Pollak 21-468 Precision Ball Switch – Normally Open (N.O.) – Fits Metri-Pack (MP) 15300027

OEM-Quality Sensing for Modern Commercial Electrical Systems

The Pollak 21-468 Precision Ball Switch is a heavy-duty, Single Pole Single Throw (SPST) Normally Open (N.O.) sensor designed for the next generation of truck and equipment wiring. Engineered to mate perfectly with the Metri-Pack (MP) 15300027 connector, this switch provides a superior, weather-tight seal that is essential for components mounted in high-vibration and high-moisture areas.

Reliable Snap-Action Performance This momentary switch remains in the "Off" position until the ball actuator is depressed, completing the circuit to trigger vital vehicle functions. It is the professional’s choice for automatic backup light activation, neutral safety start sensing, and providing gear-position data to vehicle ECUs or PTO (Power Take-Off) systems.

Built for the Long Haul Featuring Pollak’s signature self-cleaning wiping action contacts, the 21-468 ensures low electrical resistance and long-term reliability. The rugged, zinc-plated metal housing protects the internal mechanisms from road salt, grime, and thermal shock, ensuring consistent actuation across a wide range of operating temperatures.

Key Features:

• Normally Open (N.O.) Function: Circuit closes only when the ball is mechanically depressed.

• Metri-Pack 150.2 Compatibility: Precision fit for connector MP 15300027 for a secure, sealed interface.

• Environmental Sealing: Sealed terminals prevent moisture intrusion and terminal "green rot."

• Corrosion-Resistant Housing: Heavy-duty zinc-plated steel construction for maximum durability.

• Precision Ball Actuator: Designed for smooth mechanical movement and tight switching tolerances.

Common Applications:

• Modern Truck Backup/Reverse Light Activation

• Neutral Safety Start Sensing

• Electronic Control Unit (ECU) Gear Position Input

• PTO (Power Take-Off) Engagement Indicators

• Construction and Agricultural Equipment Safety Interlocks
