2015 Clutch Switch

I have an intermittent start problem which I am convinced is the clutch switch playing up. Thought I would clean or replace if poss. Just found out that Mr Triumph does not sell it separately, and is £153 as it is part of the left hand switch gear .
Has anyone managed to find a replacement that I can swap or if you have bypassed it, does it like Suzuki’s and force the bike to use a specific map?
