Patent ID: 8161942

Claim:
An ignition control device comprises: an ignition circuit module and a killing switch control device; said killing switch control device including a killing switch and a timing retard circuit module; said timing retard circuit module including a charge circuit module having capacitors; wherein when the killing switch is activated, the killing switch control device starts to work and the ignition circuit module stops outputting an ignition voltage; wherein when the killing switch is deactivated, the ignition circuit module is still in a no ignition voltage output state until a voltage discharge of the capacitors in the charge circuit module ends; wherein the killing switch control device further comprises a pair of diodes, a silicon controlled rectifier (SCR), a transistor, a pair of capacitors and a quintet of resistors, wherein said charge circuit module comprises the pair of capacitors and a fourth one and a fifth one of the resistor quintet; an anode of a first one of the diode pair is connected to the backend of a charge coil of said ignition circuit module; a cathode of the first diode is connected to the anode of the SCR, an emitter of the transistor, one end of a first one of the resistor quintet and one end of a second one of the resistor quintet, respectively; the other end of the second resistor and one end of a third one of the resistor quintet are connected to a base of the transistor; the other end of the first resistor is connected to the other end of the third resistor; one end of the killing switch is connected to the point where the first resistor is connected to the third resistor and the other end is grounded; one end of the fourth one of the resistor quintet is connected to a gate of the SCR and the other end of the fourth resistor is connected to one end of the fifth one of the resistor quintet; the other end of the fifth resistor is connected to a cathode of a second diode of the diode pair; an anode of the second diode is connected to a collector of the transistor; one end of a first one of the capacitor pair is connected between the fourth resistor and the fifth resistor and the other end of the first capacitor is grounded; one end of a second one of the capacitor pair is connected between the fifth resistor and the second diode and the other end of the second capacitor is grounded.
