Product Description
The s1904-1 is a variable resistor (rheostat) that controls current flow in low-power aircraft electrical circuits. This Cessna-catalogued component functions as a dimmer switch for instrument panel lighting, allowing pilots to adjust brightness for optimal visibility during day and night operations. The rheostat varies resistance to regulate voltage to panel lights, maintaining visibility without draining battery power excessively.
Installation requires verification that s1904-1 is specified for your aircraft model and serial number per the applicable Illustrated Parts Catalog and maintenance manual.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
