Abstract
A revolution threshold regulator and/or toggle switch has a first and a second fixed phase source of alternating current having a frequency proportional to the revolution speed of a rotor of an internal combustion engine. A trigger device scans the alternating currents to emit a control signal at a revolution threshold above or below a preset revolution threshold. The trigger device has a timer module which cooperates with one of the alternating current sources through a trigger charge element which can be discharged via at least one discharge path to create a control signal. The trigger charge element, as it discharges, sends a control current through a series Zener diode in a blocking direction to the control signal output.
