Glad you found it. As soon as I pulled that switch I imagined what had happened with yours, minus the previous owner's input. Those wires are so tight one of the two black could easily pull itself back through the hole. Mine has the delay relay, so the black/white has multiple functions, but even if the delay relay is not working the dome light should still switch (without delay) through the solid black wires.



See if the caption here matches your understanding.

Thanks,
