Pollak 21-482 Precision Ball Switch – Normally Closed (NC), Sealed Terminals (Fits PE 12010973)

Precision Engineering for Heavy-Duty Performance The Pollak 21-482 Precision Ball Switch is a rugged, high-performance solution designed for reliable switching in demanding automotive and industrial environments. Unlike standard switches, this model features a Normally Closed (NC) circuit, meaning the circuit remains closed until the ball plunger is depressed.

Weatherproof and Durable Construction Built to handle the toughest road conditions, the 21-482 comes with sealed terminals that offer superior protection against moisture, dust, and road grime. It is specifically designed to mate with the Packard Weather Pack (PE 12010973) connector, ensuring a secure, watertight electrical connection. Whether it's for neutral sensing, back-up lamps, or PTO interlocks, this switch is engineered for longevity.

Reliable in Extreme Environments With a wide operating temperature range from -40°F to +250°F, this switch performs consistently in engine compartments and under-chassis applications. Its high cycle life (up to 1,000,000 mechanical cycles) ensures that your equipment stays on the road longer with fewer maintenance intervals.
