I think you're right. I did it the other way, and I'm uncomfortable with it. That's why I asked. This type of switch has a common feed and three outputs for the hot wire, and I originally installed it so the common hot feed was at the top, not thinking about the switch positions. It's also the way the printing on the switch faced. Then, I got to thinking, it makes a difference whether the switch is to the right or the left of the doorway, so in one of the cases the switch has to be installed "upside down". It will only take me a couple of minutes to change it. Thanks.
Junkman, I originally set it up somewhat they way you said -- I put the ceiling light, which is part of the vent unit, on top. Then, I did it in order of their physical location. The fan was next, and then the lights over the sink, because they were lower than the ceiling unit. Made sense to me at the time, but after using it for a few days, I think I'll put the ceiling light on top, then the wall lights, then the fan. I have to move them around, anyway, to turn the switch over.
(Sigh) No wonder it takes me so long to get these projects done, when I spend so much time thinking about such a trivial matter. But, no one else will see all the work I did to install this unit; they'll only interact with the switches, and will judge me accordingly.
