Yep, my mistake. Thanks. I do mean the copper tab with the black wire attached. Guess I'm no auto electrician! :-[
I'm wondering if the connection is wrongly being made by the 'live' tab, because that tab is only held back against the pressure of the button's spring by the white moulding it sits in. My white moulding looks a bit mouldy! :)

It's really daft, to my embarrassment, I'm still struggling with this darned starter button. I have it off the bike, wired and assembled as per Julie's photos.
As soon as I place the live tab into the switch, even though the button spindle goes through the little hole in the tab nicely, the tab is pushed by the button's spring against the R/Y contact. So, the circuit is always complete. I've tested it on my meter and as soon as the button is pressed once, that's it, the tab remains pushed against the contact.
I think the plastic piece that holds the tab is what is intended to hold the tab away from the contact. It must be worn.
Options:
- get a new one. No longer available.
- Try to modify it?
1. I could put insulating tape on the face that is touching the R/Y contact, with hole in it, so the button pin can still go through and complete the circuit on the contact. Perhaps not a long term solution?
2. Glue a spacer on the bottom of the tab, to keep it away from the contact? Would have to be very thin and it might not be possible to get it into the switch, as it's already very tight.
Any suggestions? :)

Hi Martin! You are certainly being tested to the limit there!😡😡. Having done a couple of these fitted new spring and button as well as general cleaning and refurbishment. I’m finding it difficult to visualise what is going on there. I’m quite sure if it’s fitted correctly and the spring is pushing the button out again it should disconnect the circuit. Double check against photos sent with switch gear internals to ensure proper assembly. It can be a little fiddly to put together, but I’m sure you don’t need any glue unless there’s something broken. Sorry! If this isn’t that helpful, but good luck anyway.
