Do yourself a favour and go watch that movie. There is a huge Hollywood sized grain of salt needed any time you deal with: Hacking, Computers, Internet, etc.. but this movie is EXCELLENT at showing 'Red Team' activities, social engineering, physical bypasses, and true historical hacking (debugging an IC to see what it does).
There is great comedy, action, and intrigue in this film and should be in the top 3 of any nerd movie list.
I thought these looked familiar, I have product that uses them, but a version with dual LEDs. The CFFA3000 hard drive / floppy emulator for the Apple ][ used them in a floppy disc control panel.
Where I did my phd, we had nmr spectrometers that had to be shimmed using a console with these exact switches. I loved interacting with that console..: It was at the same futuristic and absurdly old fashioned. Futuretro.
Edit: oh sweet lord they're listed on ebay. Imagine gutting this things' innards and turning it into a usb input device...
At around the same time, 1990 - 1992, a partner and I made a rack mounted utility unit that included a tuner, a metronome, surge protected outlets and rack lights. We used buttons almost identical to these from Digi-Key. Mouser was also a big vendor of ours.
This post makes me think that I could have a blog if I could avoid going straight to the point and I could build a story around my digikey investigations
People with "disabilities" often have to buy off the shelf equipment made for the mass population, and then adapt it for their needs since most products aren't designed with them in mind.
People who are blind don't necessarily lack vision - that's why the bobbled paving slabs at the edge of crossings and train platforms are bright yellow. [1] Admittedly the LED wouldn't do anything a tactile or audible click wouldn't do here, but a blind user most likely would be able to see that an LED was lit somewhere.
aside from it being embossed tape added after market:
blind covers a lot of ground. the ability to discern a red led against a black background when you're a couple feet away is well within the realm of blind
