Do Mechanical Keyboard Switches Need to Be Broken In?

No—new mechanical keyboard switches do not need to be broken in before you use them. Repeated presses may change a switch’s feel or sound, but whether that change is noticeable or welcome depends on the switch. Treat break-in as an optional experiment, not a required step in a build.

What does breaking in a switch mean?

In keyboard discussions, “break-in” usually means cycling a switch—pressing and releasing it repeatedly—in the hope that contact between its moving parts changes slightly. People often discuss it as a way to make a switch feel smoother by reducing friction. But that is not a guaranteed result, and there is no single number of presses that applies to every model.

There is some documented, switch-specific evidence that repeated cycling can change a switch. An enthusiast review tracked Diamond Avalon switches at 17,000, 34,000 and 51,000 actuations. The reviewer described some early changes as minor; later observations included changes in texture, sound and stem wobble. At one point, the reviewer also questioned whether a sound change might reflect variation between switches. This is a useful example of why break-in should not be treated as a predictable upgrade: one model’s observations do not establish what will happen with another.

A separate, preliminary instrumented investigation shared by an RTINGS staff member reported changes in measured switch characteristics after repeated actuations, with differences between models. It was presented as early work, not as a settled rule for how every switch will change. Together, these examples support a cautious conclusion: cycling can affect switches, but the direction and practical significance of the change are not universal.

Break-in, lubrication and ordinary wear are different

Lubrication means applying lubricant to parts of a switch to reduce friction. Break-in involves repeatedly operating the switch; it does not add lubricant. A switch may be factory-lubed, hand-lubed or unlubed, and cycling it does not make those descriptions interchangeable. Repeated use is also part of a switch’s ordinary life, so “break-in” is not a separate process that guarantees a lasting improvement.

How to compare a switch before and after use

If you are curious whether break-in changes your own switches, make a simple comparison rather than relying on memory. Use one switch, or a few switches of the same model, and keep the rest of the build and your listening conditions as consistent as you can.

1. Record how the switch feels and sounds when new. If it is installed, keep the same keyboard, keycap and typing position for later comparisons.

2. Use it normally for a while. There is no universal break-in duration or target press count to aim for.

3. Listen and type again under similar conditions. Notice any change in scratchiness, smoothness, spring noise or sound at the top and bottom of travel.

4. Decide whether you prefer the result. A perceived difference is useful for your own choice, but it does not prove that every switch of that model—or every typist—will respond the same way.

Sound is especially easy to misread: it depends on the whole keyboard build, including the case, plate, mounting, keycaps, stabilisers and how you type. If you hear a difference, it may be hard to attribute it to the switch alone. A careful comparison can help you judge your preference, but it is not a controlled laboratory test.

Should you break in your new switches?

For most beginners, the practical answer is to install the switches and enjoy them. If you already like their feel, there is no need to add a break-in step. If you are curious, compare them after normal use and decide for yourself; avoid assuming that a switch will become smoother, quieter or better suited to you.

When choosing a switch, break-in reports are only one possible consideration. Explore our mechanical keyboard switch database to search switches and narrow your options using available specifications and filters. Specs can help you compare things such as switch type, force and travel, but they do not show whether a particular switch will benefit from break-in.
