I'm waiting for the caps to finish drying from the cleaning, but I wanted to post some preliminary shots of my mystery board. I got this in yesterday. I was fairly sure I knew the switch, but not 100% until I popped that cap and confirmed it.
Crappy eBay pic of the board:
Now for the guts. Since I could clean the board without soaking it in water, I can get pics.
Obligatory PCB shot:
And the reveal:
I guessed right, Fujitsu Leaf Spring. These happen to be the Clicky Second Gen switches. I'm probably going to try and get a Soarer's mod going on it and then list it since it's too light and way too loud for me. If you like clicky switches, this is crazy clicky, but with a fairly small tactile bump to it toward the bottom of the switch.
