OR simply desolder the microswitch on the board, put in a new one that is close to the same, solder back on and away you go
I've modified several Tadao Yakuza boards in the past to allow me to use microswitches instead of the optical ones that come with the board.. It's a VERY simple procedure really.. And saying to just scrap a board due to a broken microswitch is horrible in my opinion..
If you DO intend on scrapping it.. Please send it to me instead and I can use it
