To lubricate switches externally, you can use a fine paintbrush to apply light, precise coats of lubricant like Krytox GPL205-G0 on contact points such as stem rails and housing sides. Alternatively, shaking springs in a sealed bag with a small amount of oil guarantees even coverage and reduces noise from spring ping. Using these methods allows you to improve smoothness and sound without full disassembly. Keep going to discover the best techniques and tips for perfect external lubrication.
Why External Switch Lubrication Improves Feel and Sound
External switch lubrication improves feel and sound by directly targeting friction points that cause scratchiness and uneven keystrokes. When you lube the legs of the switch or apply lubricant to the switch housing surfaces, you effectively reduce noise and improve smoothness. This approach dampens high-pitched scratches and rattles, boosting the acoustic quality of your keyboard. Additionally, using the right lubricant with proper viscosity ensures a balanced sound and responsive feel. Lubricating the outside contact areas, such as the stem sides and switch housing, minimizes stickiness and irregular resistance caused by factory imperfections or wear. While it doesn’t offer as precise an effect as internal lubing, external lubrication is accessible and safe, addressing key feel and sound without risking damage. This method makes your switches feel more consistent and sound more refined during every keystroke.
The Best Methods to Lubricate Switches Outside
To lubricate switches externally, you’ll want to focus on precise application methods like brushing or using a small lubricant bag. The brush lubrication technique allows you to target friction points carefully, while the bag method offers a quick way to coat multiple switches evenly. Both methods help you improve switch feel without fully disassembling your keyboard. Additionally, using an organized setup with dedicated compartments can streamline your lubrication process and prevent leaks or messes.
Brush Lubrication Technique
Using a fine, thin paintbrush—typically a size 00—allows you to precisely apply a light layer of lubricant directly onto the switch’s stem rails and contact points without opening the switch. This method, known as brush lubrication, is ideal for quickly smoothing out linear switches by targeting visible friction areas.
It helps reduce scratchiness and maintain a smooth keystroke without over-lubricating. Carefully brushing the lubricant guarantees even coverage while avoiding excess buildup, which can cause sluggishness. Only apply a thin coat of switch-friendly lubricant like Krytox GPL205-GDO to prevent affecting the switch’s feel. Keep the brush steady and focus on internal contact points.
This technique is especially effective for linear switches that rely on smooth, frictionless movement. Proper application can also help prevent excess buildup that might attract dust and debris, ensuring consistent performance over time.
Bag Lubricant Method
The bag lubricant method offers an efficient way to lubricate multiple springs simultaneously, saving you time and effort. With this technique, you place springs into a sealed plastic bag, add a few drops of thin lubricant like Krytox 105 or Tribosys 3204, and shake vigorously to coat the springs evenly. This approach guarantees consistent coverage while minimizing lubricant waste compared to brushing.
Typically, 0.1 to 0.15 mL of lubricant per 100 springs is enough to reduce noise and spring ping without over-lubbing. Keep in mind, the bag lubricant method is ideal only for springs and isn’t recommended for stems or housings, as uneven distribution and excess lubricant may occur. Overall, it’s a quick, clean way to prepare springs for a quieter keyboard. Leveraging factory pre-lubrication can further reduce the need for external lubrication, making switches ready to use right out of the box.
When Should You Use Brush Lube Versus Bag Lube?
Deciding whether to use brush lubing or bag lubing depends on the specific part of the switch you’re working on and the type of lubricant involved.
Choose brush or bag lubing based on switch part and lubricant type for optimal performance.
Use brush lubing when you need precise, targeted application on switch housings, stems, or friction contact points to enhance smoothness. It’s particularly useful for thick greases like Krytox 205, where control and minimal waste matter. Avoid using brush lubing for springs, as it can lead to uneven coverage and lubricant waste.
Bag lubing is best suited for springs, allowing quick, uniform coverage by shaking them in a sealed bag with a small amount of lubricant. It’s ideal when lubricating many springs efficiently. Additionally, assembly compatibility is improved when components are properly lubed, ensuring consistent feel across all switches.
Each method complements specific switch parts, ensuring peak performance and feel.
