Now that we have some context, let's go layer by layer through the key components of 2019's butterfly switch: Topping it all off is the key cap. This has a handy label to tell users which key is broken. The hinged white bracket is the "butterfly" mechanism controlling the key's motion—stabilizing it so as to travel up and down without tilting or wobbling.
  • Now that we have some context, let's go layer by layer through the key components of 2019's butterfly switch:

  • Topping it all off is the key cap. This has a handy label to tell users which key is broken.

  • The hinged white bracket is the "butterfly" mechanism controlling the key's motion—stabilizing it so as to travel up and down without tilting or wobbling.

  • Nesting within that bracket is a transparent cover that flexes with each key press, while keeping contaminants away from the dome switch underneath. The black dot at its center concentrates the force of your key press onto the switch.

  • The main character of this assembly is the springy metal dome switch. It deforms when the key is pressed, bridging the board's six contacts—and then bounces back when you release the key.

  • Underneath the dome switch are six metal pads. A keystroke registers whenever the top center pad is shorted to any of the other five pads.

  • To wrap it up, the silicone membrane covers the butterfly mechanism to keep debris from getting in and jamming it.

现在我们梳理了来龙去脉,要开始一层一层的拆开2019款蝶式键盘按键的零件了。

在最上层拆下来的是键帽。这种键帽设计巧妙,以至于让人一眼就能看出来哪个按键损坏了。

这个白色的铰链式托架蝶式结构中用来控制按键运动的部分——保持稳定的上下移动它,千万不要四下晃动它,这样才能把它完美的拆下来。

垫在托架里面的是一个透明的盖子,用来阻止污垢进入穹顶式托架,并且在每次按下按键的时候收缩。它中间的黑色圆点用来集中你敲击按键的力量。

这个组合的主角是有弹性的锅仔片。它在按键按下的时候变形,将压力传递给六个底板上的触点,然后在你不按按键的时候将按键弹回原位。

在锅仔片下面是六个金属垫片,其中任何一个垫片短路时都会触发按键记录器,以输入字符。

总结一下,硅胶薄膜盖住蝶式键盘的机械结构以阻止污垢进入按键,把按键塞住。
