CONTACTOR (P/N a-703g-1) - As Removed

The a-703g-1 is an electromechanical contactor that remotely switches high-current DC loads in aircraft electrical systems. This heavy-duty switch enables engine starter engagement from the flight deck, delivering short-duration, high-amperage power to the starter motor via a single remote command. Built to MIL-PRF-6106 specifications for reliability in demanding aviation environments.

Installation follows the aircraft wiring diagram and approved maintenance documentation. Commonly found in general aviation and business aircraft electrical architectures where remote load control is required.
