My MT350 electric Start button has fallen out and now missing.

[padg999]

Hi everyone,
Had a bit of a problem today whilst out on the lanes on the 350. During abit of a dodgy boggy section i managed to knock my electric start button out and didn't realise until further up the lane. The orange button is now missing and all that is left is a hole with a small contact inside. If anybody can help with a new start button assembly or even a complete switch assembly it would be greatly appreciated.

Kind Regards
James
