An elastic seal element seals a fluid passage between a first component and a second component from the surroundings, the fluid passage passing through the seal element. The seal element has a first bead, which provides a sealing line to sealingly contact the first component around the fluid passage. The seal element further has a second bead, which provides a second sealing line to sealingly contact the second component around the fluid passage. The seal element has a tubular shape, a tubular casing extending between the first bead at the first end of the seal element and the second bead at the second end of the seal element, wherein the tubular casing allows a transversal offset of the second bead relative to the first bead to seal the fluid passage by the seal element even when the second component is offset transversely relative to the first component.

A connection arrangement () for electrically connecting at least one sensor () or actuator to at least one conductor track () on a circuit board () has at least one compression spring () for electrically conductive connection. The compression spring () is arranged between the at least one sensor () or actuator and the circuit board () so as to be under a mechanical preload. The compression spring has a contact end section () of the at least one compression spring () configured to rest against a contact plate () that is electrically conductively connected to the conductor track (). As a result, the connection arrangement () achieves a high level of electrical contact reliability and corrosion-resistance.

A device for acquiring and processing sensor measured values and/or for controlling actuators has a base housing, sensors and/or actuators attached to the base housing, a cover that can be connected to the base housing to cover the sensors and/or actuators, and a circuit board with control electronics. To mount the circuit board easily and effect secure contact of the sensors therewith, the circuit board is securely connected to the inner side of the cover using press-fit connectors, the circuit board has electrically active first contact faces on its side remote from the cover, the sensors and/or actuators have electrically active second contact faces on their sides facing the cover, and the second contact faces of the sensors and/or actuators are connected to the first contact faces via electrically conductive contact springs.
