What did I just break?
 

Hello all,

I was trying to replace my clutch handle when I heard a snap sound. I looked around and found that I broke off a small plastic nub. I thumbed through the service manual and I think it's part of the 'starter lockout switch'. I can't, however, figure out what it does or if it's important. Is this something that I need to worry about and replace? Or can I just ignore it?
