I remember seeing a post about taking the ignition / headlight switch apart, bits going everywhere, and it being put in a box for later and replaced. So anyway, I'm on a budget / hate throwing anything away / a sucker for punishment (delete as appropriate) so I decided to pull apart my headlight switch as it was only partially working.

I'll add some pics after dinner, but the short version is that it is pretty simple to disassemble, clean, and reassemble without losing any parts as long as care is taken, and ideally hands that aren't too large. 

Important part is being slow to take it apart, patient to put it back together, and own a small flat head screwdriver and some equally small pliers

I've done a few and it's not that difficult. Only those wee sprung terminals can be a nuisance. Otherwise it's all pretty straightforward. Good clean up and good as new. The PRS8 switch on the other hand is much more meddlesome. Good on you Neil. Best way to understand something is to take it apart, as long as you can can reassemble it, of course wow

This is correct alignment, it is possible to align it incorrectly!

I think it's been covered before - but well done anyway. I seem to remember that it was recommended to dismantle the switch while it was inside a large plastic bag to retain wayward springs.

🤣 

That's just a pile of m4 nuts I've been using for internal rust and grime removal on things like the fork legs and petrol tank
