What Is a Mechanical Keyboard Switch?
A mechanical switch is an individual mechanism placed under each key of a keyboard. Unlike membrane keyboards, where keys rely on a rubber dome sheet, mechanical switches use physical components such as springs, stems, and metal contacts to register keystrokes.
Most switches share a common structure:
- Stem – the moving part that determines switch feel
- Spring – provides resistance and returns the key upward
- Housing – encases the switch components
- Metal contacts – register the keypress electronically
The combination of these parts creates different tactile sensations and sound profiles.
The Three Main Types of Mechanical Switches
Mechanical keyboard switches are generally divided into three categories:
Each offers a distinct typing experience.
Linear switches provide a smooth, uninterrupted keystroke from top to bottom. There is no tactile bump or audible click during actuation.
Tactile switches include a noticeable bump during the keypress that signals when the key has actuated. They do not usually produce a loud click sound.
Clicky switches combine tactile feedback with an audible click sound during actuation. They are famous for the classic “typewriter” feel.
Silent Switches
Silent switches are specially designed mechanical switches that reduce typing noise while preserving the feel of traditional mechanical keyboards. They are popular among office workers, streamers, students, and anyone who shares a workspace or prefers a quieter environment. Silent switches are available in both linear and tactile types.
Unlike standard switches, silent variants include small rubber dampeners or internal cushioning components that soften the impact when a key bottoms out and returns upward.
