Description
This 1-gang solid brass knurled rotary dimmer is designed to deliver smooth, reliable lighting control with a refined, premium feel in everyday use. When paired with compatible dimmable LED bulbs or TRIAC (leading-edge) drivers, it provides a clean dimming range with precise, responsive adjustment.
The knurled brass knob has a substantial weight and turns with accuracy, offering fine control without any loose or “plastic” sensation.
The 3 Way / Single Pole (universal) dimmer module is cULus listed (UL file E522988) for use in the United States and Canada. The Single Pole dimmer module is UL listed.
About Unlacquered Antique Brass: this is a handmade finish, made to order. Each piece is hand brushed, then oxidized by hand, so no two pieces are exactly alike and the brass keeps developing a natural patina over time. Current lead time for this finish: about 3 weeks of production before shipping.

Before You Buy
This dimmer uses TRIAC (leading-edge) technology, compatible with most dimmable LED and incandescent bulbs. Always verify your bulb or driver is labeled TRIAC / leading-edge compatible before ordering.
Not compatible with: trailing-edge (ELV), 0–10V, DALI, magnetic low-voltage, or smart bulbs.
If replacing an existing dimmer, confirm whether your setup requires single-pole or 3-way wiring.
Use dimmable bulbs only — incompatible LEDs may flicker, buzz, or have a limited dimming range.

Finishes & Natural Variations
Our wall plates are crafted from solid brass and finished entirely by hand. This process gives each piece a deeper, more refined look than plated alternatives, while naturally allowing for subtle variations from one item to another.
Aged Bronze (Hand-Brushed) — a rich, deep tone with a soft, greenish patina. The hand-brushed process ensures that every piece has its own unique character.
Antique Brass (Hand-Brushed) — an artisanal brushed finish with intentional variation. These differences are part of the design language, not imperfections.
Unlacquered Antique Brass (Hand-Brushed) — a living finish with no protective coating. Delivered with an aged appearance, it will continue to evolve over time as it reacts to air, touch, and its environment.
Satin Brass — a smooth brushed finish sealed with a protective lacquer. It maintains its original tone and slows down natural aging.
Stainless Steel — a clean, cool metallic finish with a refined brushed texture.
Matte Black — a solid brass base coated in a deep matte black for a bold, architectural presence.
White — a clean, minimalist coating over solid brass for a crisp, understated look.
Batch variation & hand-finishing notes:
Because each plate is finished by hand, slight differences in tone and patina between batches are expected. Factors such as brushing pressure, polishing, paint mixing, and even humidity can influence the final appearance.
Most finishes may vary by up to approximately 10% between batches.
For Unlacquered Antique Brass, a distinct oxidizing process is used. As a result, variations can be more pronounced, sometimes reaching up to 30% lighter or darker tones.
To ensure consistency, we make every effort to ship items from the same production batch whenever possible.
These natural variations are an inherent characteristic of genuine brass and are not considered defects.

| Plastic you touch | None | Often, around the dimmer | All of it |
| Weight | About 215 g (7.6 oz) | Lighter | Featherweight |
| The feel | Weighted, precise turn | Softer, lighter action | Hollow |
| Over the years | Ages beautifully, nothing to peel | Plating can wear through | Yellows and scratches |
| Made | Finished by hand | Mass produced | Mass produced |
How it's made
Made by hand, one piece at a time
Each plate is cut from solid brass and the knob is solid brass too. There is no plastic frame and no second face plate: the plate is one plain, smooth piece, so your wall reads as a single detail rather than a gadget.
Every piece is then finished by hand, brushed, aged or polished one at a time, and checked before it leaves the workshop. That is why no two plates are exactly alike, and why it feels so different the first time you reach for it.
