IIDX Button Replacements?

[Mr. A]

I'm building a custom-made PC IIDX controller. I need to find some suitable buttons for it that are the same (or similar) dimensions as the arcade controller, and have the same general properties (low-voltage rating, contact then spring return, normally-open connection or having both a normally-open and normally-closed set of contactors.)

I'm gonna try checking digikey, but it might be difficult.

These aren't perfect, but they might be the best compromise right now. (Kinda has a nostalgic feel to it too.)
