Embodiment Construction

[0021] figure 1 Shows an exploded view of a manipulation element capable of pressing and turning operations according to the present invention. A circuit carrier 2 is arranged in the housing 1, which can be implemented as a circuit board or a ceramic carrier plate, for example. The circuit carrier 2 carries a plurality of keys that are not shown in the drawings, and the keys can be electrically connected to each other via a switching dome 4 on a dome-type switching mat 3 supported on the circuit carrier 2. Therefore, the keys together with the switching dome 4 constitute electrical switching elements, which can be operated by pressing the switching dome 4 in each case.

[0022] In the embodiment shown here, the pressing operation of the switching dome 5 takes place via the switching tappet 5, which is therefore formed as an operating element for the switching element. The switching tappet 5 is movably installed in a guide sleeve 6 which is molded in one piece onto a plate-shaped...

Abstract

Described is pressure- and rotationally actuated control element for a motor vehicle, in particular a control element on a steering wheel, comprising a roll-type input element that is rotatably mounted on a bearing block and transmits a rotational actuating movement to a code disk which cooperates with a sensor. The bearing block is mounted on the actuation elements of multiple switching elements. At least one of the switching elements is actuated by applying actuation pressure to the input element. The bearing block forms two swivel pins which extend perpendicular to the axis of rotation of the input element and which rest on actuation elements of switching elements. The bearing block has at least one molded-on stop element between the swivel pins, said stop element limiting the actuation path of the input element when actuation pressure is applied. Two pressure-actuated switching functions which cannot be jointly actuated are associated with the pressure- and rotationally actuated control element of the invention.

Description

Technical field [0001] The present invention relates to a pressing and rotating operating element for a motor vehicle, especially a steering wheel operating element, which has a roller-shaped input element rotatably mounted on a bearing seat, wherein the input element transmits the rotating operation On the code disk, the code disk and the sensor work together, wherein the bearing housing is mounted on the operating elements of a plurality of switching elements, and wherein the pressing operation of the input element operates at least one of the switching elements. Background technique [0002] Such operating elements are known from German publication DE 10 2007 038 580 A1. In the operating element described in the document, the bearing seat is supported on two operating elements, which are implemented as a switching dome of a dome-type switching pad. When the middle part of the operating element is pressed, the two switching domes sink, so that the two switching elements belong...
