Editing Clicky (section)

==Mechanisms==
===Buckling spring===
[[Buckling spring]]s emit a click when the switch buckles and strikes the inside of the switch barrel. This is the only mechanical design where the actuation and click sound directly correlate.

===Click leaf===
{{Main|Click leaf}}
[[Click leaf|Click leaves]] are the most widely-used design. A folded leaf spring is pulled forward and released by the slider, and the click is emitted when the leaf spring snaps back and collides with the inside of the shell. Possibly introduced by Alps with the [[Alps SKCL/SKCM series]], it has been widely copied.

===Click arm===
In what may be a unique design, [[Hi-Tek Series 725]] switches use an arm similar to that in a [[latching action]] switch, which provides the click and tactility.

===Sliding collar===
Clicky [[Cherry MX]] switches use a sliding collar around the slider that is fired downwards to emit a click, and pulled back up when the key is released. This design has been copied by [[Cherry MX clone]]s.

===Click bar===
This is a straight piece of spring metal placed across the switch, formed from one end of a short helical spring. The slider pushes the bar aside, and after it clears the bar, the bar springs back and strikes the inside of the case. Because the slider has to push the bar aside on the upstroke also, this method provides identical press and release clicks.

Currently this is known from [[Kailh PG1350 series|Kailh PG1350]] and [[Kailh PG1511 series|PG1511 series]].

===Simulated click===
Some keyboards that do not have clicky key switches can emit a "click" sound on key actuation either using a built-in speaker, a dedicated clicker or through the operating system.

* The [[Kinesis Advantage]] has a speaker and the click sound is optional.
* [[IBM Beam Spring Keyboards|IBM Beam Spring keyboards]] have both clicky switches ''and'' typically also a dedicated solenoid to provide click. Some models had speakers.
* Many [[Touch screen#Touch screen keyboards|touch-screen keyboards]] provide click sound on key actuation, often as the only feedback.
* [https://www.grc.com/freeware/clickey.htm ClicKey] is a freeware program for MS Windows that plays a sound on each key press.
