ABSTRACT:
A response step switch for a motor vehicle airbag system has switch contacts driven by a delay sensor dependent on two response cases. Dependent on the position of a status switch, a logic module selects an electronic selection switch for enabling the triggering of the airbag via one of the switch contacts. The electronic selection switch is not driven until one of the response cases occurs, whereby the control energy comes from an energy source that also supplies the ignition energy for triggering.
