Part 5: Hot-Swap Guide (Changing Switches)

One of the Z-88’s best features is hot-swappable sockets (Outemu standard). If your model says "Hot-Swappable" on the box, you can change switches without soldering.

What you need:

Switch puller (included with many Z-88 units).
Keycap puller.
Compatible switches: Outemu, Akko, or any 3-pin mechanical switch (Cherry MX will work but may feel tight).

Step-by-step:

Use the keycap puller to remove the keycap.
Use the switch puller to grip the top and bottom of the switch.
Gently wiggle and pull straight up.
Insert the new switch, ensuring the two metal pins align with the sockets.
Press firmly until you hear a click.
Replace the keycap.

Caution: Do not bend the pins. If a key doesn't work after swapping, remove the switch, straighten pins, and reinsert. E-yooso Z-88 Manual
