Got a new calculator, what switches?

Bought this for a wallet busting $3.00 at goodwill. Definitely linear. The outer spring is responsible for the the switch return. With the keycap off I have to manually pull up on the slider to get it to return. The action isn't too smooth, but not gritty. Feels heavier than a mx black but haven't taken any measurements.

Looks suspiciously ALPSish. See if the PCB has any identifiable markings, and desolder a switch for disassembly :D

Indeed, the top of the switch case is very much like T-mount Alps.

Yeah the slider also kinda looks like T-mount. Hard to tell from that PIC. Here's one from my M0110:

Jup, looks very much like an earlier version of the Alps SKCC (Alps vintage tee-mount) switches.

I will do this. It might be a while though. I'm going on vacation tomorrow through the 26'th.
