Abstract
An electronic ignition system of the capacitor-discharge type for an internal combustion engine includes a magneto generator having substantially a single generating coil with no center tap, and includes a change-over circuit which changes over the supply of power generated from the generating coil from the capacitor to an auxiliary unit when the capacitor is charged to a given voltage by the half-waves of one polarity of the alternating electromotive force generated in the generating coil. The opposite-polarity half-waves of the alternating electromotive force are supplied to the auxiliary unit even while the capacitor is being charged.
