Sounds like another personal preference thing, I guess.
Keeping them the same throughout the home definitely sounds like a good idea.
First one of these I came across I had my clock plugged into one side of a duplex on the opposite side of the bed to the light. I thought the clock had gone faulty for a couple of days until I suddenly realized what was happeing!
Duplexes here have only one set of terminals, so this split isn't possible.
I'm with you. That makes the most sense to me, but it doesn't seem to matter otherwise.
I don't see much of this around. Coincidentally, I just got a request for it the same day you posted this Q! I can probably count the # of requests I've had for this on 1 hand for almost 20 yrs. I do volunteer it ocassionally as a solution to unsure usage of a room, but not as a general rule.
After reading all the posts I figured I would put my 2 cents in. Figuring 9 times out of 10 there will be something plugged into a switched side of the outlet it would only make sense to put the switched part on the bottom. Because if it was on top there would always be a cord dangling over the open outlet. Makes sense doesn't it???
