The invention relates to a method of producing a multifunctional functional unit with a rigid support structure, in which control elements and/or display elements are arranged behind a transparent surface layer which is continuous over substantially the entire functional unit. The method includes punching a positioning hole in a transparent plastic film with a thickness in the range of 0.1-0.4 mm; positioning the film into an injection mold using the positioning hole, with a corresponding positioning means for engaging in the positioning hole; back-injecting film to form a plastics support on the first side, the injection mold being designed such that, of the plastic film is not back-injected at the control elements and/or display elements, on the second side the plastics film is flooded with a transparent curing casting compound to form a continuous transparent surface layer.

Operating element and method for the production thereof
A method for producing a flexible, three-dimensional coating structure with a surface curvature on the front side and an impression on the rear side for a flexible switch or a flexible user interface. The method is essentially characterized by the following steps: introducing an uncured, transparent casting compound into a compression mold with an impression that forms the shaping of a surface curvature; introducing a counterpunch that penetrates at least partially into the impression, so that the casting compound is distributed in the gap between the shaping of the surface curvature of the compression mold and the surface of the counterpunch and fills this gap; introducing energy into the casting compound, so that the casting compound cures to form a substantially self-supporting, flexible, transparent surface layer with a surface curvature on the front side and an impression on the rear side.
The invention relates to a sliding switch (1) having a group composed of a plurality of individual switch elements (17) which are disposed next to each other and can be actuated directly or indirectly by a manual sliding actuation, comprising a closed coherent mat (2) having elastic properties, in which the group of switch elements (17) is configured in that an individual ram (20) is integrally formed onto a bottom side (10) of the mat (2) at the respective position of a switch element (17), or is fastened thereto, and in that an elevation (23, 36) or depression (18) is formed onto a top side (9) of the mat (2) at the respective position of a switch element (17), or is fastened thereto, wherein the distance (d) between two rams (20, 20') and adjoining switch elements (17) ranges between 2 and 12 mm.
A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.
Disclosed is a button (1) for intermittently electrically contacting at least two conductors located on a circuit board (8) with an electrically conducting contact element (5). Said button (1) comprises at least one base (4) that is disposed on the circuit board (8) and a button top (2) which encompasses the contact element (5) and is movable relative to the circuit board (8) and the base (4). The button top (2) is connected to the base (4) by means of at least one movable membrane (3), the base (4) and the membrane (3) being made of an insulating elastic material. According to the invention, the button additionally comprises at least one soldering leg (6), of which the first end is positively inserted into the base (4) while the second end, the soldering zone (28), is used for fastening the button (1) to the circuit board (8).

Disclosed is a switch (1), especially for use in the interior of a vehicle, which is to be embedded at least in part in or on a support (4) that is covered, at least in the area of the switch, with a preferably flexible surface material (3) on the surface thereof (1). Said switch (1) is disposed in an opening (6) of the surface material (3) while comprising a first zone located substantially in the support (4) and a second push button (2) used for triggering a function. The push button (2) is embodied so as to cover at least some areas of the opening (6) in the surface material (3) and be non-positively and/or positively connected thereto. Also disclosed are a method for assembling such a switch (1) as well as uses thereof as a window control and similar.
