I'm confused. This works for me (mostly) on Windows XP with wxPython
2.8.7.1. I put a 

print event.GetKeyCode() 

in your event handlers (Switch) and they printed the key codes for me. I
use the EVT_KEY_DOWN event in my grid object to catch keypresses and they
work flawlessly. What OS and wxPython version are you using?
