| 摘要 |
The invention relates to an operating element for technical systems in vehicles, comprising four separately operable key elements (8, 9, 10, 11) and a turnably supported roller (2), which can be moved by compression perpendicular to its axis of rotation (18), whereby the four key elements (8, 9, 10, 11) are placed crosswise and the turnably supported roller (2) is in the middle between the crosswise-placed key elements (8, 9, 10, 11), whereby the axis of rotation (18) runs parallel to the plane of the key elements (8, 9, 10, 11), and the movability of the roller (2) is perpendicular to this plane.
