Abstract:
1. A multifunctional display and operating device in a motor vehicle, comprising: a display field adapted to display information; and operating elements adapted to select functions arranged adjacent to the display field; wherein the operating elements are arranged as keys which are each pivotable about a rotational axis extending one of (a) in and (b) at an end region of the keys parallel to a surface of the display field; wherein the keys include a push rod projecting from a side located opposite an operating surface, one end of the push rod adapted to interact with a switching element of a switch mat during operation of the operating element, the push rod arranged at an opposite end region of the key; and wherein the switching element is configured to exert a force, during operation of the key, counteracting operation on the key via the push rod, the force first increasing with increasing excursion from an unoperated setting, reaching a local maximum at a haptic point, and decreasing in response to a further increasing excursion, until a local minimum is reached at a stop point corresponding to an excursion at which a switching process of the switching element is triggered.
