PURPOSE:To emit a powerful ignition spark as well as to keep off a wasteful consumption of battery power, by intalling a thyristor trigger circuit having a semiconductor switching element to be controlled by a signal out of an ignition signal waveform composite circuit. CONSTITUTION:A terminal 16 is of input terminal of an ignition signal out of a semiconductor ignition signal generating circuit. The cathod of a diode D1 is connected to the terminal 16, while the anode is connected to a transistor 22 via a resistor R1. A collector of the transistor 22 is connected to the anode of a diode D2 via a resistor R4, while the cathode is connected to a gate of a thyristor 24 and grounded via a resistor R5. Thus, a powerful ignition spark becomes generable and, what is more, a wasteful consumption of battery power comes to be avoidable. |
