03 / WHY BLUE
Three reasons to choose Blue.
Users Who Prefer Clicky Switches
MX2A Blue is designed to produce an audible click. The sound is part of the switch experience rather than something the design tries to hide.
Deliberate, Feedback-Focused Typing
The pressure point gives each keystroke a clearly defined event compared with a smooth linear switch.
04 / THE KEYSTROKE
Clear Tactile Click Feedback
MX2A Blue combines a defined tactile pressure point with an intentional audible click. The switching event is designed to be noticeable both by touch and by sound.
Choose MX2A Blue when the click itself is part of the typing experience you want.

11 / IN DETAIL
About CHERRY MX2A Blue Switches
50 cN Actuation
The switch electrically actuates at 50 cN, while the tactile pressure point reaches 60 cN. These are two different measurements and should not be treated as the same specification.
Full-Travel MX Feel
MX2A Blue uses 2.2 mm pre-travel and 4.0 mm total travel, keeping the full-travel format associated with traditional CHERRY MX switches.
Sound & Feel
MX2A Blue is intentionally audible. Its click mechanism creates acoustic feedback during the switching event rather than relying only on bottom-out or keycap noise.
Before You Choose
Clearly Audible. The click is intentional, so MX2A Blue may not suit shared offices, libraries or other noise-sensitive environments.
More Pronounced Than Linear Switches. The tactile pressure point and click mechanism create a more noticeable key event than a smooth linear switch.
Check Compatibility Before Ordering. The PCB and hot-swap socket must support the actual mounting configuration of the version sold on this page.
Explore CHERRY switches or use the MX2A Family Comparison to choose your preferred feel.
