If you need contacts that are 'springy' you would be better off using
phosphor-bronze contacts salvaged off something else. You can steal
them from a junk transistor radio or other portable equipment. Ordinary
steel, copper, or brass won't retain shape for long. I used to do 'drop
tests' on medical devices with battery compartments earlier in life.
