A starter circuit for a motor vehicle includes a circuit breaker responsive to a crash senor for disconnecting the starter circuit. A bypass switch is provided, which responds to a control circuit to provide power to the starter circuit following activation of the breaker, if the starter circuit is free of short circuits.

An arrangement for actuating an airbag includes an airbag control unit, an actuating switch, a visual display device and an intermediate electronics unit. The intermediate electronics checks the visual display device and the actuating switch for functionality.

Airbag actuating arrangement

An electric circuit configuration includes an electric circuit, with a printed circuit board provided in a housing. The printed circuit board carries circuit elements and defines a printed circuit board plane. A plug-in connector element is provided at the housing and has a plurality of contact elements disposed in at least one first row. The plug-in connector element has short-circuit interrupters disposed at respective interrupter positions at the rear wall The short-circuit interrupters are configured as electrically non-conductive pins integrally formed with the rear wall and are disposed in a second row. None of the contact elements are, none of the contact elements are disposed in the second row. The second row is disposed beneath the at least one first row and is closer to the printed circuit board plane than the at least one first row. Thus the number of plug contact elements can be increased considerably without increasing the overall height of the control device.
