Abstract: An electronic magneto ignition for internal combustion engines has a permanent magnet mounted on the engine fly wheel and rotating therewith. A magnetic field coil has a primary winding and a secondary winding in which ignition current and ignition voltage, respectively, are produced during the passage of the permanent magnet. A switching transistor is connected in parallel with the primary winding and in parallel with a diode poled opposite to the emitter-collector path of the transistor. An electronic control circuit blocks the switching transistor at the desired ignition time so that the primary circuit is interrupted and the high voltage for the combustion of the fuel is produced in the secondary winding. In the electronic control circuit, a parallel circuit consisting of a first control coil, which has a resistor in series therewith, and a thyristor is connected from the base to the emitter of the switching transistor.
