Pressure and rotationally-operated operating unit i.e. steering wheel operating unit, for motor vehicle, has switching unit arranged on circuit carrier, such that bearing block and circuit carrier are movable against each other

摘要

The unit has a circuit carrier (2) comprising an optoelectronic sensor, and an input unit (1) rotatably supported on a bearing block (3). The input unit transmits a rotary operation to a code disc (4) that works together with the sensor, where the input unit operates a switching unit. The switching unit is arranged on the circuit carrier, such that the bearing block and the circuit carrier are movable against each other. The switching unit has an aperture, where the code disc extends into the aperture or the aperture projects from a section of the disc.
