The invention relates to a circuit for selectively producing switching signals, in particular signals used for locking vehicle doors, a vehicle provided with said circuit, a system and method for protecting areas of risk and a system, components and method for hermetically transferring validated data. For automotive engineering, it is desired that certain switching processes in or outside the vehicle like the opening of a door, the actuation of a start button or the activation of a parking brake be carried out exclusively by a driver. The aim of said invention is to develop the solutions which make it possible to advantageously produce distinctive signals for coordinating a switching process. For this purpose, the inventive method for generating switching signals consists in producing said signals according to the selective activation of a switching device by a user. The inventive circuit is characterised in that the device signal is emitted towards the user and is transmitted by the user during the actuation of the switching device. The switching signal is produced by said device
