Unless you have a framework, and can remove the bezel and confirm that they work!
I'm really happy with my new framework's switches, I actually trust them for once! I went to find a thing on how they work to post here:
"(They) saw the mention of the switches and that they are optical somewhere, but can’t remember to quote the source.
As far as I can tell each switch is a U channel with a light emitter on one side, and a detector on the other. The part you move on the bezel just breaks the light beam. This creates a electronic on/off hardware switch.
Using an actual physical switch would tend to be a source of an intermittent connection over time. Hence the use of optical technology. Same thought process for the screen open switch being a Hall Effect sensor, which can work through a cover."
