Okay, so you think it's all wired properly. Fair enough. Seems kinda weird to me. Maybe I was initially thinking that there would be two hot cables coming into the switch box, and tying all those neutrals together seemed odd. But I guess that's probably not the case.

The distance from the switch to the outlet is about 15 feet. There's currently nothing plugged into the outlet, so there shouldn't be any, uh, flux(?), to cause induction, right? I mean, effectively, it's all open circuits.

I think I'm going to remove the outlet switch and test its resistances.
