A switch assembly creates tactile actuation and reset feedback.
What it is
A mechanical switch is a self-contained assembly, often similar to those in mechanical keyboards, that clicks when pressed and springs back when released. Inside, a spring and contact or click element create a defined actuation point. In EDC, switches are often built into clickers and buttons; the type depends on the brand.
How it feels in your EDC
A switch gives a crisp, repeatable press: a clear point where it actuates, a click or bump, and a quick reset. Different switch types range from quiet and smooth to loud and tactile. Many people enjoy the familiar keyboard-like feel.
What to look for
Check the switch type and loudness, and whether it is described as clicky, tactile or linear. Look at press force and whether switches can be replaced, which can extend the piece’s life or change its feel. Keep dust and liquids away from the switch.

是什么
机械开关（Mechanical Switch）是一个独立的组件，常与机械键盘里的开关类似，按下时咔哒作响、松开后弹回。内部的弹簧和触点或发声元件形成明确的触发点。在 EDC 中，开关常内置在按压器和按键里；具体类型取决于品牌。
上手感受
开关带来清脆、可重复的按压：明确的触发点、一声咔哒或段落感，以及迅速的回弹。不同类型从安静顺滑到响亮有段落感都有。很多人喜欢这种熟悉的键盘般手感。
选购要点
确认开关类型和响度，以及品牌描述是清脆（clicky）、段落（tactile）还是线性（linear）。看按压力度以及开关能否更换，更换可延长使用寿命或改变手感。让开关远离灰尘和液体。
