Need help on identifying unknown heavy switch from a Ham radio desk microphone

So I got a ham radio set from yahoo auction a couple of months ago, and it included an Adonis desk top microphone to be used on ham radios. Interestingly, it has dedicated switches that seemed like SKCC at first (this was the same time when I got a mahjong module with SKCC creams, so I thought that these switches would be used commonly besides keyboards). But the switches are heavier than others, like really heavy for keyboard switches. It has a tee mount and seemed like the caps are compatible with SKCC creams.

The caps from this switch does work on SKCC creams, but the caps from the creams does not work on this switch. The keycaps from the unknown switch is too lose for SKCC tall creams, so the switch mount is bigger than the skcc creams, but smaller than the tall creams.

I can't find any info on these on the wiki or in the forums, but the fact that these are dedicated switches seems interesting. Here are pics of the microphone itself.

My best guess from your pics is a custom weighted variant of the Mitsumi Type 1 or Type 2 standard mechanical switches based on this post, viewtopic.php?f=2&t=19555&start=, & the wiki for them, wiki/Mitsumi_standard_mechanical. I could be wrong, but they sure seem to fit the bill with the mentioned caps issues between these & genuine ALPS SKCC switches.

It doesn't seem like it, I tried the fitting of the caps from my Mitsumi Type 1 and it doesn't fit on the heavy switch, but it works the other way around. On closer inspection, the keycaps on the heavy switch has a larger hole than the caps from Mitsumi.

The switch top housing isn't symmetrical like the other keyboard switches and there's the piece of stem thing at the bottom of the switch for alignment on the PCB (something like the ones in the cherry type switches, no idea what that part is called). Guess I have to desolder and disassemble the switch to identify it.
