For a one off, I would consider a spring contact from a lantern battery.
For a production source any spring or stamping manufacturer should be
able to produce what you want.  You probably want a bronze spring rather
than steel, and NOT stainless if you want to solder it to the PCB.

In the USA some manufacturers are Keystone, Seastrom, Small Parts Inc.
