How to lube keyboard switches

Overview

Mechanical keyboards are prized for their durability, tactile feedback, and customizability. A key aspect of this customization, and a way to significantly enhance the typing experience, is through lubricating the keyboard switches. Lubrication is the process of applying a thin, even layer of a specialized lubricant to the moving parts of a mechanical keyboard switch. This not only makes the keystroke feel smoother and more consistent but can also deepen the sound profile, reducing any scratchiness or pinging that might be present in stock switches.

Why Lubricate Keyboard Switches?

The primary reasons for lubricating mechanical keyboard switches are:

• Improved Smoothness: Stock switches, especially mass-produced ones, can have a slight amount of friction or "scratchiness" as the stem moves within the housing. Lubricant fills microscopic imperfections and reduces this friction, leading to a significantly smoother and more satisfying keystroke.
• Reduced Noise: Lubrication can dampen vibrations and eliminate the "scratchy" sound. It can also reduce "spring ping" – a high-pitched metallic sound that some springs make.
• Enhanced Tactile Feel: For tactile switches, lubrication can sometimes make the bump feel more pronounced or refined, depending on the type of lube and how it's applied. For linear switches, it results in a more consistent and fluid travel.
• Extended Lifespan: By reducing friction and wear between the plastic or metal components, lubricant can potentially extend the lifespan of your switches.
• Customization: It's a core part of the keyboard enthusiast hobby, allowing users to fine-tune their typing experience to their exact preferences.

Types of Lubricants

Choosing the right lubricant is crucial. Different types are suited for different switches and desired outcomes:

• For Linear Switches: Thicker lubricants like Krytox 205g0 are often preferred. They provide a very smooth, buttery feel and can dampen sound effectively.
• For Tactile Switches: Lighter, thinner lubricants like Tribosys 3203 or 3204 are generally recommended. These lubes aim to preserve the tactility of the switch while still reducing scratchiness. Applying too much or too thick a lube can mask or even eliminate the tactile bump.
• For Clicky Switches: Lubricating clicky switches is generally not recommended, as it can interfere with the mechanism that produces the click sound, often muting it entirely.
• Spring Lube: Springs can be lubed separately using a thinner lubricant or by "bag lubing" (shaking springs in a bag with lubricant). This helps reduce spring ping.

The Lubrication Process

Lubricating switches is a time-consuming but rewarding process. It requires patience and attention to detail.

What You'll Need:

• Lubricant: As discussed above (e.g., Krytox 205g0, Tribosys 3204).
• Small Brush: A fine-tipped paintbrush (size 0 or 00) is ideal for applying lube precisely.
• Switch Opener: A tool specifically designed to safely open mechanical keyboard switches without damaging them.
• Tweezers: Useful for handling small parts like springs.
• Container: For holding disassembled switch parts.
• Optional: Switch films (to reduce housing wobble), O-rings (for keycaps), lube station (to hold switch housings).

Step-by-Step Guide:

1. Disassemble the Keyboard: If your keyboard is pre-built, you'll need to remove the keycaps and then unscrew the PCB from the case. If it's a hot-swappable board, you can often remove switches without desoldering.
2. Open the Switches: Using a switch opener, carefully separate the top housing, bottom housing, stem, and spring from each switch. Work on one switch at a time or organize parts meticulously.
3. Lubricate the Stem: Apply a very thin, even coat of lubricant to the sides (sliders) of the stem. Avoid lubing the legs of tactile stems if you want to preserve tactility.
4. Lubricate the Housing: Apply a thin layer of lubricant to the inside walls of the bottom housing where the stem slides.
5. Lubricate the Spring (Optional but Recommended): You can "bag lube" the springs by putting them in a small bag with a few drops of lubricant and shaking them, or apply a thin coat with a brush. This helps prevent spring ping.
6. Reassemble the Switch: Carefully place the stem back into the bottom housing, ensuring it moves freely. Place the spring on top of the stem. Attach the top housing, ensuring all clips align and snap securely.
7. Test the Switch: Before putting it back into the keyboard, test the switch by pressing it down a few times to ensure it feels smooth and sounds right.
8. Reassemble the Keyboard: Place the lubed switches back into the PCB (or hot-swap sockets). Reassemble the keyboard case and reattach the keycaps.

Tips for Success

• Less is More: It's far easier to add more lubricant than to remove excess. Start with a very thin layer.
• Even Application: Aim for a consistent, thin coat. Avoid thick clumps of lube.
• Consistency is Key: Lubricate all switches the same way to maintain a uniform typing feel.
• Patience: Lubricating switches is a marathon, not a sprint. Take breaks if needed.
• Research Your Switches: Understand the type of switch you have (linear, tactile, clicky) and research recommended lubes and techniques for that specific switch type.

By following these steps, you can significantly enhance the typing experience on your mechanical keyboard, making it smoother, quieter, and more enjoyable to use.
