Why Lubricate Switches?

by

For keyboard enthusiasts, customizing and maintaining 75% keyboards is a rewarding hobby. One essential aspect of this customization is switch lubrication. Proper lubrication can enhance the feel, sound, and overall performance of your keyboard switches.

Why Lubricate Switches?

Lubricating switches reduces friction between moving parts, leading to a smoother keystroke. It also minimizes noise, making your keyboard quieter and more pleasant to use. Additionally, lubrication can extend the lifespan of your switches by decreasing wear and tear.

Types of Lubricants

Choosing the right lubricant is crucial. Common types include:

  • Plastic-compatible lubricants: Designed specifically for keyboard switches, such as Krytox 205g0 or Tribosys 3204.
  • Silicone-based lubricants: Often used for damping, but less common for switches.
  • Oil-based lubricants: Generally not recommended due to potential damage to plastics.

Tools Needed

To lubricate switches effectively, gather the following tools:

  • Switch opener or keycap puller
  • Fine brush or applicator
  • Lubricant of choice
  • Small container for holding switches
  • Optional: Desoldering tools if removing switches from PCB

Step-by-Step Lubrication Process

Follow these steps for optimal results:

1. Remove Keycaps and Switches

Carefully remove keycaps using a keycap puller. If your keyboard has hot-swappable switches, gently pull out each switch. For soldered switches, desolder before proceeding.

2. Open the Switches

Use a switch opener to carefully separate the top housing from the bottom housing. Be gentle to avoid damaging the plastic parts.

3. Apply Lubricant

Using a fine brush or applicator, apply a thin layer of lubricant to the stem, spring, and contact points. Avoid over-lubricating, as excess can cause sluggishness.

4. Reassemble Switches

Carefully reattach the top housing to the bottom housing, ensuring it snaps into place securely.

5. Reinstall Switches

Insert the lubricated switches back into the keyboard PCB. Solder if necessary, then replace keycaps.

Tips for Effective Lubrication

Keep these tips in mind:

  • Use a small amount of lubricant to avoid sluggishness.
  • Work in a well-ventilated area to avoid inhaling fumes.
  • Test a few switches first to determine the optimal amount of lubrication.
  • Be patient; careful application yields the best results.

Common Mistakes to Avoid

New enthusiasts often make mistakes that can impact the performance of their switches:

  • Over-lubricating, leading to sluggish keys.
  • Using incompatible lubricants that damage plastics.
  • Applying lubricant unevenly, causing inconsistent feel.
  • Forgetting to clean switches before lubrication, trapping dirt and debris.

Conclusion

Switch lubrication is a vital step for enthusiasts seeking to customize their 75% keyboards. With the right tools, lubricants, and techniques, you can greatly improve your keyboard’s feel and sound. Patience and practice are key to achieving professional results.
