Abstract: An operating element for the engaging and extraction of planar sub-assemblies, with a display element in the operating lever, a front element for a planar sub-assembly with operating element and component support for accommodating planar sub-assemblies.

Abstract: An operating element for engaging and extraction of a planar sub-assembly with an end-piece prepared for connection to the planar sub-assembly. An operating lever rotatably mounted on the end-piece has at least one grip section and a locking element which may be displaced, in particular shifted between at least two switch positions, whereby in a first switch position, the operating lever is held in a state with the planar sub-assembly in an engaged position and in a second switch position, the operating lever is released for extraction. The operating lever has at least one combined display/switching element.

Abstract: An actuating element for inserting and removing a flat module by leverage, the element having an end piece designed to be connected to a flat module. An actuating lever, which is pivotally mounted on the end piece, has at least one grip section and a locking element, which can be displaced, particularly slid between two connection positions. In a first connection position, the actuating lever retains the flat module in its inserted state and in a second connection position, the actuating lever is released to remove the module by leverage. The actuating element has a connecting element, which is activated in the first connection position of the locking element, which can be displaced into a third connection position, in which the actuating lever is retained in the first position, corresponding to the inserted state of the flat module and in which the connecting element is disconnected.

Abstract: The invention relates to an actuating element for inserting and removing a flat module (2) by leverage, said element comprising an end piece (1) designed to be connected to a flat module (2). An actuating lever (4), which is pivotally mounted on the end piece (1), has at least one grip section (5) and a locking element (6), which can be displaced, in particular, slid between two connection positions (A, B). In a first connection position (A), the actuating lever (4) retains the flat module (2) in its inserted state and in a second connection position (B), the actuating lever (4) is released to remove the module by leverage. The actuating element has a connecting element (25), which is activated in the first connection position (A) of the locking element (6). The latter (6) can be displaced into a third connection position (C), in which the actuating lever (4) is retained in the first position, corresponding to the inserted state of the flat module (2) and in which the connecting element (25) is disconnected.

Abstract: The invention relates to an operating element for the engaging and extraction of planar sub-assemblies, with a display element (7) in the operating lever (4), a front element for a planar sub-assembly with operating element and component support for accommodating planar sub-assemblies.

Abstract: The invention relates to a front system for a flat module comprising an integrated electric display clement (28) and a lever pull handle (13) with an end piece (3) for a front system.

Abstract: The mounting rack contains transverse rails (1, 31), at least one front element (29), and at least one spring contact strip (10; 38). The contact strip has a retaining portion (11) for fitting on an end face (21, 22) of the transverse rail and contact springs (14) which are connected to the retaining portion and have spring limbs (15) which are angled off in a direction away from the interior of the mounting rack, such that these spring limbs (15) extend in a direction generally coincident with the longitudinal side (54) of the front element the spring movements of the spring limbs (15) are generally in the same direction as the insertion and withdrawal movements (24, 48) for the printed circuit board assembly fastened to the front element.

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.

Abstract: 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.
