-[* black] Let's take a closer look at the ''key'' components of a 2019 butterfly switch:
- [* black] Key cap
- [* black] Butterfly mechanism—physically stabilizes the thin key cap, ensuring that it travels up and down without wobbling or tilting
- [* black] Dome cover—frame with a flexible membrane that allows the keypress force through while keeping contaminants out of the contacts
+[* black] Now that we have some context, we can take a closer look at the ''key'' components of 2019's butterfly switch:
+ [* black] Topping it all off is the key cap. This has a handy label to tell users which key is broken.
+ [* black] Attached to the key cap, the butterfly mechanism controls the key's motion, stabilizing it and ensuring that it travels up and down without wobbling or tilting.
+ [* black] The dome switch cover is a frame supporting a flexible membrane that moves with the key, while keeping contaminants away from the dome switch underneath.
[* black] Metal dome—supplies the spring force for the key while also serving as the electrical switch by deforming and bridging the board contacts
[* black] Board contacts—(needs update) connecting the central pads with any of the four outer pads signals a keypress
[* black] Silicone sleeve—provides ingress resistance for the butterfly mechanism to prevent it from being physically jammed
