Leviton Industrial Grade Pilot Light Toggle Switch, 120/277V AC, 20A, 1-Pole

The Leviton Industrial Grade Pilot Light Toggle Switch is a locking toggle AC quiet switch engineered for demanding commercial and industrial electrical applications. Based on Leviton model 1221-2L, this SPST 1-Pole device is rated 120/277-Volt AC at 20-Amp, giving electricians a dependable way to control lighting, motor, and equipment circuits from a single switching point. The switch combines a locking toggle mechanism with a quiet AC switching action and an integrated pilot light indicator, so operators can visually confirm circuit status while reducing the risk of accidental actuation. Finished in brown, this Industrial Grade toggle switch is built for the switching frequency and reliability demands of industrial and commercial facilities.

This toggle switch family is offered in multiple configurations, including the 2L pilot-light version and the PLC configuration, allowing specifiers to match the correct locking toggle switch to the circuit-indication needs of a given application. Whether used as a local disconnect, control switch, or status-indicating switch point, the 120/277-Volt AC, 20-Amp SPST 1-Pole rating supports general-purpose and industrial switching duties.

Key Features

  • Electrical Rating: Rated 120/277-Volt AC at 20-Amp, suitable for controlling lighting, motor, and general-purpose industrial and commercial loads.
  • SPST 1-Pole Configuration: Single-pole, single-throw (SPST) switching provides straightforward on/off circuit control from a single location.
  • Locking Toggle Design: The locking toggle mechanism helps guard against accidental or unauthorized actuation, an important safety feature in industrial settings.
  • AC Quiet Switch Operation: Designed as an AC quiet switch, it minimizes audible toggle noise during actuation.
  • Integrated Pilot Light: The built-in pilot light (2L configuration) gives a clear visual indication of circuit status, helping personnel quickly confirm whether a connected circuit is energized.
  • Industrial Grade Construction: Manufactured to Industrial Grade standards for durability and consistent performance under repeated switching cycles.
  • Brown Finish: Finished in brown for a standard industrial device appearance.
  • Configuration Options: Available in 2L (pilot light) and PLC configurations to match specific circuit-indication and switching requirements.

Leviton 1221-2L – Frequently Asked Questions

1) Will the Leviton 1221-2L toggle switch work on a 277V lighting circuit as well as 120V?
Yes. The Leviton 1221 industrial toggle switch is rated 120/277V AC at 20 amps, so the same device handles a 120V receptacle-branch or control circuit and a 277V fluorescent or LED lighting branch in a commercial building. That dual rating is why it gets specified for facilities running both voltages off the same hardware standard.
2) What is the difference between the Leviton 1221-2L and the 1221-PLC?
Both are the same 20A, 120/277V AC single-pole locking toggle switch body. The difference is circuit indication: the 2L is the pilot-light version, giving a visual confirmation that the controlled load is energized, while the PLC is the other offered configuration of the same locking toggle family. If your operators need to see load status from the switch point, order the 2L.
3) I need a 20A 120/277V toggle switch but the circuit is switched from two locations - what do I use instead of the Leviton 1221-2L?
The Leviton 1221 is a 1-pole (SPST) device, so it only controls a circuit from one point. For two switching locations at the same 20A, 120/277V rating, use the Eaton Arrow Hart industrial grade three-way toggle switch, AH-1223GY, which is a three-way device rated 20A at 120/277V. You give up the pilot light indication that the 1221-2L provides, but you gain control from two locations.
4) What is the closest straight equivalent to the Leviton 1221-2L if I don't need the locking toggle or pilot light?
For a plain heavy duty 20A single-pole toggle at the same duty level, the Pass & Seymour PS20AC3W is an industrial extra heavy duty specification grade 20A toggle switch. The Leviton 1221 is an industrial grade device with a locking toggle and, in the 2L configuration, a built-in pilot light; the PS20AC3W is a straight switch in white with no indicator, so it suits circuits where you do not need visual load-status confirmation or protection against accidental actuation.
5) We need a brown toggle switch to match existing devices - is the Pass & Seymour 660G a substitute for the Leviton 1221-2L?
They match on color but not on function. The Leviton 1221 is finished in brown, and the Pass and Seymour 660G Trademaster grounding toggle switch is brown satin thermoplastic, so they will look alike on a wall plate. The 1221 is an industrial grade device rated 20A with a locking toggle and pilot light in the 2L configuration, while the 660G is a Trademaster series grounding switch. If the circuit requires the 20A industrial rating or the pilot light, the 660G is not a replacement.
6) Can I use the Bryant 4801W on a 277V lighting circuit instead of the Leviton 1221-2L?
The Bryant 4801W is a 4-Series single-pole toggle switch rated 15A at 277V AC in white, so it is single-pole like the Leviton 1221 but carries a 15A rating rather than 20A, and it is a 277V device rather than 120/277V. On a 20A branch circuit or where the same switch must serve 120V and 277V applications, specify the Leviton 1221. The 4801W also has no pilot light, so it will not give the load-status indication the 1221-2L provides.
7) What does the locking toggle on the Leviton 1221 actually do?
The locking toggle mechanism guards against accidental or unauthorized actuation, so a passerby or a bumped panel door won't flip the circuit. That's the reason it shows up on local disconnects, machine control circuits, and equipment that should not be switched casually. If you don't need that protection, a standard industrial grade toggle like the Pass & Seymour PS20AC3W will do the plain on/off job.
8) Is a pilot light toggle switch the right choice for indicating a load in another room?
That is exactly what the 2L configuration is for. The integrated pilot light tells personnel at the switch whether the connected circuit is energized, which matters when the fan, pump, or exterior lighting it controls is out of sight. For a switch point where nobody needs load status, a plain grounding toggle such as the Pass & Seymour 660G Trademaster is the simpler device.
9) Is industrial grade overkill for a 20A switch, or does it matter?
Grade is about switching cycles and mechanical life, not just marketing. The Leviton 1221 is built to industrial grade for repeated actuation in commercial and industrial facilities, which is what you want on a machine control or disconnect point that gets thrown many times a day. For lighter-duty commercial work, the Pass & Seymour CS20AC3I is a 20A specification grade device, and the PS20AC3W is their industrial extra heavy duty specification grade version.
10) Will a 20A switch handle a 15A branch circuit?
Yes. A 20A rated switch can be used on a 15A circuit; the rating is a maximum the device can carry, not a requirement. The reverse is not true, so don't put a 15A device like the Bryant 4801W on a 20A branch. The Leviton 1221 at 20A covers both.
11) What color is the Leviton 1221 pilot light switch, and what if my other devices are white or light almond?
Brown, the standard industrial device color. If you are matching a building already trimmed out in another color, the comparable devices we carry include the Bryant 4801W in white, the Pass & Seymour 663LAG in light almond, the CS20AC3I in ivory, and the PS20AC3W in white. Bear in mind those are different devices, not color variants of the Leviton.
12) Why is it called an AC quiet switch?
The 1221 uses a quiet AC switching action, meaning the mechanism minimizes the audible snap when the toggle is thrown. It matters in occupied spaces, corridors, and anywhere the switch sits near a desk or patient area rather than in a mechanical room.
