Problems solved by technology

In the case of high system stiffness, this displacement is relatively small (eventually only applicable in some cases); thus, the challenge of finding an accurate measurement method for small displacements increases

Embodiment Construction

[0057] exist figure 1 , a first exemplary embodiment of the operating device 10 is shown. The operating device 10 also includes an elastically supported operating element 12 that moves in a direction away from the relative element 14. figure 1 As shown in 16, a driving force acts on the operating element 12, and correspondingly, the driving force is released. exist figure 1 , the elastic support of the operating element 12 is schematically represented by a spring 18 .

[0058] Fixed to the operating element 12 is a special element in which the first carrier 20 and the elastically bendable second carrier 22 are superimposed. The first carrier 20 can be, for example, a circuit board, while the second carrier 22 can be formed as a strip of metal sheet. from figure 1 It can be seen that the two carrier elements 20 , 22 are fastened in the region of their first ends 24 , 26 and abut against the projection 28 of the other plate-shaped operating element 12 . The protrusion ...

Abstract

An operating device for electrical equipment or systems, particularly suitable for vehicle components, provided with at least one elastically mounted operating element (12), an opposing element (14), relative to which said at least one operating The element (12) is movable so as to vary the distance, i.e. as seen in the direction of movement, and at least one capacitor (38) comprising a first carrier (20) with a first capacitor electrode (34) And an elastically bendable second carrier (22) designed as a bending rod has a first end (26) and a second end (32) opposite to the first end, and has a contact with the first capacitor electrode (34) Opposite second capacitor electrode (36). An evaluation unit (42) is connected to the first and second capacitor electrodes (34, 36) for determining the capacitance and / or the capacitance of the at least one capacitor (38) when the at least one operating unit (12) is actuated Variety.

Description

[0001] prior application [0002] This application claims priority from German patent application 10 2013 225 436.9 of December 10, 2013, the content of which is incorporated by reference into the content of this PCT application. technical field [0003] The invention relates to an operating device for an electrical device or an electrical system, said operating system being particularly suitable for vehicle components. Background technique [0004] Various designs of most operating devices with operating elements are known. Especially in the automotive sector, operating concepts have already been established using operating elements in the form of keys. Recently, there has been an increasing demand for key-type operating elements to be designed such that, when actuated, their surface should move, as imperceptibly as possible to the user. Therefore, it is desirable to achieve as small a travel distance as possible and further to allow these to be detected. On the basis o...
