A Complete Guide to Lubricating Mechanical Keyboard Switches

Mechanical keyboards have earned a devoted following among enthusiasts and professionals alike, lauded for their tactile feedback, durability, and customizable nature. Central to the exceptional performance of these keyboards are the switches that lie beneath each keycap.

However, over time, friction and wear from normal use can cause switches to lose their smoothness and crisp actuation, leading to a less satisfying and efficient typing experience. Fortunately, properly lubricating mechanical keyboard switches not only restores their performance but also enhances their overall longevity.

In this guide, we explore the types of switches that benefit from this process and the various lubricants available for the job. You will learn how to properly lube clicky switches, tactile switches, and linear switches with step-by-step instructions on how to effectively apply lubricant to your switches.

What is Mechanical Keyboard Switch Lubrication?

Switch lubrication refers to the process of applying a suitable lubricant to mechanical, electrical, or electronic switches to reduce friction, wear, and noise while improving their performance and longevity. Switches are devices that enable or disable the flow of current in an electrical circuit or control the operation of a mechanical system. These switches often consist of movable parts that come into contact with each other during actuation, and over time, this friction can lead to wear and decreased functionality.

Why do switches need to be lubricated?

By lubricating switches, a thin layer of lubricant is applied to the moving parts, such as actuator stems, sliders, or contacts to create a smooth interface. This lubrication reduces the amount of friction generated during the switch's operation, allowing for smoother actuation, decreased wear on the components, and quieter operation. Moreover, lubrication can prevent switches from malfunctioning or failing prematurely due to excessive friction and wear.

Switch lubrication is particularly important for mechanical switches where users frequently actuate the switches.

In essence, lubing your switches is like an upgrade, a transformation that takes your keyboard from good to exceptional.

What are the benefits of lubricating keyboard switches?

Lubricating the switches on your mechanical keyboard can offer several significant benefits that enhance the overall typing experience and extend the lifespan of the keyboard.

1. Smoother Typing Experience: Lubrication reduces friction between the moving parts of the switches, resulting in a smoother and more effortless typing experience. The keys feel less scratchy and more satisfying to press, making typing more comfortable and enjoyable.
2. Noise Reduction: Keyboards with unlubricated switches can produce audible "scratchiness" or "pinging" sounds when keys are pressed. Lubrication dampens these unwanted noises, creating a quieter keyboard that's less distracting.
3. Improved Responsiveness: Lubricating the switches helps maintain consistent actuation force and reduces "stickiness" in the switches. This ensures that each key press registers accurately and consistently. It also improves typing speed and accuracy.
4. Reduced Wear and Tear: Friction between switch components can lead to accelerated wear and tear, causing the switches to lose their tactile feel and responsiveness over time. Lubrication helps minimize this wear and extends the lifespan of the switches and the overall keyboard.
5. Prevents Switch Sticking and Binding: Over time, dust and debris can accumulate within the switches, causing keys to stick or bind. Lubrication reduces the likelihood of particles becoming trapped and ensures the smooth movement of switch components.
6. Maintenance of Switch Performance: Regularly lubricating keyboard switches as part of maintenance helps to keep the switches in optimal working condition. It helps preserve the original performance of the keyboard.
7. Customization and Personalization: Some users in the mechanical keyboard hobby experiment with different lubricants to achieve a specific feel or sound from their switches. Lubrication allows for customization, tailoring the keyboard's typing experience to individual preferences.
8. Enhanced Durability: Well-lubricated switches are less prone to developing issues such as key chattering (where a single key press registers as multiple presses) or inconsistent actuation. By maintaining proper lubrication, the switches are less likely to fail prematurely.
9. Cost-Effective Maintenance: Lubricating keyboard switches is a relatively simple and cost-effective way to improve keyboard performance and extend its life. It can be done by users themselves, avoiding the need for expensive repairs or replacements.

While lubricating switches can provide significant benefits, lubing your keyboard switches should be done correctly and with the right type of lubricant. Applying too much lube or using the wrong lubricant can have adverse effects such as attracting dust and interfering with switch functionality. Therefore, you should follow proper guidelines and recommendations when you lube your mechanical switches.

Can lubricating switches improve typing experience?

Sure, it might seem like a small tweak. But lubing the switches of a mechanical keyboard can significantly improve the typing experience on mechanical keyboards:

1. Reduced Friction: Lubricants create a smooth surface between the moving parts of the switches, reducing friction during key presses. This reduction in friction makes typing feel smoother and more effortless, as fingers can glide over the keys with less resistance.
2. Enhanced Tactile Feel: Some mechanical switches have tactile bumps or audible clicks that provide feedback when a key is actuated. Lubricating your switches can accentuate these tactile sensations, making the typing experience more pronounced and satisfying for users who appreciate the feel of the keys.
3. Quieter Typing: Mechanical keyboards without lubrication can produce unwanted sounds when keys are pressed. Lubrication dampens these unwanted noises, resulting in a quieter typing experience.
4. Consistent Actuation: Lubricating switches ensures a more consistent actuation force across all keys. This consistency allows typists to develop muscle memory and a better sense of how much force is required to actuate each key accurately, leading to improved typing speed and accuracy.
5. Reduced Fatigue: The smoother and more responsive typing experience from lubricated switches can reduce typing fatigue. Typists may find that they can type for longer periods without experiencing discomfort or strain on their fingers and hands.
6. Improved Accuracy: With reduced friction and improved tactile feedback, typists can better gauge each key press, resulting in fewer typing errors and improved overall typing accuracy.
7. Preventing Sticking and Bouncing: Over time, dust and debris can accumulate in switches, leading to key sticking or key bouncing issues (where a single key press registers multiple times). Lubrication helps prevent these issues.

How often should you lube your mechanical keyboard switches?

How often do you need to lube your switches?

If you're a heavy user, lubing every 6 to 12 months is a good rule of thumb. However, for the casual typists among us, every 1 to 2 years should suffice.

They offer excellent lubricating properties and are known for their low friction. PTFE lubricants can enhance switch smoothness and reduce noise effectively.
3. Dielectric Grease: Dielectric grease is a silicone-based, non-conductive lubricant commonly used for electrical components, including mechanical switches. It provides a smooth feel and helps prevent oxidation and corrosion in electrical contacts.
4. Nano-Oil: Nano-oil is a synthetic lubricant known for its nano-particles that can fill microscopic imperfections in surfaces, reducing friction effectively. It comes in various viscosities, allowing users to choose the level of smoothness they desire.
5. Super Lube: Super Lube is a brand that offers multi-purpose synthetic lubricants suitable for mechanical switches. They provide good lubrication, are non-toxic, and can withstand a wide range of temperatures.
6. Silicone Oil: Silicone oil is another option for lubricating switches, especially for linear switches. It is generally lighter than grease-based lubes and can provide a smoother keystroke.

When choosing a lube, consider the following factors:

• Switch Type: Some lubricants work better with specific switch types. For example, PTFE-based lubes are popular for linear switches, while tactile switches might benefit from a slightly thicker lubricant to maintain the tactile bump.
• Viscosity: Different lubricants come in various viscosities (thickness). A lower viscosity results in a lighter, smoother feel, while higher viscosity provides a slightly more dampened feel. Experiment with different viscosities to find what suits your preferences.
• Application Method: Some lubes come with applicator brushes or syringes, making them easier to apply, while others may require more precise application using a small brush or toothpick.
• Compatibility: Ensure the lubricant you choose is safe to use on plastic and metal components, as some lubricants can cause damage or degradation to certain materials.

When it comes to brands, Krytox GPL 205 Grade 0 is a popular choice for lubing linear switches. It's thick and smooth, giving your keys that buttery feel.

For lubing clicky switches and tactile switches, you might want to go for something thinner like Tribosys 3203.

Can you lube switches without desoldering them?

It is possible to lubricate mechanical switches without desoldering them. However, the process may be more challenging and less effective compared to lubing switches that have been desoldered. Lubricating switches without desoldering is commonly referred to as "switch modding" or "top housing lubing" as you apply the lubricant to accessible parts of the switch without disassembling the entire switch.

Note that lubing keyboard switches without desoldering method might not be effective. Desoldering provides a more thorough job although this requires a bit of skill and precision. After all, desoldering switches from the PCB is a delicate task.

Can you lube hot-swappable keyboard switches?

You can lubricate hot-swappable keyboard switches. Hot-swappable keyboards are designed to allow users to easily remove and replace switches without soldering. This feature provides a convenient way to customize the keyboard's typing experience by trying different switch types or, as you mentioned, lubricating the switches.

When lubing hot-swappable switches, the process is similar to lubing non-hot-swappable switches, but with some important considerations:

1. Switch Removal: Before lubricating the switches, make sure to remove them from the hot-swappable keyboard. Follow the manufacturer's instructions. If you need a switch puller, do it gently to safely extract the switches.
2. Lubrication: Apply a small amount of lubricant to the moving parts of the switch, such as the stem and sliders. Use a brush, toothpick, or applicator specifically designed for lubing switches.
3. Reinstalling the Switches: After lubing the switches, carefully reinstall them back into the hot-swappable sockets. Make sure each switch is seated properly and securely in its socket.
4. Testing: Once all the switches are lubed and reinstalled, test the keyboard to ensure that all keys are functioning correctly and that you are satisfied with the typing experience.

Note that lubing hot-swappable switches may not be as effective as lubing switches that have been desoldered and disassembled. Hot-swappable keyboards have limitations in terms of access to internal switch components, which may prevent you from lubricating certain areas (such as the springs or bottom housing) that would be accessible in a desoldered switch.

Tips and Tricks for Lubing Your Keyboard Switches

Getting lube in your switch can be a delicate process. Here are some tips and tricks to ensure that you're doing the right way to lube your keyboard switches:
