Friend found a vintage SR2000 in some shop and we are trying to identify what switches it use.
Upon researching I traced back to it's OEM product which is a Nakajima ax-240
It looks similar to some Mitsumi hybrid switches upon inspection and research but there's not further information online that can confirm this.
Here is an image attached.

Very similar have been spotted before in a typewriter but nothing conclusive. They are thought to be Mitsumi though.

If you can, definitely crack it open and see if there's any branding or part numbers.
