Abstract

An input device including an input circuit with an input connection point for applying an input signal and with an input signal path which leads from the input connection point to an evaluation input and on which a conversion of the input signal into an evaluation signal is effected, an evaluation device which includes the evaluation input and which is designed to recognise an input signal level of the input signal on the basis of the evaluation signal, wherein the evaluation device is further designed to carry out a functionality test of the input device and within the framework of the functionality test by way of providing a test signal to effect a first change of the evaluation signal and to test the functionality of the input device on the basis of the effected first change of the evaluation signal, wherein the input circuit includes a transistor which is connected into the input signal path, and the input circuit is designed to control a control terminal of the transistor on the basis of the test signal, in order to effect the first change of the evaluation signal.
