RHEOSTAT (P/N 0413126-9) - New Surplus

The 0413126-9 is a variable resistor (rheostat) for aircraft cockpit lighting control. This panel-mounted component wires in series with instrument and panel light circuits to adjust brightness by varying electrical resistance. Commonly installed in Cessna aircraft lighting systems, it allows pilots to dim or brighten flight deck illumination for different flight phases and ambient conditions.

The rheostat operates as a simple potentiometer, with a rotating shaft controlling resistance levels. Verify compatibility in your aircraft's Illustrated Parts Catalog before installation and follow your maintenance manual for proper wiring and mounting procedures.
