The front system contains one lever pull handle (1) preferably both at the upper and the lower corner of the front element (38, 11). A latching slide (10) is mounted in each of these lever pull handles (1). Furthermore, a latching mechanism (22, 23, 26) is provided, which engages on the latching slide, as well as on a stressing mechanism (35) and on the front element (38, 11) such that the lever pull handle is held resting against the front element (38, 11) in a locked position. The latching mechanism can be unlocked again by a movement of the latching slide which is exerted on a pushing region (27) of the latching slide and is directed in a direction opposite to the pre-stress (52, 53) of the stressing mechanism.

[ What is claimed is:] [1.] Front system for electrical printed circuit boards supported in a mounting rack via opposing pairs of adjacently arranged guide rails, comprising:a) a front element fitted on a front end face of a printed circuit board;b) lever pull handles fitted respectively to an upper corner and to a lower corner of said front element, each of said lever pull handles being mounted pivotably about a fulcrum in a plane of the printed circuit board and having an engagement region on an end facing a respective corner of said front element, wherein the engagement region is supported on the mounting rack when the printed circuit board is levered into or out of the mounting rack;c) a latching slide mounted in each of said lever pull handles, each of said latching slides having a pushing region at an end of said respective lever pull handle that is located opposite the engagement region;d) stressing mechanisms, each of which, respectively, exerts a pre-stress, directed toward the pushing region, on said latching slide and holds said latching slide in an original position; ande) latching mechanisms arranged at the upper corner and the lower corner, respectively, of said front element, each of said latching mechanisms engaging on said latching slide, said stressing mechanism and said front element,wherein said lever pull handles are held in locked positions when each said lever pull handle is pivoted toward said front element of the printed circuit board, andwherein said latching mechanisms each are unlocked by a force on said latching slide which is exerted on the pushing region of said latching slide and is directed in a direction opposing the pre-stress of said stressing mechanism.
