SWITCH, FLOAT (P/N 3515000-165) - Serviceable, Overhauled

The 3515000-165 is a float-actuated level switch for aircraft fuel tanks and reservoirs. As the fuel level drops, the internal float mechanism triggers an electrical contact, sending a discrete on/off signal to cockpit annunciators and control systems. This switch provides low-level fuel warning capability, alerting pilots to insufficient fuel reserves during flight operations.

Installation follows aircraft maintenance manual procedures and requires verification against the Illustrated Parts Catalog for compatibility with your specific airframe. Typical aircraft installations include general aviation and corporate aircraft fuel system monitoring.
