ELECTRONIC IGNITION SYSTEM

An ignition system using electronic switching devices to assist or eliminate the mechanical breaker points . There are three basic electronic ignitions: contact controlled (the breaker points are retained but merely serve to trigger a transistor which switches the heavy primary current ), magnetically controlled (transistors are used as the switching device for the primary current and the points are eliminated -- also called "contactless" or "all-electronic"), and capacitor controlled (also called "capacitive-dischargeSystem" and can be either all-electronic or breaker-point controlled).
