Pass & Seymour CSB20AC2 – Frequently Asked Questions

1) Will the CSB20AC2 fit a standard single-gang box and a standard wall plate?
Yes. The switch body measures 3.281 in high, 1.32 in wide and 1.073 in deep, which is the normal toggle switch strap and body footprint for a single-gang box and a standard toggle-opening wall plate. Mounting screws are tri-drive heads, so a flat blade, Phillips or square driver all work.
2) Is this switch listed for federal and institutional specification work?
The CSB20AC2 is Federal Spec Listed and cULus Listed. Those are the two listings called out on the device, which is what most government, healthcare and school specs ask for when they call for a specification grade AC toggle switch.
3) What else could I use instead of the Pass & Seymour CSB20AC2 if I need a 20A spec grade single-pole switch?
The closest cross-brand equivalents are the Leviton 1221, an extra heavy-duty industrial specification grade SPST switch rated 20A 120/277V, and the Leviton 1221-2KL spec grade 1-pole, also 20A 120/277V. Both sit in the same specification grade class as the Pass & Seymour. Bryant's 4801W is a lighter duty option at 15A 277V, so it is not a straight swap on a 20A circuit.
4) What is the closest equivalent to the Pass & Seymour CSB20AC2 20A toggle switch from another manufacturer?
The Leviton 1221 is the nearest match in function class: it is an SPST single-pole toggle switch rated extra heavy-duty industrial specification grade at 20A, 120/277V. Like the CSB20AC2, it is a single-pole 20A specification grade toggle, so it fits the same single-pole switch leg. The Leviton 1221-2KL is the same extra heavy-duty spec grade 1-pole 20A 120/277V device under a different catalog number. The CSB20AC2 comes in brown and, as CSB20AC2-I, in ivory, so confirm the device color you need against the Leviton catalog number you order.
5) What colors does the Pass & Seymour CSB20AC2 20A toggle switch come in?
Two colors: brown (CSB20AC2) and ivory (CSB20AC2-I). Both are the same 20A hard use specification grade switch in a matte thermoplastic housing, so you can match existing device colors across a floor without changing switch grade.
6) Why pay for a spec grade switch instead of a residential one in a school or office corridor?
Wear points are where cheap switches fail. The CSB20AC2 uses a one-piece brass alloy contact arm, oversized silver alloy contacts, heavy-duty toggle bumpers, and a glass-reinforced nylon back body with locking support that resists the face separating from the back body. In a corridor, restroom or shop floor that gets thrown dozens of times a day, those are the parts that decide whether you are back in the wall in a year.
7) Does a wall plate come with the CSB20AC2?
No plate is included. What you get is the switch with its tri-drive terminal and mounting screws, so add the wall plate separately and pick the plate color to match the brown or ivory device.
8) My fixtures run on a 277V lighting circuit - which of these switches can I use?
The Pass & Seymour CSB20AC2 is an AC specification grade switch rated 20A. Among the alternatives rated for 277V service, the Leviton 1221 and 1221-2KL are 20A 120/277V single-pole devices, the Leviton 1221-2L is a 20A 120/277V pilot light single-pole, the Eaton Arrow Hart three-way is 20A 120/277V, and the Bryant 4903 is a 20A 277V three-way. The Leviton 1201PLC is a 120V device and is not the one for a 277V lighting branch.
9) Is there a version with a pilot light so staff can see the switch is on from the corridor?
The Pass & Seymour CSB20AC2 is a plain hard use specification grade toggle with no indicator. For an illuminated indication, the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V, and the Leviton 1221-2L is an industrial grade pilot light toggle rated 120/277V AC, 20A, 1-pole. The 1221-2L matches the CSB20AC2's 20A single-pole configuration while adding the pilot; the 1201PLC is a 120V device.
10) Can I use the Bryant 4801W in place of the Pass & Seymour CSB20AC2?
Not as a direct swap on a 20A circuit. The Bryant 4801W is a 4-Series single-pole AC toggle switch rated 15A at 277V, while the Pass & Seymour CSB20AC2 is a 20A device. They share the single-pole toggle format, but if the branch circuit or the specification calls for a 20A rated switch, the 15A Bryant does not satisfy it. Use the 4801W only where a 15A single-pole switch is acceptable.
11) What is the difference between commercial grade and specification grade toggle switches when I am standardizing a building?
Grade describes the construction level. The Pass & Seymour CSB20AC2 is a hard use specification grade device with a one-piece brass alloy contact arm, oversized silver alloy contacts and a glass-reinforced nylon back body, and it carries Federal Spec and cULus listings. Among the alternatives, the Leviton 1221 and 1221-2KL are also specification grade, the Leviton 1201PLC and 1221-2L are industrial grade, the Eaton Arrow Hart three-way is industrial grade, and the Bryant 4903 is commercial grade. If your spec sheet calls out specification grade throughout, stay with the CSB20AC2 or the Leviton 1221 family.
12) Is the toggle handle on this Pass & Seymour switch going to snap off in a warehouse or shop?
The handle is high-strength thermoplastic polycarbonate, specified to resist breaking and chipping under heavy abuse, and it rides on heavy-duty bumpers for quieter travel and less internal wear. That is the reason this one is sold as a hard use device for industrial and manufacturing spaces rather than a standard commercial switch.
13) I need a white device to match the other plates on the floor - what are my options?
The Pass & Seymour CSB20AC2 is offered in brown and, as the CSB20AC2-I, in ivory. If white is required to match existing devices, the Bryant 4801W is a white single-pole 15A 277V toggle and the Bryant 4903W is a white 3-way 20A 277V commercial grade toggle. Check the rating you need before substituting on color alone, since the 4801W is a 15A device and the 4903W is a three-way.
