How to Lubricate Mechanical Keyboard Switches

Lubricating mechanical keyboard switches is a popular method in the keyboard community to improve keyboard performance and feel. Lubricated switches provide smoother key actuation, reduce friction, and lessen unwanted noise. This article will walk you through the steps of how to lubricate mechanical switches and what to look out for when doing so.

Why should you lubricate switches?

Lubricating switches offers several key benefits:

• Smoother typing experience : Lubricated switches feel softer and less “scratchy”.
• Less noise : Especially with linear switches, lubrication can reduce the volume of keystrokes.
• Longer life : Reduced friction means your switches will last longer and remain more consistent in their performance.

What you need for lubrication

Before you begin, you will need some important tools and materials:

1. Lubricant : The most common lubricant to use is a thick lubricant such as Krytox 205g0 or Tribosys 3204. Make sure the lubricant is designed for mechanical keyboard switches.
2. Brush : A fine, high-quality brush is necessary to apply the lubricant evenly to the switch components.
3. Switch opener : A special tool to open your switches without damaging them.
4. Tweezers : To handle the small parts of the switches more easily.
5. Switch holder or keyboard soldering iron : If the switches are soldered to the board, you will need a soldering iron to remove them.

Step-by-step instructions: Lubricating mechanical switches

1. Disassemble the keyboard

First, you'll need to disassemble the keyboard to access the switches. If your switches are hot-swappable, you can simply pull them out. Otherwise, you'll need to remove the switches from the board using a soldering iron.

2. Open the switch

Use the switch opener to open the switches. This will give you access to the internal components of the switch, such as the spring, plunger and contact points. Be careful to take the parts apart carefully and not to lose them.

3. Apply lubricant

Take a small amount of lubricant with a fine brush and carefully apply it to the following parts:

• Tappet : Lubricate the area that comes into contact with the housing to ensure smooth movement.
• Spring : Apply a thin layer of lubricant to the spring to reduce noise and improve feel.
• Housing : If you want, you can also lightly lubricate the inside of the housing, but be careful not to allow excess lubrication to affect the contacts.

4. Reassemble the switch

After all parts have been lubricated, reassemble the switch. Make sure all parts are properly seated and the switch functions as intended.

5. Test the switch

Before you put all the switches back into your keyboard, test a few lubricated switches to make sure the feel and volume are what you expect. You can make adjustments if necessary.

Tips and common mistakes to avoid

• Do not use too much lubricant : too thick a layer can make the switch sluggish and affect the spring movement.
• Avoid lubrication on the contacts : Make sure that the lubricant does not get on the electrical contact points as this may affect the operation of the switch.
• Be patient : Lubrication is a time-consuming process that requires care and patience. Allow enough time to work on each switch thoroughly.

Conclusion

Lubricating mechanical switches is a rewarding task that can significantly improve the typing feel and sound of your keyboard. With the right tools and a little patience, you can modify your keyboard to perfectly suit your preferences. Remember, less is often more - a fine layer of lubricant is enough to achieve remarkable results.
