The speed limiting electronic ignition circuit connection has two series-connected, mono-stable toggles of which the first has a specific pulse time, and is triggered by a zero throughput detector monitoring an induced primary voltage in the coupling. The second toggle has its own pulse time and is triggered by the termination of the first toggle pulse. The time span between the two pulses after the zero throughput during a preceding engine speed constitutes the ignition time at the determined, limited speed around which control must take plate. The toggles are of the so-called non-retriggerably type, and the second toggle output is connected to a control for an ignition current adjuster which is maintained conductive by the toggle pulse in the event of excess speed.
