The contact breaker is the electromechanical switch in a traditional distributor that repeatedly makes and breaks the primary circuit of the ignition coil, triggering the high-voltage spark. Worn or pitted points cause incorrect timing, weak sparks, and poor engine performance. Our contact breaker sets are manufactured with durable tungsten contacts and precise pivot mechanisms. They ensure accurate timing and reliable electrical switching, providing the foundational trigger for the ignition spark in vehicles reliant on this time-tested ignition technology.
