ERGONOMIC ANGLE DESIGN
Two level adjustable rubber feet makes the new K3 more comfortable to type on.
HOT-SWAPPABLE OPTION
We also provide a hot-swappable version for your choice, which means you can customize your typing experience without soldering, pop them in and it's done.
We all have our unique typing preferences, that’s why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We’ve implemented a MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.
You can easily hot-swap every Optical switch in a few seconds to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.
MECHANICAL OR OPTICAL?
We’ve overcome different technical challenges to redesign both the low profile Gateron Mechanical switch and low profile Keychron Optical switch in order to elevate the typing experience while enhancing its reliability on the ultra-slim keyboard.
Mechanical Switch

Durable low profile Gateron Mechanical switch with a 50 million keystroke lifespan to provide an unrivaled tactile responsiveness
Optical Switch

With the MX-styled stem housing and 0.2ms ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a 70 million lifespan much greater than industry standards.
*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.
ALTERNATIVE KEYCAPS
![Keychron K3 ultra_slim Hot_swappable wireless mechanical keyboard Mac Windows iOS Android Keychron low profile Optical and Gateron low profile mechanical switch desktop setup](https://cdn.shopify.com/s/files/1/0059/0630/1017/t/5/assets/pf-f109ef5d--KeychronK3ultraslimwirelessmechanicalkeyboardmacwindowsiOSandroidKeychronOpticalGateronmechanicalswitchredbluebrownkeycapcompareRoccatVulcan120AimoCherrylowprofilekeycap.jpeg?v=1602593873)
We’ve spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.
It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.
