- Linear: smooth, quiet; tactile: a bump; clicky: a bump plus a click.
- Optical and hall-effect switches actuate without metal contacts.
- Hot-swap boards let users change switches without soldering.
The switch under each key decides how a keyboard feels and sounds. Mechanical switches dominate enthusiast and gaming keyboards; contactless optical and magnetic designs are growing fast.
The main families
| Type | Feel | Sound | Good for |
|---|---|---|---|
| Linear | Smooth, no bump | Quiet–medium | Gaming, fast typing |
| Tactile | Bump at actuation | Medium | Typing, office |
| Clicky | Bump + click | Loud | Home typing (not shared offices) |
| Optical | Like mechanical | Varies | Gaming, durability |
| Hall-effect (magnetic) | Usually linear | Quiet–medium | Competitive gaming, adjustable actuation |
Numbers that matter
- Actuation force — commonly 35–65 gf; lighter is faster, heavier reduces typos.
- Pre-travel / total travel — around 2 mm / 4 mm on standard switches, shorter on low-profile.
- Pins — 3-pin fits most plates; 5-pin adds stability on PCB-mount boards.
Hall-effect and optical
Magnetic switches use a Hall-effect sensor to measure key position, so actuation depth can be set in software. Optical switches interrupt a light beam. Neither wears metal contacts.
Where to buy
Complete keyboards: mechanical, hall-effect, optical. Loose switches: mechanical switches, plus switch testers to compare them.
Frequently asked questions
Which switch is quietest?
Silent linear switches with dampened stems, followed by membrane and scissor keyboards.
What is rapid trigger?
A hall-effect feature that resets a key as soon as it starts moving up, so it can be pressed again faster.
