If you want to switch user:

/System/Library/CoreServices/Menu\ Extras/User.menu/Contents/Resources/CGSession -switchToUserID UserID

for UserID

id -u userName

For login Window

/System/Library/CoreServices/Menu\ Extras/User.menu/Contents/Resources/CGSession -suspend

You send an «aevtlogo» Apple Event to the loginwindow app. Look at the documentation for NSAppleEvent<Foo> classes.
