I’m about to build my overhead, parts should start arriving in the next couple of weeks. That being said, it’s always good to know what all those switches do!
I came across this site from Captain Chuck Harman, which gives you a image map of the 737 Forward and Aft overhead panel. If you click a section it enlarges. Finally, clicking on a button, switch or gauge will give you it’s purpose and/or explanation!
