It appears to be a light with pass through power and a switch line.

There appears to be an error in that all three grounds should have been
connected (and attached to the box). A second possible error may be the
lack of remarking the color of the wire to the switch. I seem to recall
that current code requires marking the ends of the wire in this case.


It does, but I believe that that is a recent addition to the code so it
may not have been a violation when the work was done.

This house (built around 1969) has several switch loops, none of which
are marked. also the 240V circuits use ordinary 10/2 Romex
(black/white/bare), and aren't marked either.


Just put a strip of tape (red or black) around the end of any white
wires used for switch legs whenever you find them so future generations
aren't confused. no problem.
