I believe this question has answers that will work for you. I’ll post summaries here for convenience.

From Ryan McGeary:

The session with Twitter is defined by
a cookie owned by Twitter — something
you do not have control over. You
cannot log them out of Twitter on
their behalf.

If you want someone to be able to use
your “switch twitter account”
functionality, you’ll need to pass
them off to the OAuth handshake again,
but use the /oauth/authorize path
instead of the /oauth/authenticate
path. This will allow the user to
switch their user credentials at
Twitter during the handshake instead
of just re-authenticating using their
existing Twitter session.

From abraham:

You can use oauth/authenticate and add
force_login=true as specified in
http://dev.twitter.com/doc/get/oauth/authenticate*.
This will prompt the user with a login
form.
