United Motor Products CP-401 Ignition Contact Set Breaker Points

The United Motor Products CP-401 is an ignition contact set designed for distributor-based ignition systems on automotive, marine, industrial, and agricultural engines. This contact breaker (commonly called "points") is a type of electrical switch found in the ignition systems of spark-ignition internal combustion engines, automatically operated by a cam driven by the engine.

Key Features:

• Interrupts current flowing in the primary winding of the ignition coil, causing the magnetic field to collapse and induce high voltage in the secondary winding
• Manufactured by United Motor Products, a company that produces high-quality OEM replacement ignition and engine management products for automotive, marine, industrial and agricultural markets
• Precision-engineered contact points for reliable ignition timing
• Direct replacement for worn or pitted original equipment

The contact-breaker setting is vital to good running and should be checked between major services, with replacement recommended after 6,000 miles or twice a year. Since contact breaker points open and close frequently, they can suffer from mechanical wear and pitting caused by arcing across the contacts. This replacement set restores proper ignition function and engine performance.
