Actuation Force

Switches

The force required to actuate the switch and close the circuit, measured in grams, which affects typing speed and comfort.

Related Key Terms

LubeSwitches

The application of specialized lubricant to switch or stabilizer components to reduce friction and noise, resulting in smoother movement and improved sound.

Switches

The addition of a thin film between the top and bottom housing of the switch to improve stem stability, prevent wobbling, and enhance the sound.

Switches

An advanced mod where parts from different switches are combined to create a new switch with a customized blend of desired features.

Switches

Switches that provide tactile feedback with a small bump during the press, offering a satisfying feel for users who prefer physical response.

Switches

Switches that offer a smooth and consistent motion when pressed, without tactile feedback or a click sound.

Sound TestSwitches

The opposite of Thock — a high-pitched, sharp sound profile. A clacky sound is achieved by building a keyboard with a metal case, no foam, and switches that produce higher-frequency sounds.

Switches

The point during a key press where the electrical circuit closes, sending the command to the computer. This determines the typing speed and overall feel of the switch.

Polyoxymethylene
PlatesSwitches

A plastic material used for plates and switch components, known for its flexibility, smoothness, and ability to produce a deep “thock” sound profile.

Switches

A longer-than-usual stem (the central part of the switch) that reduces the travel distance to the bottom of the switch, creating a sharper and “cleaner” typing feel.

LubeSwitches

Switches that come pre-lubed from the factory with specialized lube to ensure smooth operation and minimize unwanted noise.

Switches

Switches that combine tactile feedback with a loud, distinctive click sound when pressed, typically noisier than other types of switches.

LubeSwitches

A specialized lubricant for stabilizers and switches, designed to improve smoothness and eliminate noise or a “scratchy” feel while typing. Popular lubes include Krytox 250G0, Krytox 105, and Krytox XHT-BDZ.

Switches

The small units located beneath each key on a mechanical keyboard, responsible for closing the electrical circuit when pressed. They feature a spring mechanism that provides tactile feedback and a unique sound.

HE
Switches

A technology where the circuit is closed by the proximity of a magnet within the switches to the PCB, rather than physical contact. This allows for maximum precision in setting the actuation point, making it ideal for gamers who require rapid response times.

Switches

A version of the stem with a square frame around it, providing protection against water and dust intrusion. Common in some advanced switches.

Switches

Switches where the circuit is closed by blocking light instead of physical metal contact, enabling extremely fast response times, making them ideal for gaming.

Switches

The central part of the switch that connects to the keycap and moves downward when pressed. It affects the key’s stability and the overall typing feel.
