These BB2 deck buttons were made by Esterline Technologies.
The circuit boards/caps/bezels were made by Korry Electronics....they also make aircraft pilot control button panels...lol
In this link to a panel page, you can see the OLED buttons that they use in fighter jets and commercial airliners and built to MIL-STD specs...>>>
