RHEOSTAT (P/N 319-50-2) - New Surplus

The 319-50-2 is a cockpit rheostat that controls aircraft lighting brightness by varying circuit resistance. This variable resistor dims instrument-panel and overhead lighting in low-voltage DC systems, allowing pilots to adjust illumination for different flight phases and ambient conditions. Commonly used in Dassault Falcon business jets, the rheostat mounts in the instrument panel and integrates with the aircraft's electrical system.

Installation follows the aircraft maintenance manual and FAA AC 43.13-1B guidance. Verify compatibility with your specific aircraft's Illustrated Parts Catalog before installation.
