Leviton 1221-2I – Frequently Asked Questions

1) Is the Leviton 1221 a single-pole or three-way switch?
Single-pole, single-throw, one pole. It gives simple on/off control of one circuit from one location. If you need two switch locations controlling the same lights, this is the wrong device and you want a three-way, such as the Eaton Arrow Hart Industrial Grade three-way toggle switch rated 20A at 120/277V.
2) What is the closest cross-brand equivalent to the Leviton 1221 20A toggle switch?
The Pass & Seymour PS20AC3W is the nearest match in another brand: it is an industrial extra heavy duty specification grade toggle switch, the same construction class as the Leviton 1221, which is an extra heavy-duty industrial specification grade device rated 20A at 120/277V. The difference to confirm before ordering is device color - the Pass & Seymour is White, while the Leviton 1221 comes in Ivory (1221-2I) and Red (1221-2R).
3) How does the Bryant 4801W compare to the Leviton 1221 for a 277V lighting circuit?
The Bryant 4801W is a 4-Series single-pole toggle switch rated 15A at 277V AC in White. The Leviton 1221 is also single-pole but rated 20A at 120/277V, so it covers both 120V and 277V circuits and carries the higher amperage. If the branch circuit is 20A, the Leviton 1221 is the one that matches; for a 15A 277V-only lighting circuit the Bryant is the lighter device.
4) Is a spec-grade switch worth it over a residential switch for a high-traffic building?
For openings that get actuated dozens of times a day, yes. The 1221 is Extra Heavy-Duty Industrial Specification Grade, built for high cycle counts, where a standard residential-grade 15A switch is not. If you are standardizing a facility, a 20A spec-grade device also covers 20A branch circuits without derating the switch to the load.
5) What other brands make an equivalent 20A specification grade toggle switch?
Pass & Seymour PS20AC3W is the closest match, an industrial extra heavy duty specification grade 20A toggle in White. The Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle in Ivory if you want to match an Ivory device line. Bryant's 4-Series 4801W is a single-pole 15A 277V switch in White, so it is a step down in amperage, not a direct swap on a 20A circuit.
6) Can I replace an old brown or almond toggle switch with the Leviton 1221?
Electrically yes on a 120V or 277V single-pole circuit, but the 1221 is only offered in Ivory and Red, so it won't color-match a brown or light almond device line. For those, the Pass & Seymour 660G Trademaster comes in brown satin thermoplastic and the 663LAG in light almond.
7) Can a Pass & Seymour TradeMaster 660G or 663LAG be used in place of the Leviton 1221?
They are different device classes. The Pass & Seymour 660G and 663LAG are TradeMaster grounding toggle switches in thermoplastic - 660G in Brown Satin and 663LAG in Light Almond - general-purpose grounding devices. The Leviton 1221 is an extra heavy-duty industrial specification grade SPST switch rated 20A at 120/277V, specified where frequent actuation is expected. Where a job drawing calls for a spec grade 20A device, the TradeMaster parts are not a like-for-like swap.
8) Can I use the Leviton 1221 to switch a 20A receptacle circuit, not just lighting?
Yes. At 20A, 120V it handles general-purpose lighting and receptacle branch circuit switching, and the description calls out panelboard and load center switching along with general-purpose lighting and receptacle circuit control. It is a single-circuit on/off device, so one 1221 controls one circuit.
9) Is the Leviton 1221 a quiet switch, or does it snap loudly?
It uses an AC quiet toggle mechanism, so the actuation is low-noise. That matters in offices, exam rooms, classrooms and hotel corridors where a hard-snapping switch gets complaints.
