Leviton S12-05603-2WS 3-way Decora Switch 15A 120/277V

Product Description

The LEVITON MFG CO S12-05603-2WS is a 3-way Decora-style grounding switch rated for 15 amps at 120/277 volts. It supports single-phase motor loads up to 1/2 HP at 120 volts and 2 HP at 240 volts. The switch offers two wiring methods: Quickwire push-in terminations for faster installation and traditional side-wiring via terminal screws that accept up to No. 10 copper wire. This combination makes it a practical choice for residential and light commercial wiring projects where speed and flexibility on the job matter. It ships in a package quantity of 10 units, making it well suited for multi-room or multi-unit installs. UL listed and backed by a limited 10-year warranty.

This switch is designed for 3-way switching applications where a single load, such as a lighting circuit or small motor, must be controlled from two separate locations. Common install scenarios include stairwells, hallways, and large rooms with multiple entry points. The Decora form factor fits standard decorator-style wallplates, which are widely used in both residential construction and light commercial settings. Electricians working on new construction or retrofit projects will find the dual-wiring options reduce time per device on high-volume installs.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the branch circuit breaker and verify the circuit is de-energized with a non-contact voltage tester before wiring. When using Quickwire push-in terminals, ensure wire is stripped to the correct length per the strip gauge on the device. For 3-way applications, confirm traveler wire routing between both switch locations before energizing the circuit.
