This was once supposed to be the top end HMKB brass plate. Unfortunately the switch cutouts ended up too tight. The issue was not discovered right after production and so the plates underwent two additional and costly steps. They got bead blasted and after that they went through a galvanizing process that applied a black zinc layer. This layer prevents the brass from tarnishing. On the renderings and photos they might look like the steel plates but in real life they do have a more premium appearance. They can not be sold as switch plate, not even as b-stock, since the cutouts are simply too tight to house switches without issues.

You could try and use a file to scratch a bit of material off from the switch housing, at the surfaces that snap into the plate but you would not be able to used the switches in other plates after that comfortable. These plates are explicitly not sold as keyboard switch plates.

However they do make a surprisingly practical paperweight. Whether placed on a small or big paper sheet stack the plate has well enough weight to keep them firmly in place. Since they are flat you can also use them like separators in a stack. By having multiple of these on or next to your desk can come in very handy, especially when you regularly rely on paper.

If you put two of them into the the shopping cart, one will automatically be free. So it's currently a 2 for 1 offer.


The powder coated steel cases are available in four colors. This coating is very durable and has a slightly grainy texture. A fifth version is made of stainless steel, it is bare metal with bead blasted finish.

- RAL 1013 oyster white, fine texture
- RAL 7039 quartz grey, fine texture
- RAL 9005 jet black, fine texture
- RAL 1023 traffic yellow, fine texture
- 304 stainless steel, bead blasted

RAL 1013 pairs well with old and classic cherry keycaps. RAL 7039 is a warm grey which is a perfect fit for dolch keycaps sets. RAL 9005 black goes well with almost everything. RAL 1023 is a vibrant yellow.

To represent the RAL colors in the renderings, the corresponding RGB values from this page were used. The colors on your specific monitor may appear different compared to the real life RAL colors.

Depending on the combination of your plate and pcb, many different key layouts can be built. To see exactly which key layouts you can build with your desired HMKB size and variant, please go to the layouts page to learn more.

For powder coating the parts are put on racks. This will leave a little mark. It is usually at one of the holes. Since the holes will be covered by the bolt heads, these marks will not be visible when the case is assembled. Although highly unlikely, it is possible that dust particles may be caught in the powder coating.

The bending process leaves slight marks. They are not a concern for the powder coated steel parts and not visible at all. The stainless steel parts are not powder coated but bead blasted instead. On all of the prototypes the bead blasting removed those marks completely and they were not present anymore. However, there is a small chance that some stainless steel parts may show slight traces of these marks, even after the bead blasting.

The angles of the flanges may not always be perfectly 90˚. Though unlikely, a deviation of up to 1˚ can occur. This would still be hardly noticeable.

The switch plates can have scratches. Do to the manufacturing process of sheetmetal, the switch plates may be slightly bent.

None of these effects are considered a defect and are no reason for a refund or a replacement.

PCBs need to be checked first before soldering. After soldering, damaged PCBs are not eligible for replacement.
