Mechanical vs Membrane Keyboards: What's the Difference?

The keyboard that came with your PC is almost certainly membrane, and most people have never typed on anything else. The difference between membrane and mechanical comes down to feel, lifespan, and price.

How they work

A membrane keyboard uses a rubber dome under each key that collapses when pressed. A mechanical keyboard uses a physical switch under every key. That single difference changes everything about the typing experience.

The trade-offs

• Mechanical: better feel, lasts decades, but louder and pricier
• Membrane: cheaper and quieter, but mushier and shorter-lived

Why mechanical wins for heavy typists

Mechanical switches give tactile feedback that lets you type faster with less effort, and individual switches can be replaced if one fails. Membrane keyboards are a single sheet, so one dead key often means a whole new keyboard.

For occasional use, membrane is fine and cheap. For anyone who types for hours a day, a mechanical keyboard is the upgrade that pays off in comfort and longevity.
