That stretch is possible if you have a good hunk of SW. Otherwise, one could take a bit of stainless steel wire and tape it to one of the contacts (+) and then down the side of the battery towards the other pole so that the two are easier to touch to the SW. Both the stainless steel wire and elctrical tape or duct tape are in my kit.

Of course, those with brass wire would be out of luck as it is a poor conductor of electricity. <img src="images/graemlins/frown.gif" alt="" />
