SWITCH, INERTIA (P/N 110apr4y250) - As Removed

The 110apr4y250 is a mechanical inertia switch that triggers when aircraft acceleration or impact shock exceeds a preset G-threshold. This crash-sensing component activates emergency lighting circuits and avionics systems during hard landings or collision events. The switch changes electrical state upon detecting sudden deceleration, enabling automatic emergency response without pilot intervention.

Manufactured to AS9100 aerospace standards for reliability in safety-critical applications. Install in the designated circuit location per aircraft maintenance manual specifications and verify threshold operation before return to service.
