Update:
Finished stickering switches. I might take a picture tomorrow but for now I'm going to sleep.
Opening switches was much easier than I thought it would be. Once I got the process down it only took me a few hours to get all 70 switches stickered. I used a tiny flathead screwdriver to get the tabs, and tweezers worked great for handling the stickers.
Next Step: start soldering (diodes, resistors, and LEDs)
