机械键盘如今已不再总是那么“机械”。过去六年来，采用光学、霍尔效应及其他“非接触式”轴体的键盘越来越常见，价格往往也高于传统机械键盘，而传统机械键盘相较于基础薄膜键盘本就已经存在溢价。作为回报，它们承诺带来一些理论上的优势，尤其是对游戏玩家而言。不过在日常使用中，这些差异可能相当细微。
The mechanical keyboard isn't always so mechanical anymore. Over the past six years, keyboards with optical, Hall-effect, and other "contactless" switches have become increasingly common, often going for higher prices than traditional mechanical keyboards, which already command a premium over basic membrane boards. In return, they promise some theoretical advantages, particularly for gamers. In daily use, though, the differences can be pretty subtle.
那么，你究竟是在为什么买单？本指南将剖析最新轴体的工作原理，解释非接触式设计为何日益流行，并说明它们的优缺点究竟在哪些方面真正产生影响。
So what exactly are you paying for? In this guide, we break down how the newest switches work, why contactless designs are becoming more popular, and where their advantages—and disadvantages—really matter.
