Your problem is probably ill-defined.
What do you mean by "user switches to a different buffer"?
There's a switch-to-buffer command, that you could advice, but it
probably is not all that you mean.
For example, the user could change the selected window or/and the
selected frame, and thus the current buffer, without switching to a
different buffer in any window.

or post-command-hook. But since those hooks are run for each command,
including each character insertion, they must be very light.
