I replaced all the faceplate sockets in my home although they weren't that old (all dated 2004) some were sparking/crackling and not making proper contact when the switch was operated.
I replaced them all with brushed steel BG (British General) faceplates. The one in our bedroom used to switch on on its own and is actually now stuck in the 'on' position. I can operate the switch back to 'off' but when I let go, it flips back to 'on'. One in the extension occasionally sticks, too.
I wonder if your switch is suffering the same problem.
