Pollak 21-361 Precision Ball Switch – Normally Open (N.O.) – Sealed Terminals (Fits PE 2984092)

Maximum Protection in High-Exposure Environments

The Pollak 21-363 is a heavy-duty, Single Pole Single Throw (SPST) Normally Open (N.O.) ball switch engineered for precision performance. Unlike standard switches, the 21-363 is designed with sealed terminals that interface perfectly with the Packard (PE) 2984092 connector. This configuration provides a weather-tight seal that protects your electrical contacts from pressure washing, submersion, and corrosive road chemicals.

Precision Activation for Safety and Function

This momentary switch completes the circuit only when the precision-ground ball is depressed. It is widely used in the trucking and heavy equipment industries as a reliable trigger for backup lights, neutral safety start circuits, and transmission gear position sensing. The internal mechanism is designed for a crisp, consistent snap-action, ensuring a clear signal every time.

OEM Quality Construction

Built to meet or exceed original equipment standards, the 21-363 features a rugged metal housing and high-grade internal components. Whether you are maintaining a fleet of class-8 trucks or servicing industrial machinery, this switch provides the durability needed to minimize downtime and prevent electrical failures.

Common Applications:

• Reverse/Backup Light Activation

• Neutral Safety Start Sensing

• Transmission Position Indicators

• PTO (Power Take-Off) Sensing

• Industrial Limit Switching
