How do you take them out of the wall. There are no screws. Are they pressed into the hole? Are there tabs somewhere to release them? The GFIC outlets have screws.
If I remember right, the outer ring/trim piece just pops off. Thin blade under it and work it off carefully so as not to break it. Then there should be two screws you have to loosen. I don't think they have to come all the way out, but not sure. I think they just clamp a piece inside the wall so the receptacle and wall box is tight. After you get it loose enough you should be able to tip it to get it out.
Anyway that is the way I remember mine.
Make sure you have the power disconnected.
Let us know how you make out.
Lloyd is right I just had to replace a light switch Darn a failure after 8 years of service and towed over 30,000 miles
