Abstract

For miniaturizing and rationalizing the manufacturing process of contact devices for herring aids, it is proposed that an injection molded body be provided with metal contact springs according to the insert mold technology. Over and above this, wiring elements are applied on the injection molded body as interconnects. To this end, the injection molded plastic body provided with metal springs can be activated in specific patterns with, for example, a laser, and, subsequently, the activated portions are coated with conductive metal. Alternatively, the interconnects can also be printed onto the injection molded body.
