IGNITION LOCK c/w KEYS
Ignition lock and key set, Triumph electrical fitment, catalog number 82-6981 (later 54335169).
This is the ignition lock, complete with keys, that Ed's catalog lists under 82-6981 (older books show it as F6981). It shows up across a long run of electrical figures - headlamp and switch panel drawings, the wiring harness and tail lamp figures, and general electrical equipment layouts - which tells you this is the switch that turns the ignition on and off and locks the steering-mounted electrics, not a separate accessory lock.

Because it comes complete with keys, this is meant to go in as a matched set rather than a bare lock body you'd have to key separately. The part has a long production run in the catalog, spanning from the mid-1960s well into the 1980s across multiple electrical figure groups, so it was used widely, but we don't have specifics tying it to one exact model or year here - check your own parts book listing or call us to confirm it matches what's on your bike before you order.
The factory eventually renumbered this part to 54335169, so if you're cross-referencing against a newer parts list and see that number, it's the same physical lock and key set as 82-6981.
