Pass & Seymour CS20AC1-LA – Frequently Asked Questions

1) What wire size do the terminals on the Pass & Seymour CS20AC1LA switch accept?
Terminals on the CS20AC1LA take #14 through #10 AWG copper or copper-clad wire. You can side wire it, or use the external screw-pressure-plate back and side wire terminals, so it drops into a box where the existing conductors are already stripped and looped or where you want straight back wiring on a #12 branch circuit.
2) Is this Pass & Seymour switch UL listed and acceptable on a federal or government job?
The CS20AC1LA is cULus Listed and carries Federal Spec listing, which is what a government or institutional spec usually calls out for a specification grade wiring device. No other grade or standard is claimed on it.
3) What is the closest equivalent to the Pass & Seymour CS20AC1LA single-pole spec grade switch from another brand?
The Leviton 1221-2W is the nearest match: it is an extra heavy-duty industrial specification grade SPST single-pole toggle switch rated 20A at 120/277V AC. Like the CS20AC1LA, it is a specification grade toggle built for commercial and industrial wiring. The CS20AC1LA comes in Light Almond with a matte finish, so if color matching to existing Light Almond devices matters, confirm the Leviton color code before substituting.
4) What do I use instead of the Pass & Seymour CS20AC1LA for a motor or three-wire circuit that needs a center-off position?
The CS20AC1LA is a single-pole switch with simple on-off action. For a center-off application, the Leviton 1286-W is a 20A DPDT center-off toggle switch in industrial/specification grade, which gives you two independent positions plus a neutral middle. That is the device for reversing or two-source selection, not a single-pole switch.
5) Will the CS20AC1LA switch match light almond devices already in the building?
Light Almond with a matte finish is what the CS20AC1LA ships in, so it lines up with other light almond toggles and plates on a floor. Light almond and ivory are not the same shade, so if the other openings are ivory it will read off next to them.
6) Do I need a separate ground pigtail with the CS20AC1LA, or is the ground built in?
Grounding is through the one-piece steel strap with integral ground, plated for corrosion resistance. You bond to the strap's ground terminal; there is no separate grounding accessory involved.
7) What makes a specification grade switch like this worth it over a residential toggle in a high-traffic commercial space?
The pieces that wear out first are upgraded. The toggle is high strength thermoplastic polycarbonate so it resists breaking and chipping under abuse, the back body is glass-reinforced nylon with locking support to resist face and back body separation, and the contacts are oversized silver alloy on a one-piece brass alloy contact arm. The cam is built for a fast make with positive break to cut arcing. That is the difference in a corridor, restroom, or classroom switched dozens of times a day.
8) What are my alternatives if I need a locking toggle or a pilot light version instead of a plain spec grade switch?
Plain toggle is all the CS20AC1LA is. For a key or locking style action, the Leviton 1221-2IL is an industrial grade locking toggle, SPST 1-pole, 20A 120/277V, and the Bryant 4802L is a 4 Series single-pole locking AC switch at 20A 277V. If you need an indicator, the Bryant 4801GLI is a lighted AC switch, 20A 277V, and the Leviton 1223-PLR is a 3-way specification grade toggle with a pilot light at 20A 120V.
9) I need a switch and a receptacle in one gang. Can I use the Pass & Seymour CS20AC1LA?
No. The CS20AC1LA is a toggle switch only, with no receptacle on the face. For a combination device, the Eaton decorator duplex combination switch is a commercial grade 15A unit with auto-ground in white. Note the 15A rating and the white color if you are matching Light Almond devices elsewhere in the space.
10) Is the Bryant 9801 a drop-in replacement for the Pass & Seymour CS20AC1LA?
Not an exact one. The Bryant 9801 is a BR Series 1-pole AC switch rated 15A at 120/277V, so it is a lower ampere rating than a 20A spec grade device like the CS20AC1LA. It also accepts the same standard single-gang wall plate opening, so mechanically it fits, but if your drawing or panel schedule calls for a 20A switch, step up to a 20A device such as the Leviton 1221-2W instead.
11) For a facility standardizing on one spec grade switch, how does the Pass & Seymour CS20AC1LA compare with the Leviton 1221-2W?
Both are specification grade single-pole toggle switches suited to commercial and industrial lighting circuits. The CS20AC1LA is cULus Listed and Federal Spec Listed, with a glass-reinforced nylon back body, oversized silver alloy contacts, and side or back-and-side wire terminals accepting #14 to #10 AWG copper or copper-clad wire. The Leviton 1221-2W is described as extra heavy-duty industrial specification grade, rated 20A at 120/277V AC. Standardizing usually comes down to the wall plate color you have adopted across the building; the CS20AC1LA is Light Almond.
12) Does this switch make the loud snap that tenants complain about?
Heavy-duty toggle bumpers give the CS20AC1LA a smooth, quiet switching action, which is why it gets specified in offices, patient rooms, and hotel corridors where a hard snap draws complaints.
13) What are the dimensions of the CS20AC1LA switch body?
The device measures 3.281 in high, 1.32 in wide, and 1.073 in deep, which is standard strap-mount toggle geometry for a single-gang box and a standard toggle plate opening.
14) Where is the Pass & Seymour CS20AC1LA manufactured?
Mexico is the country of origin on the CS20AC1LA, which matters if your project has domestic-content or origin-disclosure requirements in the submittal package.
