Which keyboards can use it?
The Gateron Low Profile Red needs a Gateron low-profile board; low-profile footprints differ between makers, and Kailh Choc and Gateron low-profile switches cannot share a PCB, such as the Keychron K3 (V2). It is not compatible with standard MX mechanical hot-swap sockets. Check the keyboard manufacturer's supported-switch list before buying.
