Sure theres a way to do that, go to system preferences and go to the logitech
control center and for the app switcher button click the assigned action and change it to keystroke, by default the keystroke for all windows in expose is F9. But before you change to keystroke you need to temporarily change the keystroke of all windows to something else because when you try to input the keystroke it will activate expose. So go to the expose prefs pane and change expose to something else. Then go back to the logitech control center and input F9 then change the expose prefs back the way they were.
