A hot-swappable keyboard lets you pull a key switch out of its socket and push a different one in, with no soldering. That is the whole feature. You need it if you want to change how the keyboard feels or sounds later, or fix one dead key without sending the board away. If you will never change a switch, you do not need it.

The rest of this page covers how it works, what the label does not promise, and how to check a board before you buy.

What does hot-swappable mean on a keyboard?

On an ordinary mechanical keyboard, every switch is soldered to the circuit board. Corsair’s explainer on hot-swap keyboards puts it plainly: to replace a soldered switch you first have to desolder its pins, which takes far longer, and Corsair says it is not uncommon to break switches or damage the circuit board.

A hot-swap board uses a different circuit board. Instead of plain holes, each switch position has a small socket that grips the pins and carries the signal. Corsair notes that this makes the board more complicated and more expensive to build, which is why hot-swap keyboards often cost more. In practice, you pull a keycap off, grip the switch with a puller, and lift it out.

How a hot-swap switch change works, step by step

• Turn the keyboard off or unplug it.
• Pull the keycap off the switch you want to change. A keycap puller does this without bending anything.
• Grip the switch with a switch puller and pull it straight up.
• Line the new switch’s pins up with the socket and push it straight down until it clicks into place.
• Put the keycap back and test the key. If it does not register, check for a bent pin.

Many makers put a puller in the box. Epomaker lists a 2-in-1 switch and keycap puller with its TH65, for example. Do the first swap on a spare key, such as the one at the far edge of the board that you rarely press.

Are all hot-swappable keyboards compatible with all switches?

No, and this is where the label oversells. The socket decides what fits. A board with 3-pin sockets takes 3-pin switches, and a 5-pin switch fits only after you clip off its two plastic legs. A 5-pin board has extra holes and usually takes both kinds, though a 3-pin switch can wobble a little more. Epomaker’s page for the TH65 describes a 5-pin hot-swappable PCB that makes it easy to replace compatible switches without soldering, and its TH80 V2 Pro page says it takes 3 or 5-pin switches. YUNZII says its B75 PRO sockets are compatible with 3-pin or 5-pin switches. Read the wording each time.

There is a second catch with Hall-effect boards. Attack Shark lists its X68 HE as hot-swappable, but it uses magnetic switches, so an ordinary mechanical switch is not necessarily a drop-in replacement. If the keyboard is magnetic, check which switches the maker sells for it before you buy any.

How to check that a keyboard is really hot-swappable before you buy it

• Look for the words hot-swappable PCB or hot-swap sockets in the spec table, not just in the product title.
• Find the pin format. A board that lists both 3-pin and 5-pin support is the most flexible; a 3-pin-only board needs 5-pin switches clipped first.
• Check the box contents for a switch puller and keycap puller. If they are not included, add them to the cart.
• Ask which switches the maker sells for it. A magnetic or Hall-effect board needs its own switch type.
• Find out how the maker treats the warranty if you open the board.

Which switches are worth trying first?

Switches fall into three feels. Linear switches go straight down with no bump, tactile switches have a small bump partway through the press, and clicky switches add an audible click on top of the bump. Quiet versions of linear and tactile switches exist too, which is where Epomaker’s silent options come in. A first swap that makes sense is the opposite of what the board shipped with. If it came with a linear switch, try a tactile one. If it came with a tactile one, try a silent linear one. You learn more from one change than from three.

Do you need a hot-swappable keyboard?

There are three reasons to buy one.

• You want to try other switch types. Linear, tactile and quiet versions feel and sound different. A hot-swap board lets you test them. Epomaker sells silent options such as the Sea Salt Silent V2 for the TH80 V2 Pro.
• A switch dies. One failed key becomes a quick swap instead of a repair job.
• You plan to resell or pass the board on. A board with swappable switches is easier to refresh.

Reasons to skip it: you like the switches the board came with, you are buying a cheap membrane keyboard, or you simply do not want a hobby. The YUNZII ACTTO B305 is a good example of a board where it is not on offer at all, since YUNZII lists it as a membrane keyboard that is not hot-swappable.

If you are shopping for typing comfort rather than looks, Creativindie’s list of Bluetooth keyboards for writers is built around long sessions rather than switch swapping.

Hot-swappable keyboards on this site

Several of the boards covered here list hot-swap sockets: the Attack Shark X68 HE, the pink Epomaker TH65, the Epomaker x AULA F75 and the RK S98 Pink Edition in the pink gaming keyboards guide, the Epomaker TH80 V2 Pro in the pink wireless keyboards guide, and the YUNZII B98 PRO and B75 PRO in pastel keyboards beyond pink. The pink and pastel keyboards roundup and the dark aesthetic keyboards guide both mention hot-swap options too, and the gaming keyboards roundup covers mainstream picks.

Hot-swappable keyboard questions

Is hot-swappable the same as customizable? No. Hot-swap means the switches come out. Remapping keys and lighting is software. Some boards do both, some only one.

Can I swap the switches on any keyboard? Not on a membrane keyboard such as the YUNZII ACTTO B305, which has no switches to pull. Hot-swap is a feature of mechanical keyboard circuit boards with sockets, and low-profile boards vary, so check the spec for each one.

Does swapping switches void the warranty? It depends on the maker. Look at the warranty page for the specific board before pulling anything out.
