How to lubricate mechanical keyboard switches properly?
Answer
Properly lubricating mechanical keyboard switches enhances typing smoothness, reduces noise, and extends switch lifespan by minimizing friction between moving parts. The process involves disassembling switches, applying specialized lubricants to critical contact points, and reassembling them with precision. While the technique varies slightly depending on switch type (linear, tactile, or clicky), the core principles remain consistent across guides.
Key findings from the sources:
- Recommended lubricants: Krytox GPL 205g0 for linear switches and TribosSys 3203 for tactile switches are most frequently cited [4][9]
- Critical tools: Switch opener, keycap puller, small brush (2 or 5mm), and tweezers are essential for proper application [3][9]
- Application technique: Thin, even layers on stem rails and housing contact points prevent over-lubrication issues [10]
- Maintenance frequency: Heavy users may need relubrication every 3-6 months, while moderate use extends this to 12 months [8]
Mechanical Keyboard Switch Lubrication Process
Essential Preparation and Tools
Before beginning the lubrication process, gathering the correct tools and preparing your workspace prevents damage to switches and ensures consistent results. The process requires precision instruments and a clean environment, as dust or debris can compromise lubrication quality. Most guides emphasize that proper preparation accounts for 50% of the final outcome's success [3][9].
Required tools with specific recommendations:
- Lubricants:
- Krytox GPL 205g0 for linear switches (most universal recommendation) [4][5]
- TribosSys 3203 for tactile switches (preserves tactility better) [4]
- Krytox 105 oil for springs (3-5 drops per 10-20 springs) [6]
- Application tools:
- 2 or 5mm paintbrush for precise lubricant distribution [9]
- Switch opener (wireform or plastic pry tools preferred to avoid scratching) [3]
- Tweezers with fine tips for handling small components [10]
- Disassembly tools:
- Keycap puller (wire preferred over plastic for durability) [2]
- Switch puller (compatible with your keyboard's hot-swap sockets) [4]
- Soldering station (for non-hot-swappable boards) [8]
Workspace preparation requirements:
- Clean, well-lit surface with ample room for organizing components [9]
- Anti-static mat to prevent electrostatic discharge damage [10]
- Small containers for sorting disassembled switch parts [3]
- Isopropyl alcohol (90%+ concentration) and lint-free cloths for cleaning [8]
Common preparation mistakes to avoid:
- Using excessive lubricant quantities (leads to mushy feel) [5]
- Skipping workspace cleaning (dust contaminates lubricant) [9]
- Using incorrect brush sizes (too large causes over-application) [9]
- Mixing lubricant types on the same switch [4]
Step-by-Step Lubrication Technique
The actual lubrication process follows a systematic approach that varies slightly between switch types but maintains core principles across all varieties. Most comprehensive guides break the process into seven distinct phases, with particular attention to lubricant distribution patterns [3][8].
Disassembly procedure:
- Remove keycaps using a wire puller, applying even upward pressure [2]
- Extract switches using a switch puller (hot-swap) or desolder (soldered boards) [4]
- Separate switch components using a switch opener: - Linear switches: Full disassembly (top housing, stem, spring, bottom housing) [5] - Tactile switches: Leave tactile legs unlubricated to preserve bump feel [4] - Clicky switches: Generally not recommended for lubrication [9]
Lubrication application guidelines:
- Spring lubrication:
- Apply 1-2 drops of Krytox 105 oil to the spring [6]
- Distribute evenly by rolling spring between fingers [2]
- Alternative: Submerge spring in oil briefly then shake off excess [8]
- Housing lubrication:
- Bottom housing: Thin layer on all interior walls where stem contacts [10]
- Top housing: Focus on stem guide rails (avoid metal leaf contact) [10]
- Use brush to apply lubricant in smooth, even strokes [9]
- Stem lubrication:
- Apply to all four rails where stem contacts housing [5]
- For tactile switches, avoid lubricating the tactile legs [4]
- Linear switches benefit from complete stem rail coverage [3]
Reassembly and testing protocol:
- Reassemble switch components in reverse order of disassembly
- Press switch multiple times to distribute lubricant evenly [3]
- Test switch in keyboard before replacing keycap: - Check for smooth actuation without binding [5] - Listen for reduced spring ping and scratchiness [2] - Verify tactility remains intact (for tactile switches) [4]
- Repeat process for all switches, maintaining consistent lubricant amounts
Critical technique considerations:
- Lubricant quantity should create a barely visible sheen - not pooled or dripping [5]
- Over-lubrication causes:
- Mushy bottom-out feel [8]
- Increased actuation force [10]
- Lubricant migration to unwanted areas [9]
- Under-lubrication results in:
- Persistent scratchiness [3]
- Inconsistent smoothness between switches [5]
- Ideal application creates:
- Consistent smoothness across all switches [2]
- Reduced high-pitched spring noise [6]
- Maintained original switch characteristics [4]
