Locating Lucas Switch NOS

Hey Everyone, hope you're well. I've been away a bit as my bike is off in very capable hands for a rebuild that I'm really psyched about. It should be home in the near future. In the mean time, I'm hoping to get help with sourcing some Lucas Switches and figuring out the part numbers so I can search.

Does anyone have a good idea where I could locate some new old stock (NOS) Lucas switches for a 1973 Commando 850? And what would be the correct part numbers for both left and right?

I have what I *think* are the original switches, but as the rest of the bike is restored the worn ones may look uglier. I considered upgrading to reliable Japanese switches but I'd rather keep the original quirky look of the Lucas Controls.

Here are some photos of what I have now. Thanks!

If you already have these, just rebuild them. Nothing really wears. Clean the contacts and grease the moving parts.

The cables can be made to look new in most cases. The buttons, levers and springs are all available as kits of new parts and they are identical to the originals. The housings can be polished to look better than new.

Don't loose the TINY springs and balls when you take the switch gear apart.
The equally TINY screws that secure as well. Those screws don't get much purchase
in the housings so be very careful when running them down.

Dismantle inside a clear plastic bag, any flying springs or balls will hopefully be contained inside the bag.

I tried that but passed out before I could get the job done.....

It is possible to purchase the correct wiring, and also a ‘repair’ kit of ball, springs and paddles Lucas marked.

Your bare shells can then be brought back to a better standard by polishing - please don’t chrome them.

I just did a quick evilbay search and here’s what I’m talking about, just check what switchgear you have first.

Would be Lucas kit WW10421 (but no red button):

Go to eurojamb.com. Joe has what you need but wear visors when visiting this site.

Welcome back! If they are working ok I’d just give them a polish and clean the paddles and buttons with an old toothbrush. To clean the grey sleeving I use “Cream cleaner” on a damp cloth. Not sure what that would be called in the U.S., but it’s a chalky white fluid with possibly a bit of ammonia in it Used in the kitchen etc. Solvol Autosol also works.
