Pollak 21-400 Precision Ball Switch – Normally Open (N.O.) – Fits Ford E2EB-14A464-AB

OEM-Grade Sensing for Ford and Heavy-Duty Systems

The Pollak 21-400 Precision Ball Switch is a premium, vehicle-side sensor designed for exact-fit replacement in Ford-based systems and custom industrial applications. Engineered to interface seamlessly with the Ford E2EB-14A464-AB connector, this switch provides a reliable, weather-tight electrical connection that stands up to the most demanding environments.

Precision Snap-Action Performance This Single Pole, Single Throw (SPST) switch operates in a Normally Open (N.O.) configuration, meaning the circuit is "Off" until the ball is mechanically depressed. Whether used for backup light activation, neutral safety sensing, or gear position indication, the 21-400 offers a consistent, precision-engineered response that ensures your vehicle's safety and functional systems communicate without delay.

Built for Extreme Conditions Located typically in the undercarriage or near the transmission, ball switches are subject to high vibration, mud, and road salt. The Pollak 21-400 features sealed terminals and a heavy-duty zinc-plated metal housing to prevent moisture intrusion and corrosion. Its robust internal spring and precision-ground ball are designed for a high cycle life, reducing maintenance intervals and downtime.
