Pass & Seymour CS20AC3I Commercial 20A Specification Grade Toggle Switch, Ivory

The Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle switch finished in ivory, built for demanding electrical installations that require dependable, code-compliant switching. It features a one-piece brass alloy contact arm and oversized silver alloy contacts for long, reliable switch life, and it accepts side wire or external screw-pressure-plate wiring for #14 - #10 AWG copper or copper-clad wire. The switch is cULus Listed, giving specifiers and installers confidence in its safety and performance for commercial-grade projects.

Key Features

  • Amperage Rating: 20A specification grade toggle switch suited for commercial electrical loads.
  • Fast-Make Cam Action: Cam designed for fast make with positive break action to minimize arcing and prolong switch life.
  • Durable Contact Arm: One-piece brass alloy contact arm delivers reliable electrical performance switch after switch.
  • Oversized Contacts: Oversized silver alloy contacts extend dependable switch life under repeated cycling.
  • Heavy-Duty Toggle: Heavy-duty toggle bumpers provide smooth, quiet operation, and the high-strength thermoplastic polycarbonate toggle resists breaking and chipping under heavy abuse.
  • Reinforced Back Body: Back body made of glass-reinforced nylon with locking support that resists face and back body separation.
  • Wiring Flexibility: Available with side wire or external screw-pressure-plate back and side wire terminations capable of accepting #14 - #10 AWG copper or copper-clad wire, secured with tri-drive terminal and mounting screws.
  • Corrosion-Resistant Strap: One-piece steel strap with integral ground is plated for corrosion resistance.

Pass & Seymour CS20AC3-I – Frequently Asked Questions

1) What wire size does the Pass & Seymour CS20AC3I toggle switch accept?
The CS20AC3I takes #14 through #10 AWG copper or copper-clad wire. Terminations are side wire or external screw-pressure-plate back and side wire, held with tri-drive terminal screws, so you can land a #12 branch circuit conductor under the pressure plate rather than looping it on the screw. Aluminum conductors are outside what the switch is rated for.
2) Will a 20A switch like the CS20AC3I pass inspection on a commercial job?
It is cULus Listed and built to specification grade, which is the tier most commercial specs call out for switching. The 20A rating covers general-purpose lighting and receptacle circuit control on 20A branch circuits, and specification grade construction is what separates it from residential grade devices on a spec-driven project.
3) What is the closest equivalent to the Pass & Seymour CS20AC3I from another manufacturer?
The Pass & Seymour CS20AC3I is a 20A specification grade toggle switch. The closest cross-brand match is the Leviton 1221, an SPST extra heavy-duty industrial specification grade toggle switch rated 20A, 120/277V. Both are single-pole 20A spec grade devices, so the Leviton covers the same single-pole switching duty where a Pass & Seymour device is not on hand. The CS20AC3I is ivory; confirm the Leviton color matches the rest of the devices on the job.
4) Can I use the Ideal 774005 toggle switch in place of the Pass & Seymour CS20AC3I in a wall box?
No - they are different device types. The Pass & Seymour CS20AC3I is a specification grade wall-box toggle switch with a one-piece steel strap with integral ground and side wire or screw-pressure-plate terminals for #14 to #10 AWG copper. The Ideal Industries 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, intended for equipment and machine wiring rather than standard wall-box device mounting. For a wall switch replacement, stay with a yoke-mounted spec grade device.
5) Will this ivory switch match the ivory devices already in my building?
The CS20AC3I is ivory with a matte finish, so it reads the same as standard ivory wiring devices and ivory wall plates rather than the glossier older ivory. If your other openings are white or light almond, this will not blend; order the matching color for those locations instead.
6) Does the CS20AC3I need a separate grounding screw or pigtail?
No separate ground accessory is needed. The switch uses a one-piece steel strap with an integral ground, plated for corrosion resistance, so the equipment ground bonds through the strap and mounting screws. That plating matters in damp or chemically aggressive spaces like garages, kitchens and plant areas.
7) How well does this toggle switch hold up in a high-traffic space like a school corridor or lobby?
The wear parts are what to look at. A one-piece brass alloy contact arm and oversized silver alloy contacts carry the switching, the cam is built for fast make and positive break to cut arcing, and heavy-duty toggle bumpers keep the action quiet. The toggle itself is high-strength thermoplastic polycarbonate so it resists chipping and snapping under abuse, and the back body is glass-reinforced nylon with locking support that resists face-to-body separation, which is the usual failure when someone yanks on the device.
8) Can I use this switch to control a piece of equipment that needs two legs broken at once?
No. The CS20AC3I switches a single circuit and will not open both legs of a two-wire 240V or two-phase load. For that you need a double-pole device, such as the Ideal Industries 774005 heavy-duty DPST on-off toggle switch with spade terminals, though note that one uses spade terminals rather than screw terminations.
9) For a hospital or school standardization program, which 20A toggle switches are interchangeable with the Pass & Seymour CS20AC3I?
The CS20AC3I is a 20A specification grade, cULus Listed single-pole toggle switch. For single-pole locations, the Leviton 1221 and Leviton 1221-2KL are both 20A 120/277V specification grade single-pole toggles. For three-way locations in the same program, the Eaton Arrow Hart industrial grade three-way, 20A 120/277V, and the Bryant 4903W 3-way 20A 277V commercial grade cover those openings. Specify one color family across the facility, since the Pass & Seymour device is ivory.
10) I want a switch with a pilot light so housekeeping can see when a remote fixture is on - what replaces the CS20AC3I?
The Pass & Seymour CS20AC3I is a plain 20A specification grade toggle with no indicator. For an illuminated indicator, use the Leviton 1221-2L industrial grade pilot light toggle switch, 120/277V AC, 20A, 1-pole, which keeps the same 20A single-pole switching. The Leviton 1201PLC is also a pilot light toggle switch, 1-pole, 120V, if the circuit is 120V only.
11) What part number do I order for the ivory version, and where is it made?
Order Pass & Seymour CS20AC3-I for the ivory 20A specification grade toggle switch. It is manufactured in Mexico.
12) What is the difference between specification grade switches like the CS20AC3I and industrial grade switches?
The Pass & Seymour CS20AC3I is listed as specification grade, as are the Leviton 1221 and 1221-2KL, which are described as extra heavy-duty industrial specification grade. The Eaton Arrow Hart 20A three-way and the Leviton 1221-2L are industrial grade, and the Bryant 4903W is commercial grade. The grade wording reflects each maker's own construction tier; on the Pass & Seymour device that construction includes a one-piece brass alloy contact arm, oversized silver alloy contacts, and a glass-reinforced nylon back body. Match the grade called out on the drawing rather than assuming the labels line up across brands.
