Eaton 271B-BOX – Frequently Asked Questions

1) Can the Eaton 271 duplex toggle switch control two separate lighting circuits from one gang?
That is exactly what it is built for. The Eaton 271 puts two single-pole toggles in a single duplex housing, so you get two independent on/off circuits in one device opening instead of a two-gang box. Each toggle is a maintained-closure single-pole, so each one holds its state until you flip it back.
2) Will a 15A Eaton 271 duplex toggle switch work on a 277V lighting circuit?
Yes. The 271 is rated 15A at 120/277V, so it will switch 277V commercial fluorescent or LED lighting branch circuits as well as standard 120V loads. Keep the connected load at or below 15 amps; on a 20A branch circuit you need a 20A-rated switch instead, such as the Pass & Seymour CS20AC3I specification grade 20A toggle or the Leviton 1221.
3) What wire size do the terminals on the Eaton 271 duplex switch accept?
Screw terminals sized for #14-12 AWG copper, wired either back or side. That covers the usual 14 AWG on a 15A circuit and 12 AWG runs. Anything larger than 12 AWG will not land on this device.
4) Does a duplex toggle switch fit a standard single-gang box and cover plate?
The Eaton 271 is a flush-mount device on a standard strap and takes a single-gang opening, but it needs a duplex-style two-toggle plate, not an ordinary single-toggle plate. Device body dimensions are 4.19 x 1.3 x 1.08 inches. Check box fill and depth before you crowd two switch legs plus travelers into a shallow box.
5) What is the difference between the Eaton 271B-BOX duplex toggle switch and a single toggle switch like the Pass & Seymour CS20AC3I?
The Eaton 271B-BOX is a duplex-style device with (2) single-pole toggle switches in one housing, rated 15A at 120/277V, so one gang controls two separate circuits. The Pass & Seymour CS20AC3I is a single commercial 20A specification grade toggle switch in ivory, giving one switched circuit per device. If you need two switch legs behind a single gang opening, the Eaton duplex is the one; if you need a single higher-amperage spec grade switch, the CS20AC3I fits.
6) I need a 20A switch instead of the 15A Eaton duplex toggle - what should I use?
The Eaton 271B-BOX is rated 15A at 120/277V. For a 20A circuit, the Leviton 1221 is an extra heavy-duty industrial specification grade SPST toggle switch rated 20A at 120/277V, and the Pass & Seymour PS20AC3W is an industrial extra heavy duty specification grade toggle in white. Both are single switches rather than duplex, so you would need two devices and a two-gang box to replace the dual control the Eaton provides in one opening.
7) Can I use the Bryant 4801W in place of the Eaton 271W-BOX duplex toggle switch?
Not as a direct swap. The Bryant 4801W is a 4-Series single-pole 15A 277V AC toggle switch in white, which gives one switched circuit. The Eaton 271W-BOX is a duplex housing holding (2) single-pole toggles rated 15A at 120/277V, controlling two circuits from one gang. The Bryant works if the opening only needs one switch leg; if the box is wired for two, you would need two Bryant devices and a two-gang plate.
8) What colors does the Eaton 271 duplex toggle switch come in?
Two: brown, ordered as 271B-BOX, and white, ordered as 271W-BOX. If you are matching light almond or ivory devices already on the walls, look at another line instead, such as the Pass & Seymour 663LAG in light almond or the CS20AC3I in ivory.
9) Is commercial grade good enough, or should I spec an industrial grade toggle switch?
The Eaton 271 is a commercial-grade device with a thermoplastic body and brass contacts, which suits offices, retail, and general institutional lighting control. For high-cycle or abusive areas, or where the spec calls out extra heavy-duty, step up to a specification-grade single-pole such as the Leviton 1221 or the Pass & Seymour PS20AC3W. Note those are single switches, not duplex, so two openings or two devices are needed to match the dual-circuit function.
10) Does the Eaton 271 duplex switch have a pilot light to show when the load is on?
No indicator. Both toggles are plain maintained-closure switches with no lamp. If the crew needs to see from the hallway that a fan or exterior light is energized, use a pilot light device such as the Leviton 1201PLC or the Leviton 1221-2L, both single-pole pilot light toggles.
11) What is a simpler residential-style alternative to the Eaton 271W-BOX commercial duplex toggle?
The Eaton 271W-BOX is the white version of a commercial grade duplex toggle with (2) single-pole switches. For a lighter-duty single toggle, the Pass & Seymour 660G TradeMaster grounding toggle switch comes in brown satin thermoplastic and the 663LAG TradeMaster grounding toggle comes in light almond thermoplastic. Those are single switching positions in a standard thermoplastic body, so use them where only one circuit is being controlled at that location.
12) I need an ivory or light almond switch to match existing devices - the Eaton duplex only comes in brown and white.
The Eaton duplex toggle is offered as 271B-BOX in brown and 271W-BOX in white. For other device colors, the Pass & Seymour 663LAG TradeMaster grounding toggle is light almond thermoplastic and the Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle in ivory. Both are single toggle devices, so confirm whether the opening needs one or two switched circuits before ordering.
13) Can this switch go in an unheated warehouse or a mechanical room that runs hot?
Operating range is -20 to 60 degrees C, so unconditioned storage space, loading docks, and warm mechanical rooms are within range. Outside that band, pick a different device.
14) Is the Eaton 271 duplex toggle switch RoHS compliant for our procurement spec?
Yes, RoHS compliance is stated for the device. That is the compliance item carried on record for the 271 series.
