Does anyone know what's the small white square gadget with two black buttons on the right hand side of the hatch frame in this video on the second 2185 (36:25 minutes)?

enter image description here

I've been looking everywhere but I can't get a clearer image or information about it, and it seems to be next to almost every hatch of the ISS.

I'll try and find a better picture, but it's the light switch.

Labeled GENERAL LIGHTING, buttons ON and OFF

The best picture I could find is cropped from https://www.asc-csa.gc.ca/images/recherche/hi-res/7ca21bfc-2a90-4dd9-9e22-a3b13d323a18.jpg

I could find no documentation about it on NASA websites :( I did find this info in the International Space Station Expedition Crew Training Notebook (personal copy)

    $\begingroup$ Is there a new, separate control for "General Lighting Color" as well? Is the new RGB solid state LED lighting on the ISS ever used to produce colors other than white? remains unanswered. $\endgroup$

    $\begingroup$ I love that NASA feels their best and brightest might need to have it explained to them how a light switch works. 😂 $\endgroup$

    $\begingroup$ Maybe that button needs to be pressed harder than a home light switch, and the italicised "Firmly" was added after the Best and Brightest had to be told "try again but harder this time" $\endgroup$

  • $\begingroup$ Is that a common light switch layout in the US? Or is it something NASA had made for the ISS specifically? $\endgroup$
