Hot-Swappable Mechanical Keyboards — 3 Picks Under $100
hot swappable mechanical keyboards are an easy way to get customization and repairability without learning soldering. If you’re shopping on a budget but still want the flexibility to change switches later, these three boards deliver solid performance, hot-swap support, and unique strengths: the Redragon K668 (full-size, budget), Ajazz AK820 (compact 75% with knob), and YUNZII B75 (gasket mount comfort). Below I compare them head-to-head and tell you which to pick depending on your priorities.
If you’re new to hot-swappable keyboards and want to understand whether they’re worth it, check out our beginner guide on what a hot-swappable keyboard is and how it works.
Why hot-swappable keyboards matter
Hot-swappable keyboards let you pull out a mechanical switch and insert a new one in minutes — no soldering iron required. That means easy repairs, quick testing of different switch types (linear, tactile, clicky), and a low barrier to customizing feel and sound. For beginners, hot-swap is a time-saving feature that reduces long-term cost and frustration.
