MK 111 Ign. Switch upgrade.

The switch on my T160, which I suspect as the same on the Mk3, lasted for 45 years when I replaced it a few months ago.
So I guess the perhaps first you should identify how long you a planning to live for and base the modification on that.

O.K. I'll just get a new one from Walridge.
I can't plan how long to live with much reliability .
Particularly since I drive a 46 year old motorbike.
