A switch box is an electrical housing that mounts and protects one or more manual switches (rocker, toggle, push‑pull) used to control lights, fans, or auxiliary equipment on a heavy‑duty truck or trailer.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
You would replace a switch box when the original housing becomes cracked, corroded, or the mounting tabs break, or when adding new circuits and need a fresh, clean mounting point. This part number appears to be a generic replacement switch box for electrical and lighting circuits, but without a manufacturer cross‑reference we cannot confirm its exact application.
