Abstract
A safety arrangement for an ignition circuit for an air-bag comprising a series connection between two switches and an ignition squib between a power supply and earth. A potential derived from a predetermined point in the series connection is monitored by a central processing unit and by a comparator which compares the monitored potential with a reference potential. When the monitored potential exceeds predetermined limits, both the central processor unit and the comparator operate to disable the power supply.
