A current breaker for automotive safety systems has a separating punch and a conductor formed with at least one localized decrease in thickness constituting a weakened separating point severable by the separating punch. This current breaker is made by overmolding the conductor in a plastic-injection mold with an encapsulation by a method having a first step of forming the separating point of the conductor in the plastic-injection mold before or during overmolding and a second step of forming with the mold above and below the conductor in the encapsulation a passage fully exposing the separating point and dimensioned to hold the separating punch.

Method of making a current breaker

A disconnect has a housing defining a cavity, a busbar fixed in the housing and extending through the cavity, a piston movable in the cavity past the piston for breaking a piece out of the busbar, and a plurality of metallic filter elements exposed in the cavity below the busbar and electrically connecting with the piece on activation of the disconnect. An igniter displaces the piston in the cavity into engagement with and past the busbar so as to break the piece out of busbar and displace it past the filter elements such that an arc created by breaking out the piece is drawn by the piece away from the busbar and energy of the arc heats and is dissipated in the filter elements.
