I am not exactly sure I understand your question, but if I understand
correctly the wire broke off near the terminal screw at a switch.

If that is true, the weakness could be caused by someone using
strippers incorrectly. If they used the wrong size hole in wire
stripers this can cause a weakness.

And if that's the problem, then you can just strip more of
the insulation off the end. If the wire is too short to
have enough to properly reach the switch, then add another
6" piece and use a wire nut to secure it to the existing wire.
