I see this device in many places in International Space Station; what is it called and what does it do?
A clear close up of one is at https://www.watchuseek.com/threads/small-white-timing-clock-inside-the-iss.125971/ - they are Pyrex Professional brand kitchen timers.
If the link above does not work, I've found this:
One can see the 10 buttons. It does seem that NASA did not get ones prominently marked "Pyrex Professional".
You might be amazed how many kitchen timers can be found in labs around the world.
The Smithsonian Air and Space Museum has one that was used on STS-95 on display. The description states it was used by John Glenn on STS-95 in 1998, and the country of origin is "United States". So it's possible these were custom designed for the space program and either also sold on the civilian market, or copied. The first photo below is the actual timer used by John Glenn, and the second states it is a "replica" of the ISS version. The "Time Check" trademark logo would indicate that it was made by an outside entity.
