    • 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.
    • 前置系统具有分别固定到印刷电路板组件(3)的上下角区域(3)的上端和下端件(5)。 分别安装在上端和/或下端的上部和/或下部拉杆拉手(19)用于将印刷电路板组件拉入和离开监视架。 当印刷电路板组件已经到达已经完全插入安装架的位置时,提供一个闭锁机构(25)来将杠杆拉手柄固定在适当的位置。 开关元件(31)以这样的方式集成在上端和/或下端件中,使得当杠杆拉手处于其固定位置时,开关元件被致动。 通过这种方式,印刷电路板组件可以被电启用。 本发明的优点在于,由于其集成到下端和/或上端件中,开关元件可以移动到精确定位的位置。 因此,即使当开关元件的致动器仅具有小的开关路径时,也可以通过杠杆拉手来永久且可靠地致动开关元件。
