No outlets with buttons on them. No meter either. I bought outlets and switches out of the 47 cent bin at home depot. Maybe I'm getting what I paid for.
The ones with buttons on them are the GFCI ones I mentioned... they click off if there's a ground fault... (after a bunch of years, they might need replacing because they get tired and click off for no good reason)... they're for bathrooms and other places that get wet... if you're messing with them, it's well worth the $5 or $10 it cost to get the little ground fault testing gizmo I mentioned earlier... (there are other ways to do it, but it's well worth a couple bucks to make it easy and idiot-proof...) http://www.amazon.co...nd fault tester
Get a multi-meter... if you're messing with wiring, it's as much of a basic tool as is screwdriver... a cheap one will do, you don't need a fancy one for this kind of task... mine cost like $10... (just make sure you don't get home with one and then discover you need to make another trip to get the batteries!)... if you have one, you adjust the dial to the proper setting and then use the 2 probes to see if you have 120V (or 115V or whatever) coming out the other side of the outlet... if you don't have one, then you need to lick your fingers and touch the poles to see if you get shocked... believe me, having a cheap little multi-meter is way, way better... http://www.amazon.co...5751582&sr=1-23
