Cherry MX2A Keyswitch - Brown

Product Overview

The Cherry MX2A Brown is a tactile mechanical keyswitch designed for custom and replacement keyboards, as well as embedded human-machine interfaces. Cherry MX switches are known for their precision, consistency, and long operating life, making them a standard choice for keyboard manufacturers, makers, and enthusiasts alike. The MX2A generation builds on the original MX design with factory-applied premium lubrication, an optimized spring, and refined housing geometry to provide smoother key travel, reduced spring noise, and improved typing feel while maintaining compatibility with standard MX keycaps and PCBs.

Focused and Noticeable

The MX2A Brown provides a tactile bump without an audible click, giving users physical feedback as the key actuates while remaining relatively quiet. This makes it well-suited for general typing, programming, and mixed gaming applications where tactile confirmation is preferred without the additional noise of clicky switches. To achieve its 100-million actuation lifespan, the MX2A architecture introduces several upgrades:

• Upper Housing: CAD-engineered with sub-0.01mm tolerances to ensure precise switching-slide guidance.
• Tactile Switching Slide/Stem: Engineered to control pre-travel and keystroke feel, featuring a bulged TLS surface that delivers noticeable tactile feedback to communicate the exact point of actuation.
• Gold Crosspoint Contact: Self-cleaning, gold-plated triangular cross-contacts meet at precise right angles to provide permanent corrosion protection.
• Precision Coil Spring: The high-density molecular structure of the spring’s metal alloy is individually calculated and optimized to provide consistent pressure resistance for the switch's specific actuation force.
• Dual-Functional Housing Base: Engineered from a plastic polymer/glass-fiber blend to serve as both the internal mount for the switching mechanism and the external mounting surface for the keyboard.

The Cherry MX2A housing also includes a built-in recess that accommodates a standard 3mm LED. This allows you to easily add your choice of illumination under a key cap. If you need an easy way to incorporate this switch into a prototype, be sure to grab our matching breakout board for simple wiring!
