20A IV. 3W 120/277V AC SWITCH

20A IV 3W 120/277V AC SWITCH (Product Description)

A 20-amp, specification-grade toggle switch designed for commercial and industrial lighting control applications. This device is commonly used in building electrical systems where both 120V and 277V AC circuits are present.

Product Description

This is a 20A, 120/277V AC, 3-way (3W) wall switch with an IV (ivory) color finish, used for reliable control of lighting or electrical loads from one or multiple locations. It is built for commercial-grade durability and supports higher-voltage lighting systems commonly found in offices, schools, warehouses, and industrial buildings.

The “3W” designation indicates a 3-way switching configuration, allowing a load (such as lights) to be controlled from two different switch locations.
