Apparatus in magneto ignition systems for providing time separated sequences for charging and triggering in cophased charging and triggering voltage sequences, including inhibition of the ignition sequence in such apparatus. The ignition system includes a triac as a control member, a rectifier being included in the control circuit of the triac, the rectifier having its polarity disposed such that time-separated charging and triggering intervals are obtained. Across the rectifier there is connected a short-circulating circuit or providing triggering control voltages to the triac, even during the charging interval, thus preventing charging, which results in inhibition of the ignition sequence.
