Pollak 21-562 Precision Ball Switch – Normally Open (NO), Sealed Terminals (Fits MP 15300027)

OEM Precision for High-Demand Electrical Systems

The Pollak 21-562 Precision Ball Switch is a heavy-duty sensing solution designed for the rigorous requirements of the transportation and industrial equipment sectors. This Normally Open (NO) switch is engineered to provide immediate electrical engagement upon ball compression, making it a critical component for backup lamps, neutral sensing, and PTO interlock systems.

Sealed for Maximum Protection & Reliability Built to thrive in the harshest under-chassis environments, the 21-562 features sealed terminals and an integrated O-ring seal. This construction provides a watertight and dust-proof barrier, protecting internal electrical contacts from the corrosive effects of road salt, moisture, and grime. It is specifically designed to mate with the Metri-Pack 280 Series (MP 15300027) connector, ensuring a professional, vibration-resistant connection that meets factory standards.

Built to Outlast the Competition Constructed with a rugged, corrosion-resistant body, this switch is designed to operate in extreme temperatures ranging from -40°F to +250°F. With an exceptional mechanical life of 1,000,000 cycles, the 21-562 provides the long-term durability fleet managers and owner-operators need to minimize downtime and maintenance costs.
