- the control bar 9 is shown in FIGS. 2 and 3 in isolation. Accordingly, the control bar 9 is plate-shaped with the two front, staggered shape portion 13 and frame portion 14 designed.
- the material structure of the control bar 9 is shown in FIG. 4. It follows that the control bar 9 front as a decorative layer has a metal foil 23 which is provided on a base body 25 made of plastic material.
- the metal foil 23 can be back-injected with the plastic material of the main body 25 in a plastic injection molding process.
- the metal foil 23 can be inserted in the production of the control bar 9 as a still planar semi-finished or preformed molded part in an injection molding chamber of a corresponding injection molding tool and then back-injected with the plastic material of the base body 25.
- the metal foil 23 may preferably be formed of aluminum material.
- the metal foil 23 may have a material thickness in the order of 0.2 mm, while the main body 25 may have a material thickness in the range of 2 mm in order to ensure sufficient dimensional stability of the control panel 9.
- a circumferential edge web 27 is integrally formed on the side of the main body 25 facing away from the metal foil 23, as shown in FIGS. 3 and 4.
- the edge web 27 is approximately offset by the material thickness of the mounting opening 21 of the sheet metal housing part 17 surrounding sheet metal parts of the outer edges 29, 30 of the control bar 9, whereby a in the device side and -hochraum x, z play-free mounting the control bar 9 is enabled.
