Function Check Before Batch Production

LW42 is usually selected by switching program and installation structure, not only by current rating. For OEM projects, provide the target panel layout, handle legend, position count, and wiring sequence so Shieldhz can confirm contact stage count, terminal arrangement, marking, and document package.
