Double sided tape?? WTF made you say that? Heheh

"isolate" doesn't mean glue together. It means to make electrically separate from each other. I.E. insert some sort of insulator between the two.
Insulating tape is one method, quick and easy. A thin bit of cardboard would be another. I'm sure there are 10's of other isolation methods applicable here.
Electrical tape is AFAIK another word for insulating (non conductive) tape.
