An arrangement for monitoring the switching state of a switch has a monitoring circuit that monitors a circuit containing a first switch. The monitoring circuit has RFID electronics and a second switch. An outlet of the RFID electronics is connected in series with an RFID antenna, and the second switch is connected to an input of the RFID electronics, such that the second switch opens or closes the monitoring circuit dependent on the switching state thereof. The first and second switches are coupled to each other so that the switching state of the second switch is controlled as a function of the switching state of the first switch, so the switching state of the second switch represents the switching state of the first switch. An RFID reading device is within range of the RFID antenna, and feeds a query signal via the RFID antenna into the monitoring circuit to determine the representative switching state of the first switch via the switching state of the second switch.
