Mechanical vs. Membrane Keyboards: What’s the Difference?

If you're shopping for a new keyboard, you've likely encountered the terms "mechanical" and "membrane" being thrown around. But what exactly makes these keyboard types different, and which is better suited to your needs? This guide breaks down the key distinctions between mechanical and membrane keyboards.

What is a Mechanical Keyboard?

Mechanical keyboards use individual mechanical switches under each keycap that actuate (register a key press) when the key is pressed down fully. These switches come in different varieties with unique feels and sounds, such as:

Cherry MX switches: Very popular. Reds are linear/smooth, blues are clicky, browns are tactile non-clicky.

Gateron switches: Comparable quality to Cherry MX but often smoother at a lower cost.

Kailh switches: Also high quality but slightly scratchier than Cherry or Gateron.

Each switch has a metal spring that propels the keycap back up when released. Mechanical switches are more durable than membranes with lifespan rated 50-100 million key presses. They offer higher tactile feedback and travel distance (typically 4mm). Switch styles cater to preference from gaming to typing.

What is a Membrane Keyboard?

Membrane keyboards contain a thin plastic membrane beneath each key coupled to a rubber dome. Pressing a key compresses the dome and triggers the keystroke sensor contact points etched into the plastic membrane.

Rubber dome switches feel spongy and click at the actuation point, then bottom out without a strong tactical bump.

Scissor switch keyboards feature modified rubber domes cradled by plastic assemblies for a semi-mechanical feel.

Other hybrid designs integrate rubber and metal components for better feedback.

Membranes actuate at higher points in their travel stroke versus mechanical switches, resulting in less responsive input and fatigue over long sessions. Durability ratings reach 10-30 million keystrokes typically.

Other Considerations

Quality membrane keyboards deliver noiseless, lightweight operation affordable for general use. But mechanical models deliver premium build quality, customization, longevity exceeding 100 million clicks, and satisfying tactile experiences for dedicated users.

Membranes suffice for basic tasks, while mechanical brings immersive gaming with programmable macros and typing comfort through adjustable actuation points and diverse switch profiles for any preference.

While membranes impress on budget, mechanical keyboards deliver an investment into high-quality input catered to your specific needs through modularity, tune-ability and lasting performance over years of use.
