Describe the bug
Several switch statements in cFE are missing a default case and/or a terminating break in the default case.

Expected behavior
Relevant coding standards require that all non-empty switch cases (including default) are terminated by an unconditional break.

This is considered defensive coding for future code changes and improves consistency across cFE.
