Kill Switch

[Nourish]

I was quite chuffed to get one of these kill switches that screws to the back of the handlebar lever . But as you can see it's empty - Would anyone have any pictures of what should go in there - does it just earth through the handle bars via the steering bearings? Cheers

Pushing the button makes the earth circuit and kills the mag/engine.
I had the same issue as you, and I had to use the guts from a repro "clamp on the handlebars" kill switch. They were identical inside although the body is different.

It should have a round plastic bit with a central connection which accepts the wire from the magneto.

Here’s a new one, has screws in the packet

This has come up on Ebay - is this the same as the cheapo copies? - it looks like a brass contact in the middle with a spring or copper surround to it - how does the wire connect?

[Nourish]

Ah thank you - so a screw passes up through the bottom to clamp the wire? and the surrounding copper piece - what does that do?
Rex - are the repo's the same?

[CheeserBeezer]

That's what the button makes contact with when you press it, so the wire from mag gets earthed and kills the primary side of the mag.
