This power window master switch for Buick Regal features a two‑tone design of beige buttons and black base, integrally molded from high‑strength ABS plastic. The button layout and icons are identical to the original car, with delicate wear‑resistant surface, sensitive rebound and comfortable pressing feel. Pure copper terminals inside ensure stable conductivity and oxidation resistance. Molded strictly by OE standard, buckles, pins and dimensions precisely match the original car for direct plug‑and‑play replacement.
