Drop-in replacement for oxidized Philips CRT microswitches?
I have owned a few early 2000s Philips/Magnavox/OEM rebrand CRTs that have broken buttons. I tried to source the original part from the service manual of one of them, but it just took me to an old CRT parts website that has been out-of-stock for years. Does anybody who has experience with these Philips CRTs know what would work as a drop-in replacement from AliExpress or any other site? I'd rather not try to repair the original microswitches, as the two videos I've seen show you have to destroy the top 4 caps holding the plate in anyway.

If you have access to a pair of calipers, you can measure the size of the old buttons and look for replacements of a similar size on DigiKey or Mouser. If the buttons are right-angle buttons, these may be suitable replacements:

I had to replace a rusted button on a Samsung CRT TV a couple years ago, the ones I've linked above got the job done, though the caps were a little short, so I had to push the button on the CRT bezel a little harder than the ones that didn't need replacement. I just found out they also make a version of these with longer caps, which definitely would've solved that problem had I known about them back then:

Maybe order a bunch of both of the buttons I've linked and see if they'll fit, you may have to bend the leads slightly to match the footprint of the originals.

I usually just take the switches from other brands of TV chassis. But, you can easily order new ones. Just measure the size and pin spacing of the original switch and you can find replacements at Digikey or Mouser.
