Quoted from woody76:digi key - I bought the individual push button switches and replaced the bad ones instead of a entirely new 3 button switch
Grumpy turned me onto these folks. Got tons of cool stuff.
I bought my replacements from Digikey also. Here's what I used:
outside black switches: https://www.digikey.com/product-detail/en/c-k/F2UOA/401-1225-ND/417519
middle red switch: https://www.digikey.com/product-detail/en/c-k/F2UEE/401-1223-ND/417517
They also sell the coloured caps, but you can just pull the old ones off and push them onto the new switches.
