is used for levering the printed circuit board assembly into and out of the monitoring rack. A latching mechanism (25) is provided to fix the lever pull handle in the appropriate position when the printed circuit board assembly has reached the point where it has been fully inserted into the mounting rack. A switching element (31) is integrated in the upper and/or lower end piece in such a manner that the switching element is actuated by the lever pull handle when it is in its fixed position. By this means, the printed circuit board assembly can be electrically enabled. The invention has the advantage that, as a result of its integration into the lower and/or upper end piece, the switching element can be moved to an accurately definable position. It is thus possible to permanently and reliably actuate the switching element with the lever pull handle even when an actuator of the switching element has only a small switching path.
