CONTACT BREAKER
A Lucas contact breaker for magneto ignition with automatic advance and retard.
This is a Lucas contact breaker, the part inside a magneto that opens and closes to trigger the spark. It's listed in the catalog under the magneto with automatic advance and retard, so it's built for a magneto ignition setup rather than a coil-and-points arrangement on the timing cover.

The catalog only shows this part turning up once, tied to a single year, so we don't have a lot of history on it beyond that one listing. If you're chasing a magneto rebuild or a points replacement, it's worth confirming this is the right breaker for your specific magneto before you order.
Give us a call if you want to talk through your magneto's setup and make sure this matches what's currently on the bike.
