Abstract

A switching device for a transmission of a motor vehicle includes an unsynchronized claw switching element that has a first switching part and a second switching part which are rotatable relative to each other around an axis of rotation. The first switching part has a first switching gearing and the second switching part has a second switching gearing which are displaceable relative to each other along the axis of rotation between a coupled position and an uncoupled position. Rotation positions in which the first and second switching parts are rotated relative to each other are detectable by a detection device. An electronic computing device moves the first and second switching parts from the uncoupled position into the coupled position depending on detected rotation positions. The detection device has a sensor element and a transmitter element, with transmitter segments, fixedly connected to the second switching part.
