Abstract: An actuation plate with symbol illumination for a sensor switch button includes a support plate with a first surface on which a metal layer is applied. A luminous layer of light-scattering material is applied on the support plate and at least partially on the metal layer. An opening is provided in the support plate through which a first end of a light guide projects, and a second end of the light guide is optically connected to a light source. The luminous layer is adjacent to the first end of the light guide.

Abstract: A device for electrically interconnecting two relatively rotating members, such as a vehicle steering wheel and steering column assembly, has a stationary housing portion carried with the steering column assembly and a moving housing portion carried with the steering wheel. A plurality of flexible, electrically conductive wires are spirally wound around the device between the two housing portions. Each conductive wire is guided in a direction-reversing loop formed therein. Each conductive wire is affixed at each of its two respective ends at electrical terminals.

Abstract: A printed circuit board for population with surface-mounted devices is provided simultaneously with a lead frame, which has a three-dimensional shape and which is surrounded by a plastic.

Abstract: A steering column switch, especially for a motor vehicle, contains a switch lever, which is activated transversely and which has a magnetic signal transmitter, to which several stationary magnetic-field sensors coupled to an evaluation unit are allocated for determining the switch positions of the switch lever. The switch lever supports a rotary switch and the signal transmitter and also the magnetic-field sensors are used for determining the switch positions of the rotary switch.

Abstract: An electrical connecting device, in particular for arrangement between steering wheel and steering column switch module of a motor vehicle, comprises a stationary housing portion and a housing portion rotatable relative thereto, which in each case carry a terminal unit and surround at least one spirally wound flexible electrical wire which is in each case connected terminally to the terminal units and guided in a direction-changing loop within the housing. At least one additional, spirally wound, flexible electrical wire is provided, which is connected to the terminal units and which is guided in a direction-reversing loop within the housing.
