An actuation device for mounting on a vehicle part, in particular in the form of a door or a hinged closure element, is provided. The subject actuation device includes: an electrical switch having at least one switching element for triggering a vehicle function; and a housing unit having at least a first and a second housing portion, which at least partly form a housing interior, in which the switching element is arranged, the second housing portion being movable, at least in some regions, relative to the first housing portion from an idle position into an actuation position in order to actuate the switching element. A vehicle and an actuation method are also provided.

A target device for use with a switch device of a proximity switch has a wireless receiver means (6) for detecting and receiving a first pulsating signal (A) with a first carrier frequency (f1) from a nearby transmitter module (5), demodulating (6, 7) the received signal, and if a superimposed digital signal is present, inverting (9, 10, C4, and Q1) the superimposed received digital signal or, if the superimposed digital signal is absent, passing the existing energy through (10). The target device also has a wireless transmitter means (12) for modulating and sending the inverted pulse train if this exists by the second carrier frequency (f2) to the receiver switch unit (13). Additionally, the target comprises functionality to transmit the carrier frequency (f2) continuous and unmodulated where a continuous and unmodulated carrier frequency (f1) is present. However, upon existence of the pulsating signal only one of the receiver (6) and the transmitter (12) receives or transmits a signal at a given time.

An operator control system includes switches, RFID transponders, and a RFID reader. Each switch has a cap support and a switch cap. The switch caps are respectively interchangeably attachable to the cap supports. The RFID transponders are respectively attached to the switch caps. Each RFID transponder stores a respective piece of information identifying a respective control function so that the switch cap to which the RFID transponder is attached is associated with the respective control function. The RFID reader is arranged on at least one of the switches for reading the piece of information of at least one of the RFID transponders.

A system may include a transmitter and receiver. The system may include an electromagnetic transmission line sensor configured as a passive sensor, configured to determine at least one of a presence of one or more objects or one or more additional sensing parameters, wherein the electromagnetic transmission line sensor is configured as a continuous sensor, wherein the electromagnetic transmission line sensor includes a first port; a second port, wherein one of the first port or the second port comprises the transmitter and another of the first port or the second port comprises the receiver; and a length of waveguide suitable for transmitting an electromagnetic wave, wherein the length of waveguide is configured to couple to auxiliary sensors, wherein the transmitter transmits a packet comprising the electromagnetic wave through the length of waveguide to the receiver, wherein the one or more processing elements of the receiver interprets the packet.
