罕见Cherry MX机械轴曝光
Rare Cherry MX mechanical switch exposed
在本次横评中，除了以上大家看到的十几颗Cherry MX机械轴之外，笔者还拿到一颗非常特殊的轴，从外观上看，底座为黑色、轴帽固定卡是灰色、轴帽是黑色，在轴帽固定卡上有一个长方形小孔。
In this review, besides the more than 10 Cherry MX mechanical switches you have seen, I have also received a very special switch. On the outside, it has a black bottom, gray upper, black stem, and a rectangular orifice on the upper cover.
当第一次按下轴帽时，轴帽会下陷不再弹起，当再次按下轴帽时，轴帽完全弹起，如此反复循环，与某类可弹起式开关非常类似，由于我们不知道它的来历，这里暂且称之为开关式机械轴。
The first time the stem gets pressed, it stays down and doesn't bounce back up. The next time it's pressed, it bounces up completely. The switch cycles between these two states, similar to certain retracting/latching switches. Since we don't know where it came from, we'll just call it a latching mechanical switch.
将这颗特殊的机械轴拆解之后，笔者在轴帽上发现一个从来没有见过的特殊部件，一个小型的三叶齿轮，可以活动，这也就不难理解为什么会出现当按下轴帽时出现的开关式起伏。
After disassembling the special mechanical switch, I found a part on the stem that I've never seen before. A small 3-tooth gear. No wonder the switch can be lock and unlocked when pressed.
对于这款特殊的Cherry MX机械轴，我们暂且还不了解其特殊用途，但是独特的设计让大家看到了希望，除了青、茶、黑、白四大经典机械轴，Cherry仍在继续开发新轴来满足不同的需求。在网络上曾经出现过黄色机械轴（据说是来自台湾的伪轴）和红色机械轴（没有见到实物）的消息，同样非常罕见。
We don't yet know where this special switch is used, but the unique design gives us hope that Cherry is still developing new switches for different needs. We've seen yellow stems (allegedly fake from Taiwan) and heard about red stems* online, which are also very rare.
- This article was written in 2008 when the red stem switches were not yet available.
