The invention relates to an input device () for safety-relevant functions of a motor vehicle, having a switch contact () with a first connection () and a mating contact () with a second connection (). A first resistor () is connected between a voltage supply connection () and one connection () of the switch element () and a second voltage supply connection () is connected to the other connection () of the switch element (). A measuring node (), via which an actuation-dependent voltage can be captured, is provided between the first resistor () and the associated connection (). The problem addressed by the invention is that of developing input devices of the type in question such that they can be used for safety-relevant applications in the motor vehicle. This problem is solved by the switch contact () having a third connection () at which a second resistor (), which is connected to the second connection () of the switch element (), is provided.

The invention relates to a system for the monitored signalling of a vehicle state, in particular for the monitored signalling of an activated, at least partially automated, driving operating state of a motor vehicle and to a method for the automatic monitoring of a vehicle state-signalling device. Specifically, the invention relates not only to the system and to the method but also to a monitoring device for carrying out the method, to a computer program which is configured to execute the method and to a vehicle state-signalling device and to a vehicle, in particular to a motor vehicle, equipped with the system. In the method, a first control signal, which is configured to change an assigned signal encoder of the vehicle state-signalling device into a deactivated state, is transferred to the vehicle state-signalling device. Testing of a current actual operating state of the signal encoder is then carried out. If the testing reveals that the signal encoder is in an activated operating state despite the transferred control signal, at least one predetermined fault remedying action which is assigned to this test result is triggered.
