Not sure this will make sense without photos.

I have a single pole switch that does not control anything in my kitchen and could never figure out what it went too.

Later I found what looks like the top side of a fluorescent light fixture with a one rigid conduit going to it in the deadspace of a ceiling bypass above, (probably 40+ years old). At some point new cabinets were put in and the underside of this fixture is not accessible anymore from below.

I am guessing this switch controlled this abandoned fixture. I am also guessing the old fixture would be against code now(ie: wiring not accessible).

If indeed the switch sending power to this fixture, should I just disconnect the switch and snip and wirenut the power going to switch and forget about the fixture?

I wonder if this could be a hazard. Is this something I should address or leave the current configuration in place?

ANy ideas?
