CONTACT SET,DISTRIBUTOR (P/N h27-528) - New Surplus

The h27-528 is a distributor contact set for aircraft piston-engine magnetos. This assembly interrupts the primary ignition circuit to trigger secondary voltage distribution to spark plugs, controlling spark timing in the engine. Installed inside the magneto distributor, the contact points open and close based on engine rotation, generating the high-voltage pulse needed for combustion.

Gap and dwell settings must be adjusted per engine or magneto manufacturer specifications and FAA-approved maintenance data. Proper contact condition is critical for reliable ignition performance.
