Abstract: In one aspect, an actuating drive for an electrical assembly of a motor vehicle includes a drive train which includes a drive transmission, with the drive transmission having at least one rotatably mounted, first transmission element. The actuating drive also includes a locking unit for locking the drive train, which includes a self-locking locking transmission that has at least one rotatably mounted, second transmission element that is mechanically operatively connected to the first transmission element of the drive transmission. The first transmission element of the drive transmission and the second transmission element of the locking transmission (are mounted rotatably about a common axis of rotation. Furthermore, the first transmission element has a first toothing and the second transmission element has a second toothing which differs from the first toothing.

Abstract: In one aspect, an actuating drive for an electrical assembly of a motor vehicle includes a drive train, which includes a drive transmission and a drive motor for driving the drive transmission. The actuating drive also includes having a locking unit for locking the drive train, which includes a self-locking locking transmission that is operatively connected to the drive transmission, and a locking motor for driving the locking transmission. The actuating drive further includes a control unit for controlling the drive motor and the locking motor. The control unit is designed such that the drive motor and the locking motor can be operated, in particular in a starting operation, asynchronously and/or with a time delay relative to one another.

Abstract: In the case of a multifunctional switch (11) with a panel (14), of injection-moulded ceramic for example, coaxially surrounded by a frame (18), the panel (14) and the frame (18) are produced as separate components, which however are connected to one another in a material-bonding and/or form-fitting manner to form one part by means of an annular light guide (20) that particularly radiates axially parallel and is created by material being injected, introduced by flooding or poured into a gap (17) located between them or is adhesively cemented therein.

Abstract: A handle with haptically high-quality surfaces has decorative and functional symbols above, in or beneath a disc, with a corona-like emission being brought about by the end region of a light-conducting hollow cylinder along the peripheral region of said disc, continuously or intermittently circumferentially, which hollow cylinder is fed from a lighting distribution board parallel to the disc. At the same time, the hollow cylinder radiates centripetally into the peripheral region in so far as it comprises light-conducting material. Apertures representing symbols in the disc can contain fibre optic conductors, which are likewise connected to the lighting distribution board.
