Read two listings for the HERO 84 HE and one may call its switches Black King while another says Black Emperor. That naturally raises a worry that two batches exist with different feel, or that one listing is simply wrong. The good news is simpler: this is a Black King magnetic switch with a second name, and AULA uses both for the same part.
Quick Answer
Yes, they are the same switch. On the AULA HERO 84 HE, Black King and Black Emperor are two names for one pre-lubed magnetic switch. It needs 33gf to actuate, reaches 53gf at the bottom and travels 3.4mm, and the board lets you set its actuation point anywhere from 0.1mm down that stroke. The HERO 84 HE itself is priced at R719 at Evetech.
🏷️ Where the two names come from
Switch makers and keyboard brands often translate or rebrand a part for different markets, and one design can collect two names that way. The product page for the HERO 84 HE settles it in plain terms: the switch is Black King, and AULA also calls it Black Emperor. Nothing on the page suggests a second version with different figures.
So if you see either name on a box, a review or a spec table, read it as the same component. The practical effect is mostly on searching, which we come back to below.
⚖️ What the figures tell you about the feel
Three numbers describe this switch, each with a small tolerance AULA publishes:
- Actuation force of 33gf, give or take 5gf. That is on the light side, so a resting finger can trip a key if you set a shallow actuation point.
- Bottom-out force of 53gf, give or take 5gf. The spring firms up as you push, so there is a clear floor under the press.
- Total travel of 3.4mm, give or take 0.1mm.
Because it is a Hall Effect design, the press is read by a sensor measuring the magnet's position rather than by metal contacts touching. That is why the actuation point is adjustable at all. On this board it moves in steps of 0.01mm between 0.1mm and 3.4mm, and with Rapid Trigger on, a key lets go as soon as your finger begins lifting.
What pre-lubed changes
Factory lubrication reduces the scratch of the stem sliding in its housing and softens the sound. It also means you do not have to open switches and lube them yourself to get a smooth stroke, which suits anyone who wants a finished board. The HERO 84 HE adds five layers of dampening inside the case, so the lubed switches are only part of the sound story.
🔍 Searching for spares or replacements
Because the board is hot-swappable, you may one day want to replace a switch or try a different one. Search with both names, since sellers are not consistent about which they list. Then check the part is a magnetic switch built for this kind of board.
AULA's partner store makes a point worth repeating: not every magnetic switch fits every magnetic keyboard. Stay within a compatible magnetic switch family, and treat any listing that does not state compatibility with caution. Evetech's keyboard switches category is a sensible place to compare options, but read each listing's compatibility note before assuming a fit.
The board does support mixed switch setups, so a few keys can carry a different switch while the rest keep their Black Kings. After any change, revisit the actuation settings in the web driver, since a new switch may call for a different point.
The HERO 84 HE itself is part of Evetech's gaming keyboards range, covered by a 2 Years Local Warranty. Its price is listed on the Evetech product page.
Frequently Asked Questions
Is Black Emperor a heavier or lighter version?
No. It is the same switch as Black King, with the same 33gf actuation and 53gf bottom-out figures.
How light is 33gf in practice?
It is a light press. Pair it with a slightly deeper actuation point in the driver if you find keys triggering when your fingers rest on them.
Do I need to lube these switches?
No. They come pre-lubed from the factory, so they are smooth out of the box.
Can I put a different magnetic switch in a few keys?
Yes, mixing is supported. Check that the replacement belongs to a compatible magnetic family before you pull anything.
Does the switch name change the actuation range?
No. Whichever name a listing uses, the board still tunes the switch between 0.1mm and 3.4mm, one hundredth of a millimetre at a time.
