case 'login' : return login(); break;
case 'contact' : return contact(); break;

case 'lang_change' : return lang_change(); break;

function login() {
echo "initializing login procedure";

function contact() {

This should be in your CONTROLLER. for instance:

Code:

...
$segment = $this->uri->segment(2);
switch($segment)
  {
    case 'login':       $str = "initializing login procedure"; break;
    case 'contact':     $str = "initializing contact form"; break;
    case 'products':    $str = "initializing products form"; break;
    case 'lang_change': $str = "initializing language change"; break;
    default:            $str = "Error, Invalid segment: '".$segment."' passed."; break
}
// now pass the var $str to the view for display
...
