This is a brand new Lucas 3-position toggle switch, on-off-on Lucas no. 31743. It is a less common switch, used for directional indicator lamps. It is correct for many, many British cars of the sixties and seventies, including early MGB, Triumph TR4, Spitfire, Mini, Austin, Morris, big Healey, Land Rover, and many others. It is a nicely made part, genuine Lucas, complete in a new Lucas box.
We also sell the more common off-on-on switches under a separate listing.
