Abstract: The invention relates to an operating unit, especially for operating a multimedia system in a motor vehicle, comprising an operating element that can be rotated about an axis (z), that can be moved along said axis of rotation (z) and that can be locked in a position (0, 1) on said axis (z). The operating element can also be moved on an plane (x, y) that is orthogonal relative to said axis (z) in order to control the movement of a cursor that can be shown on a display in any given direction.

Abstract: Electric appliance, in particular in the form of an automotive radio, having a control element (4) for manual control of the electric appliance by a user, and a transmission unit (5) for wireless transmission of data from and/or to the electric appliance, the transmission unit (5) being integrated at least partially spatially into the control element (4).

Abstract: A key unit includes a transmitter for remote actuation of a lock and, in a common housing, a mechanical key for mechanical operation of the lock. The mechanical key is held within a key compartment in the housing and, when a trigger button is depressed, pivots to an outwardly extending working position on a circular bearing portion. The cover of the housing is held to the lower portion at one location by a bayonet connection which enables the cover to be pivoted to a position for access to the battery compartment in which batteries are contained for the transmitter. A lock connection spaced from the bayonet connection couples the cover to the lower housing portion when closed, and a removable locking screw is provided to hold the cover in the closed position.

Abstract: The invention is based on the object of executing the contacting and fastening of a display element, particularly for a LCD (liquid crystal display), with an arranagement that is simple to execute in terms of production engineering. The display element is illuminated from behind by a light box. To this end, a contact element is allocated to every contact of the display element, this contact element being fashioned as a punched sheet metal part and being secured in a contact receptacle of the light box.

Abstract: An electrical suppressor filter is disclosed which has a filter housing, a circuit board arranged within the housing, electrical components electrically connected to the circuit board and power connection plugs extending through the housing wall and electrically connected to the circuit board. The power connection plugs have integral legs extending into the interior of the housing which are both mechanically and electrically connected to the circuit board.

Abstract: Electrical noise filter with a filter housing, with electrical terminals led out at open face ends, in particular flat plugs, litz wires, plug pins, and with electrical components, in particular inductances and capacitances which, embedded in sealing compound, are installed in the filter housing and connected to the terminals. The filter housing is extended so that the terminal elements facing outwardly are disposed within the filter housing and shielded.

Abstract: A radio interference suppression choke with a low leakage field, includes a ring core formed of magnetically soft material, a plurality of windings each formed of a respective continuous wire wound on the core in separate respective series-connected winding sections, the windings having mutually adjacent transition regions, and an insulating cap disposed on the core separating the windings at least at the mutually adjacent transition regions thereof.

Abstract: Subassembly for electrical components with connecting leads, including a cup-shaped metal housing, a metallic cover closing the metal housing and having a perforation formed therein, an insulating material cup being disposed in the metal housing and having an outer cup bottom being turned toward the cover, a chimney-like projection formed inside the bottom of the insulating material cup in alignment with the perforation in the cover, the projection forming a tunnel-like feed through for connecting leads of components extending out of the subassembly, and an electrical circuit plate for carrying components, the plate being pushed onto the projection at perforations formed in the plate.

Abstract: An insertable connection lead-in plug member designed to close an opening while providing an access opening for wire or cable, or for a tang-shaped connector such as a plug. The plug member is externally cylindrical and hollow forming a cylindrical sealing ring which is closed on one axial end face. The external periphery is axially stepped from the one end from a larger to a smaller diameter and is thereafter conically tapered to a second axial end.
