In a control system for a dual-stage airbag firing system, a series circuit of first and second switching elements and a series circuit of third and fourth switching elements are connected in parallel between high and low voltage power lines, the circuit node between the switching elements of each series circuit being connected to a corresponding one of a pair of output terminals. The jaw is adapted to apply, when it is in the immobilization position, a clamping force to the shaft in a clamping direction perpendicular to the vertical direction, so that the shaft is supported on the housing. If a card is lost, stolen or otherwise rendered unusable, a security suspense record is inserted into the database in an account ID filed associated with the affected presentation ID. A spring-biased discharge control assembly and a check valve are mounted to the pan. Respective generally complementary formations on the end of the rotor and on one of the universal-joint parts can fit axially together to rotationally couple the one universal-joint part with the rotor.
