Abstract

A passenger protection device of an automobile is triggered when a testable acceleration switch supplies a switch signal and an electrically controlled switching device is actuated by a control circuit depending on a collision. Actuation of the switching device is prevented on a triggering circuit side by a blocking device so that the passenger protection device is not triggered as a result of faulty control switching during testing of the acceleration switch.
