The aim of the invention is to produce a conductor (14) for a circuit breaker (11), said conductor having a printed circuit board (14c) to be separated between two conductor ends and additionally having a conductor encapsulation (15) that has a cavity (20) in which the printed circuit board (14c) is located. This is achieved in that a plastic melt is injected, via at least one gate (21), into an injection mold, in which the conductor (14) is located. According to the invention, the gating process (21) is carried out from out of the cavity (20), through which the conductor passes, wherein the plastic melt flows from the gate (21) to the actual conductor encapsulation (15) through a runner (22; 24a-24d; 26a, 26b). In the process, the gate (21) can remain in the completed circuit breaker (11).

Packages, systems, and methods of the present disclosure are generally directed to the use of side gating in injection molding to form packaging for contact lenses. As compared to gating along a top surface of a contact lens package, the use of a side gate in injection molding to form a package for contact lenses may significantly reduce the time required to cool plastic in the injection mold, thus offering potential to reduce the overall cycle time for the injection molding process and increase fabrication throughput of the package.
