A switch is formed by a branch including a measurement resistance and a selectable one of switching resistances having different nominal values such that a switch position depends on which switching resistance is selected. The measurement resistance is connected through the selected switching resistance to a supply voltage whereby a voltage drop dependent on the switch position is across the measurement resistance. A controller identifies the switch position by comparison of a measured value (U) of the voltage drop with target voltage drops corresponding to switch positions, calculates a voltage drop (Uges) across the branch based on nominal values of the measurement and selected switching resistances and the supply voltage, forms a difference value (U) between a measured value (U) of the supply voltage and the branch voltage drop (Uges), and qualifies the identified switch position as faulty when the difference value (U) exceeds a difference threshold value (U).

Method for detecting a switching position of a switching device

An electric shifting device for a vehicle includes a shift lever, a gate channel, and a detent device. The detent device has a spring-loaded pin and a detent contour cooperating therewith. The detent contour includes first and second paths and a connection path therebetween. The detent contour is movable relative to the channel between a first position in which the first path is aligned with the channel and a second position in which the second path is aligned with the channel. The lever is connected to the pin such that the lever is movable within the channel along the first path when the detent contour is in the first position and within the channel along the second path when the detent contour is in the second position and such that the lever is movable along the connection path between the paths when the detent contour moves between the positions.
