A component assembly for a motor vehicle includes a housing and an actuating element that is rotatable about an axis. The assembly also includes an actuator which is configured to cause rotation of the actuating element. The assembly further includes a rotatable shaft which extends along a shaft axis and is disposed between the actuating element and the actuator and which is coupled to the actuating element and the actuator. The shaft is guided through a first through opening in the housing. A sealing system which seals a first end of the first through opening in relation to a second end, facing away from the first end, of the first through opening against liquid media passing through is provided in a radial direction that is perpendicular to the shaft axis so as to be between the shaft and a first internal wall of the first through opening. The sealing system has a first sealing element having a second through opening through which the shaft is guided. The first sealing element has a radially inward-pointing first internal side as well as a radially outward-pointing first external side. The first sealing element by way of the first internal side in a sealing manner encircles a shaft external side of the shaft. A first material of the first sealing element largely comprises polytetrafluoroethylene (PTFE).

The apparatus simplifies release of the locking connections. The second housing section of the electrical device is designed rotationally asymmetrically in such a way that when rotated about the longitudinal axis, the electrical device at one particular side wall of the second housing section causes the at least one locking connection to open.

Apparatus for attaching an electrical device to a housing

An ignition coil for an internal combustion engine has a rod-shaped magnetic core, which is situated within a secondary coil shell. The annular interspace between the magnetic core and the secondary coil shell is filled with an electrically insulating molded material. To prevent the formation of tears in the molded material during thermo-mechanical loading, or the spread of such tears such that the operativeness of the ignition coil is adversely affected, a separation element is provided, which divides the molded material into at least two mutually separate regions.
