Replacement micro switches for tilt

Hello all,

I have two Roccat KONE XTD Opticals and both have had the exact same failure, the left mouse wheel tilt. I have been trying to find replacement switches but have had no luck and was hoping someone here could point me in the right direction of the model numbers and perhaps even where to pick a few up.

While I know there could be an issue somewhere else on the PCB I'd like to at least grab a few of these switches in hopes of testing. I think everyone can agree paying $3 for a few switches and doing a tear down and some soldering every 4 months is a lot better than shelling out $100-$120 every 4 months to replace the whole mouse when only a single button has failed...repeatedly!
