Could someone tell me where I can find the Avionics master switch in the 737-800 in FSX?

For whatever reason you'll find that a few of the default birds were not completely fitted out before they left the ACES factory, and one of these was the 737.The simple solution to their failure to fit an Avionics Master switch is to assign a key press to this action in the Settings/Controls/Buttons/Keys/Radios dialogue.You'll find that assigning a key press to an action will fix a lot of these oversights in the default birds.

Thank you very much!
