RHEOSTAT ASSY. (P/N 484-577) - As Removed

The 484-577 is a rheostat assembly for aircraft cockpit lighting control. This variable resistor dims and brightens instrument panel lights by adjusting electrical current flow through the lighting circuit. The assembly mounts through a standard panel cutout with a rotary control shaft for pilot adjustment.

Wired into the aircraft electrical system per maintenance manual specifications, it provides smooth dimming capability across the full range of cockpit illumination. Follows MIL-PRF-39015 or MIL-PRF-39023 standards depending on aircraft configuration. Verify compatibility with your aircraft's illustrated parts catalog before installation.
