The Leviton Commercial Specification Grade 3-Way Toggle Switch is engineered for reliable, quiet switching in demanding professional electrical environments. Rated 20A at 120/277V, this AC toggle switch is built to commercial/specification grade standards, meaning it is manufactured to tighter tolerances and higher durability requirements than standard residential-grade devices. It is designed to control a fixture or circuit from two separate switch locations, making it a practical solution for stairways, hallways, and multi-entry rooms. The switch is available in Ivory and White finishes, allowing installers and designers to match existing wall plates and interior color schemes without sacrificing performance.

Key Features

Leviton CS320-2I – Frequently Asked Questions

1) Can a Leviton 1223-SW 3-way toggle switch run on a 277V lighting circuit?
Yes. The Leviton commercial spec grade 3-way toggle is rated 20A at 120/277V AC, so it works on standard 120V branch circuits and on 277V lighting circuits common in commercial buildings. Same device either way, no separate part number for the 277V application.
2) What does a 3-way switch do, and do I need two of them?
A 3-way switch controls one fixture or circuit from two separate locations, which is what you want at the top and bottom of a stairway, at both ends of a hallway, or in a room with two doors. It takes two 3-way switches wired with travelers to make that pair work, so order in twos for each opening you are controlling. If you only need control from one spot, a single-pole switch is the correct device instead.
3) I need a single-pole switch, not a 3-way. What should I order instead?
Don't use this one. The Leviton 1223-SW is a 3-way device meant for two-location control and it will not wire correctly as a plain on/off. For single-location control, the Bryant 4801W 4-Series is a single-pole 15A 277V AC toggle in white, and the Pass & Seymour TradeMaster grounding toggles (660G in brown satin thermoplastic, 663LAG in light almond) are other single-location options we carry.
4) What is the closest equivalent to the Leviton 1223-SW 3-way toggle switch from another manufacturer?
The Eaton Arrow Hart three-way toggle switch, part AH-1223GY, is the nearest match. Like the Leviton, it is a three-way toggle rated 20A at 120/277V, so it drops into the same three-way circuit controlling one fixture from two locations. The Eaton is an Arrow Hart series device in gray, while the Leviton comes in white and ivory, so confirm the color against the wall plates already on the job.
5) Can I use a Bryant 4801W in place of the Leviton 3-way toggle switch?
No. The Bryant 4801W is a single-pole 4-Series toggle switch rated 15A at 277V AC. Single-pole switches control a fixture from one location only and have one traveler terminal fewer than a three-way device, so it cannot be wired into the two-location three-way circuit the Leviton 20A 120/277V three-way switch is built for. Use the Bryant only where a single switch controls the load.
6) Will a 20A switch work on a 15A lighting circuit?
Yes. The Leviton 1223-SW is rated 20A at 120/277V, and a device rated above the circuit ampacity is fine. Plenty of property managers standardize on the 20A spec grade device across a building so one part number covers both 15A and 20A branch circuits.
7) What colors does the Leviton commercial 3-way toggle come in, and what are the part numbers?
Two: white is part number 1223-SW, ivory is CS320-2I. Both are the same 20A 120/277V 3-way toggle, so pick by what your existing wall plates and other devices are.
8) Will this Leviton switch fit my existing wall plate and box?
It uses a standard toggle-style actuator, so it drops into existing toggle wall plates and gang boxes on a straight retrofit. You are swapping like for like on the faceplate cutout, which is what makes it a common replacement device in occupied buildings.
9) What is the difference between a commercial specification grade switch and a residential one?
Spec grade devices are built to tighter tolerances and higher durability requirements than standard residential-grade switches, with more mechanical strength and better contact reliability. That matters in offices, retail, corridors, and multi-family common areas where a switch gets operated hundreds of times a week. For a low-traffic closet in a house, residential grade does the job.
10) If I am standardizing a building on one brand of 20A spec grade toggle, what are my options besides Leviton?
Two lines cover the same 20A specification grade territory. Pass & Seymour has the CS20AC3I commercial 20A specification grade toggle in ivory and the PS20AC3W industrial extra heavy duty specification grade toggle in white. Eaton's Arrow Hart AH-1223GY is an industrial grade three-way toggle at 20A, 120/277V in gray. The Leviton runs 20A at 120/277V in white and ivory, so if your plate colors are white and ivory, the Leviton and the two P&S devices align on color across the facility.
11) Is there another ivory 20A specification grade toggle switch if the Leviton CS320-2I is not the one I want?
Pass & Seymour offers the CS20AC3I, a commercial 20A specification grade toggle switch in ivory. It matches the Leviton CS320-2I on ivory color, 20A rating, and specification grade construction, so it suits the same commercial lighting circuits and matches the same ivory wall plates.
12) What should I use instead of the Leviton 1223-SW for a heavy abuse industrial area?
The Pass & Seymour PS20AC3W is an industrial extra heavy duty specification grade toggle switch in white, built a step above standard commercial spec grade for rough service areas. It is a 20A device like the Leviton 1223-SW and comes in white, so it matches the same plate color. Note it is a single device rating class decision, not a wiring change - verify the switching configuration you need for the circuit before ordering.
13) Is there a quieter switch option for hotel guest rooms or apartments near bedrooms?
This Leviton toggle is built for quiet actuation, cutting the sharp click you get from a standard toggle. That is the reason it shows up in hospitality and multi-family corridors and units where a switch next to a sleeping area gets used at night.
