Control device and an acceleration sensor device

The present invention relates to a control device or an acceleration sensor device. In this case, the control device has an electronic safety switch, the safety switch independently of the processor, to allow the operation of the output stage for driving and controlling an occupant protection means depending on the signal of the acceleration sensor device the processor controls the driving of the output stage in dependence on the signal of the acceleration sensor device. Safety switch is to evaluate the acceleration signal is integrated.
