Cherry MX Switch Breakout

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.

Features:

• Support for 3mm LED
• Footprint for LED current-limiting resistor
• Footprint for switch-isolating diode
• Chain-able in row/column matrices
• Designed to match standard key spacing and keyboard row offsets
