The 277W‑BOX is a commercial‑grade duplex combination switch designed by Eaton’s Cooper Wiring Devices to provide both functionality and reliability in demanding electrical environments. This specialty device combines a single‑pole toggle switch with a built‑in neon pilot light, making it ideal for applications that require visible confirmation of circuit status or load activity.
Engineered with a durable thermoplastic housing, brass hardware, and a rugged mounting strap, the 277W‑BOX excels in high‑traffic commercial spaces where long‑term performance is essential. The integrated pilot light operates on its own voltage rating and helps occupants quickly determine whether a connected load or circuit is energized. Its clean white finish blends seamlessly with modern interiors and standard wall plates, making it suitable for both new installations and upgrades.
