1. A method of making a current breaker for automotive safety systems having a separating punch, the method comprising the steps of:
positioning a conductor and two cores in a mold,
overmolding the conductor and the cores in the mold with an encapsulation while forming with the cores passages extending oppositely away from a central part of the conductor in the encapsulation,
with the cores in the passages, forming the overmolded conductor in the mold with a localized decrease in thickness constituting a weakened separating point during the overmolding, and
removing the cores from the passages and then providing in one of the passages a separating punch for severing the conductor at the separating point.
