Leviton 1221-PLR – Frequently Asked Questions

1) Will a pilot light switch work if my switch box only has a switch leg and no neutral?
A lighted pilot toggle needs a neutral in the box to power the lamp, since the indicator is energized independently of the load. On a switch-leg-only box you would either pull a neutral or use a plain toggle instead, such as the Pass & Seymour TradeMaster grounding toggle. Check the box before ordering the 1201-PLC or 1221-PLR.
2) I need a three-way switch instead of a single pole - what should I order?
The Leviton 1201-PLC and 1221-PLR are 1-pole devices, so they only do straight on/off from one location. For two-location control, the Eaton Arrow Hart industrial grade three-way toggle switch, catalog AH-1223GY, is rated 20A at 120/277V and is built to the same industrial grade. Note that the Eaton three-way does not carry a pilot light, so a stairwell or corridor run switched from both ends gives you the three-way function but not the lit status indication.
3) My circuit is 277V, not 120V - can I use the Leviton pilot light toggle switch?
No. The Leviton 1201-PLC and 1221-PLR are rated 120V. For a 277V AC lighting circuit, the Bryant 4801W is a 4-Series single-pole 15A 277V AC toggle switch in white, and the Eaton Arrow Hart AH-1223GY is rated 120/277V in a 20A three-way configuration. The Bryant is the single-pole match for a 277V ballast or LED driver circuit typical of commercial fluorescent and high-bay lighting.
4) What does the pilot light on the Leviton 1201-PLC actually indicate?
The integrated pilot light with a clear lens gives an at-a-glance read on circuit status, which is why these get used on loads you cannot see from the switch location: attic fans, remote mechanical room lighting, exterior or crawlspace circuits, equipment in a panelboard-adjacent space. If you only need plain on/off control in the same room, a standard toggle without the lens does the job.
5) Is an industrial grade toggle switch worth it over a residential one for a commercial building?
For high-use openings, yes. This Leviton is built to industrial grade specs for durability in commercial and industrial environments, with a quiet AC mechanism that keeps noise down in occupied spaces. Residential grade devices are built for far lower cycle counts. If you are standardizing a facility and want a comparable heavy-duty device without the pilot light, the Pass & Seymour PS20AC3W is an industrial extra heavy duty specification grade toggle, and the CS20AC3I is a 20A commercial specification grade option.
6) I need the switch to match brown or light almond devices already in the units - what are my options?
The Leviton pilot light toggle switch is a clear-lens device built around the illuminated indicator, so color matching works differently than with a plain switch. Where a standard non-lit switch will do and the finish has to match existing devices, Pass & Seymour TradeMaster grounding toggle switches cover it: the 660G is brown satin thermoplastic and the 663LAG is light almond thermoplastic. Use those on the general lighting in the unit and reserve the Leviton pilot light device for the circuits that need visible status, such as a bath fan or a water heater disconnect.
7) What is the difference between industrial grade and specification grade toggle switches when I am standardizing a building?
The Leviton 1201-PLC and 1221-PLR are built to industrial grade and add a pilot light for circuit status. The Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle switch in ivory, and the Pass & Seymour PS20AC3W is an industrial extra heavy duty specification grade device in white. If a facility standard names specification grade on the drawing, the Pass & Seymour devices answer that call-out directly; the Leviton is the choice where you also want lit indication at the switch and an industrial grade device. Finish also differs - ivory on the CS20AC3I, white on the PS20AC3W.
8) Is the Pass & Seymour 660G a substitute for the Leviton pilot light switch?
Not a direct one. The 660G is a TradeMaster grounding toggle switch in brown satin thermoplastic - a standard switching device without an indicator. The Leviton 1201-PLC and 1221-PLR are industrial grade devices whose defining feature is the integrated pilot light behind a clear lens for at-a-glance circuit status. Swapping in the 660G changes the finish to brown and removes the status indication, which matters on any load the operator cannot see from the switch.
9) For a 20A commercial lighting circuit, how do the Leviton 1221-PLR and the Pass & Seymour CS20AC3I compare?
Both are 20A toggle switches for commercial work. The Leviton 1221-PLR is the 20A version of the industrial grade pilot light switch, 1-pole at 120V, with the lit indicator. The Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle switch supplied in ivory without an indicator. Pick on two points: whether the job spec calls industrial grade or specification grade, and whether the circuit needs visible status at the switch.
