Pollak 21-364 Precision Ball Switch – Normally Open (N.O.) – Fits Ford COAF-14A121-A

OEM-Grade Precision for Ford and Custom Applications

The Pollak 21-364 Precision Ball Switch is a specialized, heavy-duty electrical component designed for exact-fit replacement and high-performance custom builds. Engineered to meet the rigorous standards of the automotive industry, this switch is specifically designed to mate with the Ford COAF-14A121-A connector, providing a secure and weather-resistant electrical link.

Reliable Momentary Switching This Single Pole, Single Throw (SPST) switch functions in a Normally Open (N.O.) configuration. The circuit remains open until the precision-ground ball is depressed, at which point it closes to activate your vehicle’s sub-systems. It is most commonly used for backup light activation, neutral safety start sensing, and gear position indication in Ford-equipped vehicles and heavy-duty transmissions.

Sealed for Survival To combat the corrosive effects of road salt, moisture, and transmission fluid, the 21-364 features sealed terminals. This ensures that the electrical connection remains clean and conductive even in the most exposed undercarriage environments. The rugged metal housing and high-impact internal insulators are built to withstand constant vibration and extreme temperature cycles.
