Brake Switch – Assembly Sealed – CR138890

This sealed brake switch assembly is built for Crown lift trucks, measuring 3.05 by 1 by 0.1 inches. As a sealed unit, it's constructed to keep out moisture and contamination, an important feature for a switch mounted near brake components where it may be exposed to hydraulic fluid, dust, or washdown.

A brake switch signals the truck's control system when the brake is applied, commonly used to trigger brake lights or to interrupt drive circuits during braking. Over time, even a sealed switch can develop internal contact wear or a compromised seal that lets in moisture, leading to intermittent signal loss or a switch that fails to register brake application consistently. Because this switch ties into a safety-related circuit, reliable operation matters for both brake light function and any drive-interlock behavior tied to braking.

Sized for Crown equipment, this sealed brake switch assembly is a direct replacement part for shops addressing brake signal faults on Crown lift trucks.
