Sparkfun Cherry MX2A Keyswitch - Brown

The Cherry MX2A Brown is a tactile mechanical keyswitch perfect for custom and replacement keyboards, as well as embedded human-machine interfaces. Known for precision, consistency, and durability, these switches are a top choice for keyboard enthusiasts and manufacturers. The MX2A series enhances the original MX design with premium lubrication, an optimized spring, and refined housing geometry, ensuring smoother key travel, reduced noise, and an improved typing experience, all while maintaining compatibility with standard MX keycaps and PCBs.The tactile bump of the MX2A Brown offers physical feedback without an audible click, making it ideal for typing, programming, and mixed gaming. Users benefit from the tactile confirmation of key actuation without the additional noise typical of clicky switches, providing a quieter yet responsive typing experience.This keyswitch boasts a 100-million actuation lifespan, thanks to several innovations. The upper housing is CAD-engineered with sub-0.01 mm tolerances for precise guidance. The tactile switching slide is designed for controlled pre-travel and keystroke feel, featuring a bulged surface for noticeable tactile feedback. Gold-plated crosspoint contacts ensure permanent corrosion protection, while the precision coil spring offers consistent pressure resistance tailored to the switch's actuation force.The dual-functional housing base, made from a plastic polymer and glass-fiber blend, serves as both the internal mount for the switching mechanism and the external mounting surface for the keyboard. Additionally, the housing includes a built-in recess for a standard 3 mm LED, allowing easy customization with illumination under the keycap. For prototyping, a matching breakout board is available for straightforward wiring.
