Sparkfun Cherry MX2A Keyswitch - Blue

The Cherry MX2A Blue is a clicky mechanical keyswitch engineered for custom keyboards, replacements, and embedded human-machine interfaces. Known for precision, consistency, and durability, Cherry MX switches are a staple for keyboard manufacturers, makers, and enthusiasts. The MX2A generation enhances the original design with premium lubrication, optimized springs, and refined housing geometry, offering smoother key travel, reduced noise, and improved typing feel, while remaining compatible with standard MX keycaps and PCBs.

The MX2A Blue switch provides both tactile and audible feedback with its distinct click at the actuation point, making it ideal for users who prefer a traditional mechanical keyboard experience. This feedback ensures clear confirmation of key presses, enhancing the typing experience for those who appreciate a noticeable response.

With a lifespan of 50 million actuations, the MX2A architecture includes several enhancements: a precisely engineered upper housing, a specialized two-part switching slide/stem for a distinct click sound, self-cleaning gold-plated contacts for corrosion protection, and a high-density precision coil spring for consistent pressure resistance. The dual-functional housing base, made from a plastic polymer/glass-fiber blend, serves as both the internal mount and external mounting surface.

A unique feature of the Cherry MX2A housing is its built-in recess for a standard 3mm LED, allowing for easy integration of illumination under keycaps. This makes it simple to add a personal touch to your keyboard with customizable lighting options.
