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. With the SparkFun Cherry MX Switch Breakout we have made the switches more easily adaptable to breadboard or perfboard-based projects. The Cherry MX Switch Breakout is a perfect prototyping tool for projects ranging from a single-key user-input to fully-custom 101-key keyboards.

In addition to breaking out the switch contacts to breadboard-compatible headers, the Cherry MX Switch Breakout also provides access to an optional switch-mounted LED. Plus, the pin break-outs are designed with keyboard matrix-ing in mind, so you can interconnect as many boards as you’d like into a row-column configuration, keeping the I/O-pin requirements as low as possible.

Note: If you are looking for a Cherry MX Switch to use with this breakout, we’ve got you covered! CLICK HERE!

Customer Comments

  • wont one need transistors to drive LEDs in case you are connecting several of them to the microcontroller?

  • Any 3D CAD or mechanical drawings for this PCB?

  • is this just one breakout board for 2 dollars? Sounds very pricey to me when Techkeys sells something similar for 40cents each. Any way to get a price reduction, because if I need 80 boards i rather save the money and get it from techkeys.

  • You guys screwed up the jumper land pattern. The jumpers are all shorted with a trace. Please fix for next revision.

    I was able to cut the trace with an xacto knife.

      Nope, that’s intentional. Check the Assembly Tips section of the hookup guide for more information on why we designed the board this way.

Works Great!

These breakout boards were a great help in making my custom keyboard. I didn’t end up using the leds, but I popped a diode on, soldered them together and it’s working great so far. They are handy little boards.

Works perfectly

Using them for a project emulating old console buttons on military-style machines. Work beautifully!
