PROBLEM TO BE SOLVED: To realize various action modes by means of only one ignition circuit final step by making program control on the final step action by means of the action of an output electric current by which energy is supplied from an energy accumulator without any control or a limited energy quantity is taken out under control from the energy accumulator. SOLUTION: This ignition circuit final step consists of a down converter realized by corresponding logic part 4 and ignition circuit 16. Input terminals 1, 2, 3, are controlled by one or plural microprocessors. By means of correspondingly large electric current flow or voltage pulses, and before an ignition pill 14 becomes ready to start, both electric power switches 9, 10 must be closed. This situation is achieved by supplying a high level signal to the input terminal 1 for the sake of the first electric power switch 10 and a high level signal to the input terminal 2 for the sake of the second electric power switch 9 independently from each other. In this case, two different signals of high level and low level can be supplied to the input terminal 3. |
