I am attempting to make a small piece of jewelry that has a 3mm 3v button battery in it. I would like to use one of those little clip things that hold the battery in place and make the contacts to the wiring like in most watches, but I don't know what those thingies are called, or where to purchase them. Any info would be helpful. The battery type I am thinking of using is the CR2032 size, very small, so making my own clip would be hard. also are there heat-less solder I can use, or is heat-less not very good?
