What is it?

The Mech Key is a kind of mechanical switch that makes an audible clicking sound when you press it. The tactile click is so good that you can see it on many popular mechanical keyboards.

The Mech Key can detect events such as single press and long press. There is also a RGB LED under the keycap for you to add some backlighting effects.

How this module works?

The clicking sound is produced based on the mechanical structure of the module. Just like other typical button switches, when you press down the button of the mech key, you are actually closing the circuit and letting electric signals pass through. A single button press is a very short time period to power the circuit on and off; while a long press, is closing the circuit for a lonegr time period.

You can program the Mech Key very easily with Codecraft to achieve more creative and challenging projects.
