Decora and toggle are the two mechanical formats an American light switch can take: a wide flat paddle that rocks in a large rectangular opening, or a small lever that flips in a narrow slot. Decora is a Leviton trademark registered in 1975; the format itself is generic, sold by every manufacturer as a decorator or rocker device, and it now outnumbers the toggle in new American construction.
In short
- The decorator opening measures 1.31 in by 2.64 in. The toggle opening measures 0.40 in by 0.93 in. That is roughly nine times the area.
- DECORA was filed with the U.S. Patent and Trademark Office on 9 April 1974 and registered on 18 February 1975 under number 1,004,736, covering switches, receptacles and escutcheon plates.
- Specify the opening, not the brand: a plate cut for a decorator device fits a rocker, a GFCI receptacle, a USB receptacle and most smart dimmers.
- Studio Timeless builds the toggle as a complete solid brass unit, and builds the decorator format as a plate with empty openings for devices you supply.
- Our decorator plates run from $50 at 1 gang to $170 at 5 gangs, which puts the cheapest position on a 3-gang plate at $24.
What a Decora switch actually is
A Decora switch is a general-use snap switch whose actuator is a wide flat paddle that pivots at its centre, mounted behind a large rectangular plate opening. Mechanically it does the same job as a toggle: it makes and breaks a line conductor. Everything that differs sits above the yoke. The yoke, the strap, the mounting screw spacing at 3.281 in and the 6-32 thread are shared with the toggle, which is why a rocker and a lever interchange in the same wall box. You can read the rest of the box side of the question in our guide to what two-wire and three-wire cable allow.
The industry word for the shape is decorator. The industry word for the motion is rocker, and in commercial specifications paddle. Decora is one manufacturer's name for it, in the same family as Despard or Lev-Lok. We use decorator throughout this article when we mean the opening, and rocker when we mean the device, because that is the language a plate supplier can act on.
Where the name came from: a 1974 trademark and a 1970s line
The name Decora entered the American market as a Leviton trademark in the mid 1970s. The federal register records the application filed on 9 April 1974 and registration granted on 18 February 1975, registration number 1,004,736, for electrical wiring devices, namely switches, receptacles and escutcheon plates. The mark has been renewed and is still live. Leviton's own corporate history places the launch of the Decora designer line in the 1970s and describes it as a benchmark for modern rocker switches and outlets.
That timing matters for anyone restoring a house. A rocker switch is not a period detail in anything built before about 1975. If you are specifying for a house from the 1920s or the 1950s, the push button and the toggle are the honest formats, and our notes on mid-century electrical hardware set out what a 1955 wall actually carried.
Why decorator and rocker are the words to put on a list
Write decorator or rocker on your plate order, never Decora, because a brand name tells a machinist nothing about a cut. Orders reach us asking for a Decora plate when the customer meant a blank plate, and the inverse. The opening families we machine are distinct and not interchangeable after the fact: toggle slot, rotary dimmer bore, decorator rectangle, duplex figure-of-eight, and blank. A plate already cut for a rotary dimmer cannot be reworked into a toggle plate, and vice versa.
If you are specifying several formats across one wall, the combination plate guide explains how the five opening families pair up on a single piece, and the combination plates collection shows the pairings we hold.
The dimensional difference, in inches
The decorator opening is about nine times the area of a toggle opening, and that single fact drives most of the visual difference between the two formats. Manufacturer wallplate dimensional data gives the toggle opening as 0.40 in by 0.93 in and the decorator or GFCI opening as 1.31 in by 2.64 in. Multiplied out, that is 0.37 square inches of hole against 3.46 square inches. The standard plate around them is the same height in both cases.
| Measure | Toggle format | Decorator format |
|---|---|---|
| Plate opening | 0.40 in x 0.93 in | 1.31 in x 2.64 in |
| Open area | 0.37 sq in | 3.46 sq in |
| Industry standard plate height | 4.50 in | 4.50 in |
| Standard plate width, 1 to 5 gang | 2.75 / 4.56 / 6.37 / 8.19 / 10.00 in | 2.75 / 4.56 / 6.37 / 8.19 / 10.00 in |
| Device families it accepts | Toggle snap switch only | Rocker switch, GFCI, USB receptacle, most smart dimmers |
| Screws needed | Two per gang | Two per gang |
| What Studio Timeless supplies | Complete solid brass unit, switch machined into the plate | Solid brass plate with empty openings, device supplied by you |
Our own plates sit slightly outside the industry rectangle. A Studio Timeless 2-gang plate measures 4.56 in wide by 4.70 in high by 0.080 in thick, so it is 0.20 in taller than a standard 4.50 in plate. That extra height covers more of a ragged opening, which is useful on plaster walls, and it means a stock plastic plate on the next box along will not line up with ours. Plan to change plates in whole sight lines rather than one at a time. The full dimensional picture is in our plate sizing and gangs guide.
Why the decorator opening became the American default
The decorator opening won new construction because it accepts more device types than the toggle slot does, not because builders preferred the look. A GFCI receptacle needs the large rectangle. So does a tamper-resistant USB receptacle, a combination switch and receptacle, an occupancy sensor, a timer and almost every smart dimmer sold in the United States. Cut a box opening for decorator and you have kept every future option open. Cut it for a toggle and you have committed that position to one family of device forever.
It compounds: once a builder standardises on one plate, every position becomes a decorator position whether it needs to or not. Our GFCI installation guide covers where code actually requires the device, and the Brass GFCI Electrical Outlet is our own integrated answer for those positions.
What the toggle format kept
The toggle survived because the small opening reads as hardware rather than as equipment, and because the lever gives a definite mechanical report at the moment of switching. On a solid brass plate the difference is pronounced: with only 0.37 square inches of hole, the eye reads a machined metal surface with a small lever on it. With 3.46 square inches of hole, the eye reads a frame around a plastic device. That is why a brass toggle sits comfortably in a panelled hallway and a brass frame around a white rocker often does not.
Our two lever ranges answer different periods. The knurled toggle takes the standard American rectangular cutout. The Retro Toggle requires a 12 mm round opening and is a different cut entirely. The differences are set out in Knurled vs Retro Toggle, and both ranges are in the brass light switches collection. One point of accuracy on certification: the Retro Toggle carries a CE mark, not a UL or ETL listing, and we do not claim otherwise.
The accessibility argument, read against the actual standard
Neither format is disqualified by the ADA Standards, and the common claim that toggles fail accessibility requirements is not supported by the text. Section 309.4 requires that operable parts be usable with one hand, without tight grasping, pinching or twisting of the wrist, and with no more than 5 pounds of force. The U.S. Access Board guidance on operable parts lists flip switches among the acceptable control types, alongside lever handles and raised buttons, and reserves its objection for controls that demand wrist rotation.
Where the rocker has a genuine advantage is target size. A paddle can be operated with a forearm, an elbow or a closed fist; a lever generally wants fingers. If you are specifying for someone with limited hand function, that is a real reason to choose the rocker, and it is a stronger argument than the force threshold. The same reach range applies either way: 15 in to 48 in above the floor for operable parts.
Three-way, four-way and dimming do not change with the format
Switching function is a property of the device inside the wall, not of the shape you touch, so a rocker and a toggle can both be single pole, three-way or four-way. A three-way rocker and a three-way toggle wire identically: common, two travellers, and the same requirement for a three-conductor cable between the two locations. Our wiring guide covers single pole, three-way and four-way in full.
Dimming is where the formats separate in practice rather than in principle. Most American rocker dimmers are slide or tap devices sized for the decorator opening. Our dimming is rotary, with its own round bore, and is covered in the rotary dimmer guide; the dimmer collection holds 1 through 5 gangs. Two constraints hold whatever the format: only one TRIAC dimmer belongs on a given circuit, with any second location taken by a three-way toggle, and a 0-10V controller never interrupts the 120V line, so it always needs a separate switch and is incompatible with TRIAC.
The five-gang ceiling, and what a format war looks like on a wide wall
Five gangs is the widest plate we machine, which sets a hard limit on how many positions one opening can carry. A 5-gang standard plate is 10.00 in wide. Past that, a wall needs two plates side by side, and the format decision becomes visible: two 3-gang decorator plates read as a utility bank, while a 3-gang toggle plate beside a 2-gang toggle plate reads as hardware. Our 5-Gang Solid Brass Decorator Wall Plate and 4-Gang Solid Brass Decorator Wall Plate are the two widest in that family.
Remember the screw count when you price a wide wall: two screws per gang, not two per plate. A 5-gang plate takes ten screws. Longer fixings are in brass screws and extensions.
What Studio Timeless makes in each format, and what it does not
We make complete units in the toggle and rotary formats, and plates only in the decorator format. This is the single most important thing to understand before ordering, and it is the reverse of the usual American convention. A Studio Timeless toggle switch is one machined piece: the switch is built into its solid brass plate, so there is no seam between a plate and a device. A Studio Timeless decorator plate is a plate with empty rectangular openings and no mechanism supplied, intended to dress a rocker, GFCI or USB device that you or your electrician provide.
We do not make a brass rocker. If you want a flat paddle, you buy the device elsewhere and we supply the plate around it. That is an honest limit, and it is also why the decorator plates exist in the range at all: they let a house keep its code-driven decorator positions while still changing every visible surface to solid brass. The whole plate family is in wall plates and outlet covers, with outlet plates, toggle switch plates, dimmer switch plates and blank plates split out by opening.
The cost of a position, format by format
The cheapest decorator position in our range is on a 3-gang plate, at $24 per opening, and the most expensive is on a 1-gang plate, at $50. The curve is not linear, because a 3-gang plate carries the same list price as a 2-gang plate before the price steps up at 4 gangs. Prices below are current catalogue list in the lacquered stock finishes; Unlacquered Antique Brass runs a few dollars higher, is made to order with a longer lead time, and is not returnable.
| Plate | List price | Openings | Cost per position |
|---|---|---|---|
| 1-Gang Brass Decorator Wall Plate | $50 to $55 | 1 | $50.00 to $55.00 |
| 2-Gang Brass Decorator Wall Plate | $72 to $77 | 2 | $36.00 to $38.50 |
| 3-Gang Decorator Wall Plate | $72 to $77 | 3 | $24.00 to $25.67 |
| 4-Gang Decorator Wall Plate | $140 | 4 | $35.00 |
| 5-Gang Decorator Wall Plate | $170 | 5 | $34.00 |
| 1-Gang Solid Brass Toggle Wall Plate | $60 to $65 | 1 | $60.00 to $65.00 |
Two practical conclusions follow. If an electrician can gang three decorator positions into one box, the plate cost per position falls by half against three singles. And a 1-gang decorator plate is $10 cheaper than a 1-gang toggle plate, so the format choice at a single position is not a money decision.
What one real whole-house order chose
On a solid brass order we built in September 2026 covering fourteen zones of one house, 55 of the 88 plates were decorator plates and only 33 carried our own switches. Counted by position rather than by plate, 57 of the 154 gangs were empty decorator openings and 97 carried a Studio Timeless control: 52 single-pole rotary dimmers, 17 three-way rotary dimmers, 22 single-pole or three-way knurled toggles, 4 four-way toggles and 2 fan speed controls. The order listed at $13,815 before any trade discount.
| Count | Plates | Gangs | Share of gangs |
|---|---|---|---|
| Decorator plates, no device supplied | 55 | 57 | 37% |
| Plates with a Studio Timeless control | 33 | 97 | 63% |
| Total | 88 | 154 | 100% |
The lesson is about where the plates go, not about taste. Decorator positions cluster on receptacles and on utility devices, so they fall low on the wall and in service rooms, while the control positions cluster at door height where people look. A house can be two thirds decorator by plate count and still read entirely as a toggle house.
Mixing the two formats without it looking accidental
Mix formats by function and by height, not by room, so that the pattern is legible rather than random. The rule that holds up on site is simple: controls at switch height take the lever, service devices near the floor and behind counters take the decorator opening. A single sight line should not contain a brass toggle and a brass-framed rocker doing the same job, because that reads as a supply problem.
Where a wall genuinely needs both on one plate, specify a combination piece rather than two plates. Our 2-Gang Brass Dimmer and Outlet Wall Plate pairs a rotary bore with a decorator rectangle on one piece, which is cleaner than a dimmer plate beside a decorator plate. The broader style question is covered in what is in style in 2026 and in toggle vs rocker.
Finish behaviour: the device you buy elsewhere will not match
A solid brass plate and a mass-market plastic rocker will never read as one object, because one is machined metal and the other is moulded thermoplastic. That is not a defect but a consequence of sourcing the device separately, so choose its colour deliberately. White and light almond rockers read as deliberate inserts behind brass. Grey and ivory rarely do.
Our Matte Black and White plates offer a controls finish option, Matching, Brass Accents or Stainless Accents, which is how the screws and visible accents are handled. On the brass finishes the screws come matched by default. The full comparison of the eight finish names is in all eight finishes side by side, and the Finish Sample Set at $50 is the way to settle it in hand before a whole house is committed. If you are drawn to the living finish, read unlacquered brass first: it is made to order, slower, and not returnable.
What to write on the electrician's list
Give your electrician the format and the function for every position, in that order, because that is what determines both the box and the plate. A workable line looks like this: kitchen, 4-gang, position 1 rotary dimmer three-way, position 2 rotary dimmer single pole, position 3 decorator opening, position 4 decorator opening. Without that mapping we will still build the pieces, but the modules will have to be swapped on site to match each circuit.
Before any device is touched, switch off the breaker and verify the absence of voltage at the conductors with a tester you have proved on a known live circuit. Work to the edition of the National Electrical Code adopted where you live, confirmed with your local authority having jurisdiction; the current edition is published by the NFPA as NFPA 70. A licensed electrician and a permit are generally required for new or relocated boxes, new circuits, panel work, anything in a kitchen or bathroom in many jurisdictions, and any rental or multi-family property. Our installation and compatibility page is the reference for wiring questions, and we do not confirm a wiring compatibility without written confirmation from the manufacturer. Designers and builders specifying across several projects can apply to the trade program, and bespoke configurations go through the Custom Configurator.
Frequently asked questions
What is a Decora switch?
A Decora switch is a rocker or paddle switch sized for the large rectangular decorator opening of 1.31 in by 2.64 in. Decora is a Leviton trademark registered in 1975; the generic terms are decorator and rocker.
What is the difference between a Decora switch and a toggle?
The internal switching is the same. The difference is the actuator and the hole it needs: a wide paddle in a 1.31 in by 2.64 in opening, against a small lever in a 0.40 in by 0.93 in slot, which is about nine times less open area.
Is Decora better than a standard switch?
Neither is better mechanically. The decorator opening accepts more device types, including GFCI, USB and most smart dimmers, so it is more future-proof. The toggle reads as hardware rather than equipment, which is why it suits a brass plate.
What is a rocker light switch?
A rocker light switch is one whose actuator pivots at its centre so that one end goes in as the other comes out. Paddle and decorator are the other common names for the same thing.
What is a 3-way rocker switch?
It is a rocker-format switch with a common terminal and two travellers, used so that two switches control one light. Three-way is a function of the device, not of the format, so three-way rockers and three-way toggles wire the same way and need a three-conductor cable between locations.
Can I put a Decora device in a toggle plate?
No. The openings are different sizes and cannot be converted. A plate machined for a toggle slot will not accept a rocker, and a decorator plate will not frame a toggle neatly.
Does Studio Timeless make a brass rocker switch?
No. We make complete solid brass units in the toggle and rotary dimmer formats, and we make solid brass decorator plates with empty openings for rocker, GFCI or USB devices that you supply.
Do your decorator plates come with a switch?
No. A decorator plate is supplied as a plate with empty rectangular openings and no mechanism. Our toggle and rotary pieces are the opposite: a single integrated unit with the control machined into the plate.
How many gangs can a decorator plate have?
We machine 1 through 5 gangs. A 5-gang standard plate is 10.00 in wide and takes ten screws, because the count is two screws per gang rather than two per plate.
Are rocker switches required for accessibility?
No. ADA Standards section 309.4 asks that operable parts need no tight grasping, pinching or twisting and no more than 5 pounds of force, and Access Board guidance lists flip switches as acceptable. The rocker's real advantage is a larger target that can be worked with a forearm or elbow.
Why does a 3-gang decorator plate cost the same as a 2-gang?
That is how the current catalogue is priced: both list at $72 to $77, with the step up coming at 4 gangs. It makes the 3-gang plate the cheapest position in the range at $24 per opening.
Which format should I use in a period house?
The toggle, or a push button, for anything built before the mid 1970s, since the decorator format only reached the market in that decade. Keep decorator openings for receptacles and service devices, where code and device availability push you there anyway.
Specifying it
Format is a decision about openings, and openings are permanent in a way that devices are not. Choose the lever where people look and the decorator rectangle where devices have to go, then put both on one piece wherever a wall will take it. Start with the switches and outlets collection or the wall plates collection, and send drawings or photos through contact if a wall is unusual.
