Del City Electrical Connectors
About Del City: Over 75 Years of Professional Electrical Supplies
Del City has been a trusted name in professional-grade electrical and transportation supplies since 1947. Del City was founded by Harold Swartzendruber, who began with a straightforward mission — selling high-quality wire directly to customers who needed reliable electrical components. From those humble roots, the company grew into one of the most comprehensive electrical supply brands in the industry, eventually relocating its headquarters to Menomonee Falls, Wisconsin, where it continues to operate today.
A Catalog Built for Every Electrical Application
Del City's strength lies in the sheer breadth of its product lineup. With over 15,000 electrical and transportation supply items in stock, the brand serves professionals and enthusiasts working across automotive, truck, trailer, marine, specialty vehicle, recreational vehicle, emergency vehicle, and industrial OEM/MRO applications. Whether you're building a custom wire harness for a fleet vehicle, rewiring a boat, or sourcing circuit protection components for heavy equipment, Del City maintains a deep inventory designed to meet virtually any 12V electrical requirement.
At the core of the catalog is an extensive selection of electrical wire and cable — over 1,000 options spanning primary wire, cross-link wire, marine-grade tinned wire, shielded wire, battery cable, welding cable, trailer cable, and more. These wires come in a wide range of gauges, colors, and spool lengths, all adhering to industry standards for easy identification.
Equally robust is Del City's offering in wire connectors and terminals, covering everything from Weather Pack and DEUTSCH connectors to Metri-Pack sealed connectors, ring terminals, heat shrink butt connectors, and Anderson power connectors. For circuit protection, the brand stocks DC circuit breakers ranging from 10A to 200A in Type 1, Type 2, and Type 3 reset styles, alongside an extensive line of fuses, fuse blocks, fuse holders, and fuse panels suited for automotive, marine, and industrial use.
The lineup also includes a wide variety of electrical switches — toggle, rocker, push button, battery disconnect, ignition, and turn signal styles — as well as relays, loom and wire management products, cable ties, grommets, heat shrink tubing, hand tools, and lighting accessories for vehicles and work environments.

Del City's customer base is diverse, ranging from independent repair technicians and fleet managers to wire harness manufacturers, marine builders, and emergency vehicle upfitters. The brand's catalog-driven heritage means it has long prioritized having the right part in stock when professionals need it — a reputation backed by decades of customer relationships across virtually every segment of the transportation and electrical industries.
