Leviton S11-05603-2IS 3-way Decora Switch 15A 120 277V

Product Description

The LEVITON MFG CO S11-05603-2IS is a 3-way Decora-style toggle switch rated for 15 amps at 120 and 277 volts. It supports motor loads up to 1/2 HP at 120 volts and 2 HP at 240 volts. The switch features dual termination options: Quickwire push-in terminals for faster installation and side-mounted terminal screws that accept copper wire up to No. 10 gauge. This combination reduces labor time on multi-switch circuits without sacrificing code-compliant wiring flexibility. Licensed electricians typically install this device in residential and commercial lighting circuits requiring 3-way switching control.

This switch is suited for residential and light commercial applications where two switching points control a single load, such as stairwells, hallways, large rooms, and corridor lighting. The 277-volt rating extends its use to commercial fluorescent lighting circuits commonly found in office buildings, warehouses, and retail spaces. The Decora rocker-style form factor fits standard Decora wallplates. Package quantity is 10 units per package, making it practical for multi-room installations or service stock.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify zero voltage with a meter before any wiring work. Both the Quickwire push-in ports and the side-screw terminals are rated for copper wire only — do not use aluminum conductors. Confirm that the wallplate and electrical box are compatible with the Decora form factor before securing the device.
