Lucas ignition switch as used by many 50s-70s British cars. Also used by kit cars from the same era to present. OFF-ON-START Nothing beats an original manufactures part. This Lucas switch will replace the one on your car that's been cycled thousands of times during your cars life. Note - does not come with keys or (tumbler) lock cylinder - you may not need a new one... You'll either re-use your cars existing lock - easily removes by depressing a spring plunger, or purchase a new lock assembly sold separately.
