What You Need Before You Start
Here's a list of all the items you'll need before hot-swapping:
- Hot-swappable keyboard: This guide only applies to hot-swap keyboards
- Replacement switches: Before hot-swapping, you should already know which switches you want
- Switch puller: An essential tool for replacing switches
- Keycap puller: Essential for removing keycaps safely without scratching the plastic
Note: Most hot-swappable keyboards come with a switch puller and keycap puller right out of the box.
Checking Your Switch Compatibility
There are two types of switches: 3-pin and 5-pin. 3-pin switches have two metal prongs and one central plastic peg, while 5-pin add two extra plastic legs on the sides for more stability.
Some keyboards only support 3-pin switches, but most support both. If you try to force a 5-pin switch into a 3-pin keyboard, the switch will not fit down into the socket. Though, 3-pin switches can fit into 5-pin keyboards.
To check what switches a keyboard is compatible with, look at the switch socket on your keyboard. 3 holes means it only supports 3-pin switches, and if it has 5 holes, it supports both.
5-pin switches can be used in 3-pin keyboards by clipping the two extra plastic legs flush with flush cutters. It's a solid backup option, but remember that it's irreversible.
Step-by-Step: How to Remove Your Old Switches
- Unplug the keyboard: Always do this first. If it's wireless, turn it off.
- Remove the keycaps: Use a keycap puller to remove keycaps by hooking under two opposite corners and pulling straight up. Avoid wiggling side to side as it can damage the stem.
- Position the switch puller: Place the two prongs on the top and bottom edges of the switch, where the plastic clips are, then squeeze gently until they grip.
- Pull straight up: Remember to pull straight up, and not at an angle. Angled pulls are the most common cause of damaged sockets.
- Inspect the socket: Check for any debris or damage before installing new switches.
To keep things organized, do this process on every switch row by row rather than randomly. This makes it easier to track progress, especially on larger keyboards.
Step-by-Step: How to Install New Switches
- Check for bent pins before inserting: Visually inspect the pins on each switch before installing. A slightly bent pin is easy to straighten with a fingernail or tweezers, but impossible to fix once it's been forced into the socket.
- Align the pins: Align the switch pins with the corresponding holes in the socket, making sure the switch is oriented correctly before pressing down.
- Press straight down firmly: Push the switch directly down into the socket until you hear or feel a snap or click.
- Test before replacing keycaps: Plug in the keyboard and press each newly installed switch to confirm it registers.
- Replace the keycaps: Press each keycap straight down onto the switch stem until it clicks into place.
If a switch feels wobbly, doesn't click into place, or doesn't register, don't force it. Pull it out, check the pins, and re-insert it.
Common Mistakes to Avoid
- Forcing a 5-pin switch into a 3-pin socket without clipping: The extra legs will prevent the switch from inserting properly and can damage the socket.
- Pulling switches at an angle: The most common cause of damaged sockets. Always pull straight up.
- Not checking for bent pins before inserting: Inserting bent pins makes them even more bent than they already were. Slightly bent pins can be straightened.
- Not testing your switches before reinstalling keycaps: If you reinstall a keycap and then the switch doesn't register, you'll have to uninstall the keycap again. A time-costly mistake.
- Using too much force: Hot-swap sockets are designed to accept switches with moderate pressure. If it's not going in smoothly, it usually means a bent pin or incorrect orientation. Forcing the switch damages the socket permanently.
Conclusion
Hot-swapping is one of the easiest ways to personalize your keyboard.
The whole process takes under 10 minutes once you know what you're doing; and there's almost no risk if you follow the steps.

FAQ
Do I need any special tools to hot-swap keyboard switches?
A switch puller and keycap puller are the only essential tools. Most hot-swap keyboards include those in the box.
Can I hot-swap switches without removing the keycaps?
No. You need to remove the keycaps first to access the switches underneath.
Will hot-swapping void my keyboard warranty?
It depends on the manufacturer. Hot-swap keyboards are designed for switch swapping, so most brands allow it, but check your warranty terms to be sure.
What's the difference between 3-pin and 5-pin switches?
3-pin switches have two metal prongs and one central plastic leg; 5-pin switches add two extra plastic legs for more stability. Most hot-swap keyboards support both, but always check your socket before buying.
How many times can I hot-swap switches before the socket wears out?
Most hot-swap sockets are rated for 100+ insertions. With normal use, they'll outlast the keyboard itself.
Can I mix different switch types on the same keyboard?
Yes. That's one of the biggest advantages of hot-swap. You can use different switches per key, such as linear switches on WASD and tactile switches on the rest.
