Abstract
A barrel for a spring probe has a tubular body and a crown shaped terminal end for discrete point contact of the barrel. The terminal end has a drawn opening with a substantially circular cross-sectional dimension and a crown shaped contact integrally formed in the circular opening. There are several possible shapes for the crown shaped contact including pointed projections where multiple triangular shapes are placed end to end around the circumference of the terminal end, a corrugated shape with squares spaced apart around the circular edge, a wavy shape along the circular edge, or a rounded shape around the edge.
