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.

Hi, thanks for your reply. Yes, the spring is pushing the button back out.
It is difficult to explain in writing: the spindle in the button goes through a hole in the 'live' tab. The spring around that spindle pushes against the live tab. By 'live tab' I mean the right angled piece of copper that has the black wire soldered to the top and a hole for the button pin to pass through. The action of the spring against the live tab is enough to force that tab against the RY contact, so it is closing the circuit, whether the button is pushed or not. I think the white nylon / plastic piece that screws the live tab to the switchgear housing, should hold the live tab firmly, so it doesn't move. Not the case on mine.

Thanks. Unfortunately, the K6 also has the lights switch on this RHS (the P/H slider).

I owe you a pint! Switch ordered.
I hate to concede defeat, but 2 1/2 days on that bl***y switch is enough. Long lead time for delivery, but I have a back wheel to build anyway.
Thank you again Ted and thank you to everyone who has pitched in.

Oddjob:
That's a copy switch Martin, in case you didn't know.
How can you tell? Very easily. The original switch doesn't have the dot coloured in red next to the P and H, the copy does. I don't think the quality matches the original Honda switches but it does the job and looks the part. If you want the throttle control system just drill the small lug on the bottom between the cable outlets 4mm, tap out to 5mm and fit the sleeper ramp inside the switch and the thumb screw and spring on the outside, I have them all NOS if you're interested. Comes in very handy on the motorway, just wind it in till the throttle sticks and you can avoid all that wrist stress of keeping it open, you can still operate the throttle if needed, it's just a bit heavy until you wind it back out again.
I've just done my switch halves again last night at 3am, filling in all those little letters etc. I often wondered why Honda left some unpainted but filled in the others, I did them all on my 2 R/H switches, even went further and did the run and it's corresponding dot in green as I think that's appropriate, green for go and red for stop seems to make sense to me. Just need to clean up the overpainting and they are ready to reassemble.
