Classic Battery Terminals

[DanLewis]

I tried salvaging a lever from a micro switch, but this particular one was made of steel, so I couldn't solder the wire to it

At this point, I think the best idea may be to salvage a terminal from a junk calculator. The bends in the terminal are critical to the elasticity, and snatching an already made terminal will assure the bends are made correctly.

I have never seen one of those 4.5 V flat batteries before, and I would hate to buy one just to use it for the terminal.
