Keycaps
Topre relies on polybutylene terephthalate (PBT) for the keycaps, which of course also underlines the premium claim in the end. This very special plastic is a very brittle material in itself, but it can withstand high temperatures, do not yellow or wears off slightly. The sublimation process ensures that the labels of the keycaps do not wear out so easily (compared to the tampon-printed ABS caps of the cheaper keyboards).
In this process, the key caps must withstand fairly high temperatures so that the paint can be transferred cleanly and completely from one material to the other, which is the case with other common plastics such as ABS is not possible. Dye-sublimated labels are also better than laser-engraved, etched, or mechanically engraved labels, as they are not so easily able to absorb dirt or dust, fade or detach when used.

Topre switch
The topre-buttons are basically hybrids, consisting of a Rubber dome, which sits under an upward conical coil spring. In addition to the very special click-feeling when triggering, the still audible, but also not too loud Plopp pleases during the complete pushing. The curve shows the whole thing very nicely and you just have to test it once to get excited about this type of switch. Tactile yes, but not loud or even strenuous with long-term use and many attacks.
And they are capacitive switches that have no mechanical contact surfaces. This also eliminates the logic required to underprint a possible bouncing, which manifests itself in multiple attacks. It also can't oxidize anything, which naturally increases the shelf life, which you can generously use up to 30 million. attacks.

Layout and modifications
Thus, the whole thing qualifies for real multi-writers via the buttons as such, but due to the layout is definitely not for gamers or colleagues, the Umlaute & Co. Need. Of course, you can use the function keys and third-party software to prove pretty much every button with everything, but then this is not really nice.
The rear dip switch is used for easy switching of the individual modes, whereby the HHK PC mode is preset by default.
We see from left to right the differences in direct comparison: HHK PC mode, Lite Extension mode and Macintosh mode.

Summary and conclusion
If you are looking for a very narrow but habitual and extremely minimalist keyboard of the highest production quality, the Happy Hacking Keyboard Professional 2 may even be in the right place – provided the purse is does not get a snapbreathing due to a lack of existing substance. For the rest, this keyboard is simply too special, even if the image and feel-good factor is definitely right when all customer profile requirements meet.
The keyboard is therefore what the "Black Afgano" from the project Nasomatto is among the good perfumes: an exotic, because one can love or hate, but does not have to understand in any way. Not cheap, but unusual and equipped with a certain will-will factor for the target group. However, the rest of the reader will just shake their heads and wonder if we are still doing well. The clear answer is yes.
