Vintage Synth Repair

I'm working on a dorked Kawai R100 drum machine and I need to locate some 
replacement switches. See the photo here:

It's the blue one I'm mainly after. I think the black one is a standard Alps 
switch (like you'd find in some PC keyboards from days gone by). The blue 
one that I'm looking for appears to say JAE  and D0 on it. It also looks 
like I could disassemble and clean them, but while I have the beast open I 
thought I would try to source replacements. They are used on the drum 
machine for function selection and they bounce like crazy so it's hard to 
make the intended choice.
