Embodiment Construction

[0014] Pass Figure 2 First of all, the problems on which the present invention is based should be elaborated according to the functional member of the traditional composition shown in the sketch. Figure 2 Illustrated functional member having a bearing member 10, the bearing member having a gap 12. The bearing member 10 is composed of a hard material, that is to say, it does not bend under slight pressure load. The load-bearing member is particularly composed of inelastic plastics.

[0015] On the surface of the bearing member 10 is provided with a film 20, the film covers the notch 12. Within the notch 12, under the film 20 is provided with an electrical switch 30. It includes a mechanically operable switching element 32, the switching element is on the circuit board 34. The switch 30 further has a switch housing 38, guiding the switch pushrod 36 at the switch housing. The switching actuator 36 is mechanically in contact with the switching element 32 on one side and is attached to...

Abstract

The invention relates to a functional component with a key function, which is provided with a hard bearing component with at least one notch; a film covering the notch of the carrier member; and a mechanically actuatable electrical switching element which is arranged below the cutout and which can be actuated by applying a pressure to the membrane in the region above the cutout, an annular or hollow cylindrical body being arranged along the inner edge surface of the cutout and in contact with the membrane.

Description

Technical field [0001] The present invention relates to a functional member having a key function, having: a hard bearing member, the bearing member having at least one notch; a thin film, the film covering the notch of the bearing member; and a mechanically operable electrical switching element disposed under the notch, the switching element may be operated by applying pressure to the film in the area above the notch. Background [0002] This functional member is known from the German publication document DE36 41 003 A1, wherein the film here constitutes an elastic film with an outward convex arch. [0003] For some applications, the use of arched elastic films for desired design and haptic reasons is unacceptable. Thus, for example, in the automotive field particularly desire a flat and highly smooth surface, the surface should nevertheless allow the operation of the mechanical switching element disposed under it. [0004] The proposed film here is usually over-injection molded...
