Caps Lock doesn't disable when I reassigne it for something else

I would like to use caps lock as cmd+tab to go the previous application. It works when I reassign it to cmd-tab but caps lock function still remains too. So it changes the app and also turns on the caps lock whenever I use it. Is there a way to disable caps lock function and use it only for cmd-tab?
