Abstract

A method for producing electrical contacts (30) that can be applied in particular to the web of rails and the like, the method consisting in the steps of:
  • preparing a stub (1) of copper pipe having gauged dimensions,
  • inserting the stub (1) in a die (10) of a press,
  • performing a cold deformation to form a flanged head at the end of an internally hollow stem (21), and
  • extracting the resulting electrical contact (30) from the die.
