If I'm thinking correctly, I think there should be a pin/dowel in the bottom half of the switch case that fits in a hole in the handlebar. It depends which type of switch gear you have though.
Look inside the switch and tell me how many wires go to the starter button, there are two type of switch which work differently
Two wires, black and red/yellow.All the wiring diagrams show an earth which is what I confused by.
I think your right, Ill see if I can find another switch. Got a few in the junk pileIf not Ill improvise.
