Claim 17:
18. A switching device comprising:
a stationary contact and a movable contact; and
a permanent magnet and a magnetically-operated switch,
wherein the magnetically-operated switch has a first state and a second state and is switchable between the first and second states as a result of a distance of the permanent magnet to the magnetically-operated switch,
wherein the magnetically-operated switch is connected to a signal processing device, the signal processing device being configured to detect a state of the magnetically-operated switch,
wherein the signal processing device comprises a measuring resistor connected in series to the magnetically-operated switch, and
wherein the measuring resistor is directly connected to the magnetically-operated switch.
