Which type of ignition system has replaced the breaker points ignition system?

The solid state ignition system has effectively replaced the traditional breaker points ignition system by introducing electronic components that enhance reliability and performance. Unlike breaker points, which rely on mechanical movement to open and close the circuit of the ignition coil, solid state systems utilize semiconductors to control the timing and firing of the spark. This change results in more precise ignition timing, improved energy output, and reduced wear and maintenance needs since there are fewer mechanical parts subject to friction and failure.

In solid state ignition, the elimination of moving parts means that the system can operate at higher RPMs without the mechanical limitations the older systems faced. Additionally, solid state systems can be designed to better withstand temperature variations and vibration, which are common in small engines, thereby extending their operational lifespan. This advancement has made solid state ignition systems the standard in modern engine designs, leading to improved engine efficiency and performance.
