Description: Cherry MX Keyswitches are top-of-the-line mechanical keyboard switches. They’re satisfyingly “clicky”, reliable up to tens-of-millions of key presses, and a standard in gaming and programming keyboards across the globe. This ‘blue’ version Cherry MX Switch is favored by most due to its secondary internal actuator making it less likely to “double-tap.” If you are looking for a noticeably audible and high-quality key switch, this is the perfect option for you!

Most Cherry MX Switches – including this blue, MX1A-E1NW switch we carry – have a recess in their body designed to fit a small 3mm LED. Additionally, the weighting for this switch is just around 50cN (centi-Newtons).

Note: If you are looking for an easy way to incorporate this switch to your project, be sure to check out or breakout board! CLICK HERE!

Customer Comments

  • Would SparkFun carry other models of Cherry MX and ML switches? I mean, not everybody love the Blue ones. And other models like the ML are useful for non-keyboard uses.

  • Where are the keycaps for this switch? Can you please post a link.
