Looking for Lucas switch 30825A for my
Canadian model MK3 Commando.
Can anyone help?
What is that switch? Ignition? Have you tried all the usual suspects like Old Britts in the U.S. Or RGM in England?
Got emails out to all of those guys.
Sorry it's the ignition switch.

Master switch (no lock) part-no: 06.6395, £35.95 + VAT (20%)

Neither come with the lock/key.
30825 (06-6625) is the Canadian model ignition switch (for use with the Canadian assimilator) so isn't the same as the standard 06-6395 ignition switch (AN is incorrect to list it as also being '06.6625').
Doh!, yes you're absolutely correct L.A.B, thanks! I misread the initial post.
Mike (off to rtfm)
Your spot on L.A.B, AN's info is incorrect.
Brit Cycle don't have it either.
Forgive my spelling,
Should have read:
You're spot on L.A.B
There's probably a case of the 30825
switches lying around somewhere.
Walridge lists the 39784 switch as a replacement for both 06-6395 and 06-6625.
So does AN, but 39784 can't be a replacement for the Canadian 30825 switch as the internal connections are different.
If NVT could have used one ignition switch for both standard and Canadian Mk3 models then I'm sure they would have done so, and I believe I understand why a switch with different internal connections is necessary for use with the Canadian assimilator.
Either some parts suppliers don't understand this (BritCycle apparently does) or it's simply because the 30825 switch is no longer available.
39784 is the standard pre-Mk3, 4 position switch with the same internals as the standard Mk3 switch, the difference being the Mk3 switches (standard and Canadian) had a flanged 'bezel' that the Mk3 slotted rubber cover clips over whereas the pre-Mk3 switch had a nut or rounded bezel.
One thing to remember is that it's easy to take your old lock set out so you can use your existing keys. In order to keep it stock I replaced a broken ignition switch in my BSA but put my original key & lock set in it...
Nice to have plug-and-play. I'd bet the switch you need exists, but finding it may drive you mad. I gather that your government had enough time on its hands that it ventured into motorcycle design (US agencies are famous for this). I also gather that anyone in authority who knows this old regulation would be happy to see you riding with your headlight on (good practice). Whether it comes on (and loads the battery) when you are in ignition mode or not is pretty petty, especially for a machine that had this unique part and has been out of manufacture for over 42 years.
So, why not simply wire in the commonly available switch and make sure that you switch the headlight on before riding off? Or if some MOT or DMV type has a check list at inspection I'm confident that you could use the commonly available switch with a work around or a relay to make your government happy.
I have the Quartz light on my bike and am trying to run it off the alternator when the 30825 (06-6225) switch is in the ignition position.
When this switch is in the ignition position there would be power to the guages, tail light, pilot light, signals, warning light, horn, neutral light, brake light the headlight flash switch and the coils, all from the battery.
The battery wouldn't feed power to the headlight, the headlight would get it's power from the alternator through the Canadian model assimilator 06-6392 and would be dim or bright depending on how high the engine was revving.
The right handlebar switch would be in main position and the left handlebar switch in the low position.
I don't have the pilot light in my headlamp shell I have the sealed beam Quartz.
Trying to save my battery power as much as possible as I only use the electric start.
I do have the YTX-20CH Yuasa battery, #4 cables and 4 windings and bearings instead of bushings in the stock starter. Have a new NOS solenoid installed also start button contacts are clean and in good shape.
My ignition switch was replaced with the 30552A switch before I bought the bike. Still using it until I get the 30825 and have ordered the Canadian assimilator from Andover.
Cheers and thanks for everyone's input.
The warning light would vary with speed even though one side of it is fed from the batter the other side is through the assimilator.
Sorry, right handlebar switch in head position not main position as stated in a previous post.
Also, wonder what is inside the Canadian model assimilator as it is fully encapsulated?
I'll try taking my old one apart when I get my new one.
Some kind of rectifier and solid state switch/relay?
Hope it is built to handle the load of the quartz sealed beam I have on the bike!
According to the factory manual, with the Canadian model switch at the ignition position and the engine running; "..... the lights are "on" but are receiving direct alternator current only." Which seems to mean AC as it goes on to mention switching over to; "....the main D.C. (battery) lighting circuit..." so perhaps there's no rectifier in the Canadian assimilator.
I have my original 30825A Lucas Canadian switch.
Where are pictures of these Lucas 4 position ignition switches apart for repair?
