Pass & Seymour CS20AC1W Commercial Specification Grade Toggle Switch, White

The Pass & Seymour CS20AC1W is a Commercial Specification Grade toggle switch finished in White, engineered for demanding professional and commercial electrical installations. This switch pairs a one-piece steel strap with integral ground, plated for corrosion resistance, with a high strength thermoplastic polycarbonate toggle that resists breaking and chipping under heavy daily abuse. It accepts #14 - #10 AWG copper or copper-clad wire through side wire or external screw-pressure-plate back connections, and is backed by both Federal Spec Listed and cULus Listed ratings for dependable, code-compliant performance where reliability is non-negotiable.

Key Features

  • Corrosion-Resistant Strap: One-piece steel strap with integral ground is plated for long-term corrosion resistance.
  • Durable Toggle: High strength thermoplastic polycarbonate toggle resists breaking and chipping under heavy abuse.
  • Quiet Operation: Heavy-duty toggle bumpers deliver smooth, quiet switching action.
  • Reinforced Back Body: Glass-reinforced nylon back body with locking support resists face and back body separation.
  • Reliable Contact Arm: One-piece brass alloy contact arm ensures consistent electrical performance.
  • Secure Terminations: Tri-drive terminal and mounting screws simplify installation and improve holding strength.
  • Long Switch Life: Cam is designed for fast make with positive break action to minimize arcing and prolong switch life.
  • Flexible Wiring: Side wire or external screw-pressure-plate back accepts #14 - #10 AWG copper or copper-clad wire.
  • Oversized Contacts: Oversized silver alloy contacts provide longer, more dependable switch life.

Pass & Seymour CS20AC1 – Frequently Asked Questions

1) What wire size does the Pass & Seymour CS20AC1 toggle switch accept, and can I back-wire it?
The CS20AC1 takes #14 through #10 AWG copper or copper-clad wire. You can side wire it at the screw terminals or use the external screw-pressure-plate back connection, so it suits both pigtail side-wiring and straight back-wired runs where #10 would be awkward to loop around a screw. Tri-drive terminal and mounting screws let you drive them with the bit you already have on the belt.
2) Is the Pass & Seymour CS20AC1 switch acceptable for a federal or government job spec?
It is Federal Spec Listed and cULus Listed, which is what specifiers on government and institutional work usually ask for on a wiring device. That pairing is also what lets it stand in on commercial spec-grade upgrades where an inspector wants a recognized listing on the device itself.
3) I need a three-way switch instead of the Pass & Seymour CS20AC1 - what should I order?
The CS20AC1 is a single-pole commercial specification grade toggle switch, so for three-way switching at a pair of openings use a dedicated 3-way device. The Bryant 4903W is a 3-way AC toggle switch rated 20A at 277V in commercial grade, and the Eaton Arrow Hart 1223GY is an industrial grade three-way toggle switch rated 20A at 120/277V in gray. Both control one load from two locations, which a single-pole device cannot do regardless of how it is wired.
4) I need the switch to show when the load is energized - does the Pass & Seymour CS20AC1 do that?
The CS20AC1 is a standard commercial specification grade toggle with a thermoplastic polycarbonate toggle and no indicator. For a visual on/off or load-energized indication, use a pilot light device instead: 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 switch rated 20A at 120/277V AC, 1-pole. Pilot light devices typically require a neutral in the box, so verify the wiring at the opening.
5) What is the closest spec grade equivalent to the Pass & Seymour CS20AC1 single-pole toggle switch?
The Leviton 1221 is the nearest match. It is an SPST extra heavy-duty industrial specification grade toggle switch rated 20A at 120/277V, which puts it in the same specification-grade class as the CS20AC1. The Pass & Seymour unit terminates #14 to #10 AWG copper or copper-clad wire by side wire or external screw-pressure-plate back wiring and is cULus Listed and Federal Spec Listed. If you want the same Leviton device with a locking lever, the 1221-2KL is the extra heavy-duty spec grade 1-pole version rated 20A, 120/277V.
6) What colors does the Pass & Seymour CS20AC1 commercial toggle switch come in?
Two: brown (CS20AC1) and white (CS20AC1-W). Both are a matte finish, so they read flat rather than glossy next to existing matte devices and plates on the rest of your openings.
7) Will a commercial spec grade switch hold up in a high traffic area where residential switches keep failing?
That is what this one is built for. The toggle is high strength thermoplastic polycarbonate that resists breaking and chipping, the back body is glass-reinforced nylon with locking support to stop face-to-back separation, and the contacts are oversized silver alloy on a one-piece brass alloy contact arm. The cam gives a fast make with positive break to cut arcing, which is the usual failure mode on switches cycled hundreds of times a day in offices, retail, and corridors.
8) Does the CS20AC1 switch need a separate ground pigtail to the box?
No separate grounding clip is needed on the device itself. The CS20AC1 uses a one-piece steel strap with integral ground, plated for corrosion resistance, so the yoke grounds through the mounting screws to a properly grounded metal box. Run a bonding conductor to the box per code as usual.
9) What is a comparable spec grade single pole toggle switch from another brand?
Leviton's 1221 SPST extra heavy-duty industrial specification grade toggle, 20A 120/277V, is the closest cross-brand equivalent we stock, and the 1221-2KL is the same extra heavy-duty spec grade 1-pole device at 20A 120/277V. If you want a lower-amperage single-pole instead, the Bryant 4801W 4-Series is 15A 277V.
10) Is there a 15 amp alternative if the Pass & Seymour CS20AC1 is more switch than my circuit needs?
Yes. The Bryant 4801W is a 4-Series single-pole 15A 277V AC toggle switch in white, which suits a 15A lighting branch circuit where the 20A rating of the CS20AC1 is not required by the drawing. Note the Bryant device is 277V and single-pole only; confirm the circuit voltage before substituting.
11) Can I use an Ideal 774005 heavy-duty toggle switch in place of the Pass & Seymour CS20AC1?
Not as a direct swap in a wall box. The Ideal Industries 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, which is a panel or equipment-mount style device. The Pass & Seymour CS20AC1 is a single-pole commercial specification grade wall switch with a steel strap and integral ground, side wire or external screw-pressure-plate back connections for #14 to #10 AWG copper, and standard strap mounting for a device box and wall plate. Use the Ideal device for equipment switching and the CS20AC1 where a yoke-mounted wall switch is called for.
12) Where is the Pass & Seymour CS20AC1 switch made?
Mexico. That matters on jobs with domestic-content or country-of-origin reporting requirements, so it is worth noting on the submittal alongside its Federal Spec and cULus listings.
