Industrial wire harness manufacturers in Switzerland

V-Tronic, based in Fällanden, Switzerland, has assembled cables since 1980, offering crimping, stripping, tinning, and cutting-to-length services that range from single wire strands to complete, ready-to-connect wiring harnesses. It runs a varied machine park for small, medium, and large series, with in-process visual and dimensional checks using magnifiers and calipers, and develops custom tooling for individual customer specifications.

Werner Forrer, headquartered in Uster, Switzerland, produces custom-made cable assemblies including flat cables, round cables, flexible cables, and wire strands, and also assembles simple and complex cable/construction groups. It sources raw material and components from established suppliers and tests each product with continuity and high-voltage checks, cross-section analysis, pull tests, and crimp-height measurement before shipment, handling both labor-intensive processes and high quantities.

Walter Frei, founded in 1967 in Jona, Switzerland as an electrical-machine repair business, later added its own cable-assembly department alongside choke/coil manufacturing and, since 2017, mechanical machining through subsidiary a.merki ag. Its cable assembly ranges from simple flat cables to complex wiring harnesses or cable sets using connectors and sockets from all major manufacturers, with stated specialties in cabling for rail vehicles and electromobility, and small-series production is offered alongside large runs.

Kabelsysteme H. Fenner, headquartered in Pfäffikon ZH, Switzerland, is a manufacturer of special cables, cable systems, wiring harnesses, and cable assemblies. Its work includes fitting connectors to data and coaxial/RF cables and to motor/axis-drive lines, plus device and enclosure wiring linking switches, sockets, displays, and circuit boards, with connectors subjected to bend-behavior testing during and after production.
