Input device with redundant detection

The invention relates to an input device(1) comprising at least one input face (2), a plurality of detection means (T1, T2, F1, F2), each adapted, independently of each other, either touching the input surface (2) or actuation of the input surface (2 to detect), an evaluation unit (a), which is designed exclusively upon detection by at least two of the detection devices (T1, T2, F1, F2) the input device(1) upon actuation or touch a switch or control function assigned, characterized in that that at least one detection means (F1, F2) is adapted to detect an operation.
