A plastic film for a multi-modal input device has conductors that link a touch module and an operating element. Such input devices, for example, are in consoles of motor vehicles, dishwashers, washing machines, telephones, or the like. Touch modules and operating element modules are interconnected by the layout of conductors in the form of a geometrically distorted electrical matrix on a single plastic film which forms a carrier for a combined input device. The conductors are electrically insulated from each other, but capacitively coupled to crossover points in the electrical matrix, the crossover points dividing the matrix into at least two areas. Strip conductors extend from the matrix at an edge area of the matrix of the touch module and connected to the operating elements forming a geometrically distorted matrix of conductors on the plastic film.
