Electronic switching circuit

Claim 1

A MULTIPLE TRANSISTOR SWITCHING CIRCUIT FOR USE IN A SPARK-IGNITION SYSTEM WHICH INCLUDES AN IGNITION COIL, SWITCHING MEAN, AND ENERGIZING CURRENT SUPPLY MEANS, SAID MULTIPLE TRANSISTOR SWITCHING CIRCUIT INCLUDING IN COMBINATION, FIRST AND SECOND TRANSISTOR MEANS, EACH HAVING EMITTER, BASE AND COLLECTOR PORTIONS, OUTPUT CIRCUIT MEEANS FORM ING A FIRST CURRENT PATH INCLUDING SAID EMITTER AND COLLECTOR PORTIONS OF SAID TRANSISTOR MEANS FOR CONNECTING THE ENERGIZING CURRENT SUPPLY MEANS TO THE IGNITION COIL, FIRST AND SECOND RESISITORS CONNECTED RESPECTIVELY BETWEEN SAID EMITTER AND BASE PORTIONS OF SAID FIRST AND SECOND TRANISTOR MEANS, MEANS FORMING A SECOND CURRENTT PATH ADAPTED FOR CONNECTIONN TO THE ENERGIZING CURRENT SUPPLY MEANS FOR FFORWARD BIASING SAID FIRST AND SECOND TRANNSISTOR MEANS, SAID SECOND BRANCH PORTION INCLUDING SAID EMITTER BRANCH PORTIONS THEREIN, SAID FIRST BRANCH PORTION INCCLUDING SAID FIRT RESISTOR AND A THIRDD RESISTOR IN SERIES THEREWITH, SAID SECOND BRANCH PORTION INCLUDING SAID EMITTER AND COLLECTOR PORTIONS OF SAID FIRST TRANSISTOR MEANS AND SAID SECOND RESISTOR ANDN FURTHER INCLUDING A FIRST ZENER DIODE AND A FOURTH RESISTOR AND FURTHER INCLUDING A FIRST ZENER ZENER DIODE CONNECTED ACROSS SAID COLLEECTOR AND BASE PORTIONS OF SAID SIECOND TRANSISTOR MEANS, AND MEANS COUPLING THE SWITCHING MEANS TO SAID SECOND CURRENT PATH CAUSING INTERMITTENT ENERGIZATION OF SAID SECOND CURRENT PATH TO THEREBY PRODUCE INTERMITTENT FORWARD BIASING OF SAID FIRST AND SECOND TRANSISTOR MEANS AND INTERMITTENT ENERGIZATION OF SAID FIRST CURRENT PATH, SAID FIRST AND SECOND ZENER DIODES BEING POLED TO PREVENT CONDUCCTION FROM SAID SECOND CCUURRENT PATH TO SAID FIRST CURRENT PATH.
