Pass & Seymour CS20AC Commercial Specification Grade 3-Way Toggle Switch, 20A 120/277V

Pass & Seymour CS20AC Commercial Specification Grade 3-Way Toggle Switch, 20A 120/277V

The Pass & Seymour CS20AC Commercial Specification Grade 3-Way Toggle Switch is rated 20A at 120/277V and engineered to meet federal specification standards for demanding commercial and industrial installations. This switch is available in Brown and Gray finishes so electricians can match device plates and interior finish schemes without sacrificing any electrical performance — both color options share identical 20A, 120/277V ratings, wiring methods, and construction. Side-wire terminals plus external screw-pressure-plate back wiring accept #14 - #10 AWG copper or copper-clad wire for fast installation and superior electrical connections. Rugged thermoplastic construction with a Matte finish shrugs off hard use, and the switch is cULus Listed and Federal Spec Listed for code-compliant performance in high-traffic commercial and government-spec wiring projects.
