The Corbin locking mechanism restricts operation to authorized personnel, making this switch well suited for lighting circuits, HVAC fan controls, and other branch circuits in facilities where accidental or unauthorized shutoff carries operational or safety consequences. Licensed electricians install this switch in standard wall boxes as part of a controlled-access electrical layout.\u003c\/p\u003e\n\u003cp\u003eThe 1191N is used in commercial buildings, schools, hospitals, warehouses, and industrial facilities where branch-circuit switching must be restricted. Its 277-volt rating makes it a direct fit for single-phase fluorescent and LED lighting circuits fed from 480Y\/277-volt distribution panels, which are standard in North American commercial construction. The locking feature requires a Corbin key to toggle the switch, preventing tampering by unauthorized building occupants.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-pole configuration rated 20A at 277V AC for commercial lighting and fan circuits\u003c\/li\u003e\n  \u003cli\u003eCorbin key lock mechanism restricts switch operation to authorized personnel\u003c\/li\u003e\n  \u003cli\u003eSuitable for 480Y\/277V panel-fed branch circuits common in commercial builds\u003c\/li\u003e\n  \u003cli\u003eDesigned for standard wall-box installation by licensed electricians\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or specification-grade locking AC switch for commercial and industrial branch-circuit applications requiring a single-pole 20A 277V device with Corbin key control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the branch circuit at the panel and verify zero voltage with a calibrated meter before wiring. Ensure the wall box and cover plate are compatible with the switch body dimensions.
