The last break on default is considered by some to be a coding
standard, by which you explicitly say you wanted to leave the default
block empty, and not just simply forgot.
Also, if unadvised people add code at the end of the switch without
realizing the missing break, your default will fall-through.

That last break is actually unnecessary. The breaks are only to keep
it from going to the next case. In some (pretty rare) cases, you may
not even want to do that, e.g.:
switch(a) {
case 0:
// Does this if a == 0
break;
case 1 :
// Does this if a == 1.
case 2 :
// Does this if a == 1 or a == 2.
default :
// Does this if a is anything but 0.
}
