Sourcing keyboards, including mechanical
The switch is the question everyone asks. The layout matrix is the one that decides whether the programme works.

The layout matrix, and what it costs
Physical layout differs by market, not just the printing. Between the common regional standards a key or two changes shape and position, so a keycap set is not a printing variation — it is a different set of mouldings, and the row profiles have to match.
Firmware layout is a separate axis again, and so is the operating-system convention the board is optimised for. A board sold for two platforms usually needs a switch, a key combination or two keycap variants, and every one of them is a support question if it is not documented.
Then multiply: markets × platforms × switch options × colourways. This is how a simple keyboard project becomes forty SKUs, and it is why the honest first decision is which markets you will actually serve at launch rather than which ones you would like to.
Ask the factory to separate the minimum order into its parts — the keycap tooling and minimum run, the case moulding, the electronics, the packaging print run — because they have different minimums and the keycaps or the packaging usually set the floor rather than the electronics. That conversation is where a small launch becomes possible.
And agree the tooling question before the money moves: who owns the keycap and case tools, where they are stored, and what happens if production moves.
Legends, keycaps and what wears out
How the legend is made is the whole durability question. Characters formed through the cap material survive as long as the cap does. Characters printed or lasered on the surface wear, and the wear starts on the keys the customer uses most, which is exactly where it is most visible.
So put it in the specification explicitly, and check it on the sample by abrading a key rather than by looking at it. This is invisible at purchase and obvious after a year, which makes it the single most common long-term complaint in the category.
Keycap material and profile. The plastic used affects how quickly caps become shiny under finger oils, and the profile decides how the board feels to type on. Both are specification lines, and both are visible in a photograph if you know what you are looking at.
Backlighting, if used. Whether legends are lit through the cap, whether the lighting is even across the board, and what happens to unlit legends in a dark room. Uneven backlighting is a manufacturing consistency issue and worth checking across several units rather than one.
Compatibility. If your customers may replace keycaps, the stem type and the row profile decide whether aftermarket sets fit — which for some markets is a selling point and for others is irrelevant. Decide deliberately.
The parts that decide how it feels
The plate and the mounting. What the switches are mounted to, and how that assembly is fixed in the case, decides the board's stiffness and much of its sound. Two boards with identical switches on different plates are different products.
Stabilisers. The long keys — space, shift, enter — need stabilisers, and rattling stabilisers are the most common complaint about an otherwise good keyboard. Ask what type is used, whether they are lubricated in the factory, and specify a rattle check as a line in the quality plan.
The switch itself. Specify the exact part from the switch maker rather than a colour name, because colour naming is not standardised across makers. Actuation force, travel and life figures belong to that maker's datasheet and are not restated here; ask for the datasheet and put the part number in the specification.
Case construction and feet. Flex, resonance, whether the feet hold on a desk and whether the hinge on adjustable feet survives. Feet are a cheap part with a high complaint rate.
Wireless variants add a radio and a battery: qualification with a Declaration ID against a member company, per-market radio approval, and the cell specification and its transport documentation. A wired board avoids all three, which is a real cost difference worth pricing.
Sampling and choosing the factory
Business licence and business scope (经营范围) first, then: who makes the keycaps, who makes the case, who writes the firmware, and can the firmware be changed for you? Keyboard assembly is frequently the only part done in-house, and the answer decides what you can customise.
Type on the samples for a week, several people, in the layout your market actually uses. Then test every key including the ones nobody presses, check for rattle on every long key, and check for consistency across several units — variation between units is the thing a single sample hides.
Abrade the legends. Test the feet. Test the cable or, on wireless, the reconnection behaviour after sleep, which is the most complained-about wireless keyboard behaviour there is.
Then take one apart: the plate material and thickness, how the assembly is mounted, the stabiliser type and whether they are lubricated, the controller and how the cable or radio is terminated.
Every supplier on this site is a manufacturer, and the registered-scope check is one of the things confirmed before a listing goes live.
Questions people actually ask
What is the hardest part of sourcing keyboards?
The layout matrix, not the switches. Each market needs its own keycap set with its own legends and its own firmware layout, and between common regional standards a key or two changes shape — so it is a different moulding, not a printing change. Markets multiplied by platforms, switch options and colourways is how a simple project becomes forty SKUs.
Why do keyboard legends wear off?
Because they were printed or lasered on the surface rather than formed through the cap material. Characters formed through the cap last as long as the cap; printed ones wear first on the most-used keys, which is where it shows most. It is a specification line, and you can check it on a sample by abrading a key.
Do switches decide how a keyboard feels?
Less than buyers expect. The plate the switches are mounted to, how that assembly is fixed in the case, the case construction and the stabilisers on the long keys decide most of the sound and feel. Two boards with identical switches on different plates are different products.
What causes keyboard rattle?
The stabilisers on the long keys — space, shift, enter. Rattling stabilisers are the most common complaint about an otherwise good keyboard. Ask which type is used and whether they are lubricated in the factory, and put a rattle check into the quality plan rather than discovering it in reviews.
How do I specify a switch properly?
By the exact part from the switch maker, not by a colour name — colour naming is not standardised between makers, so "brown" means different things. Ask for the maker's datasheet, put the part number in the specification, and take the force, travel and life figures from that datasheet rather than from a listing.
Is a wireless keyboard much more expensive to source?
It adds three things a wired board does not have: Bluetooth qualification with a Declaration ID, radio approval in each destination market, and a battery with its own specification and transport documentation. Those are real costs and a real timeline, so price and schedule them deliberately rather than treating wireless as a feature toggle.
