To lubricate custom mechanical keyboard switches—specifically tactile switches—without dulling their tactile bump or creating mushy keystrokes, apply a medium-low viscosity grease like Tribosys 3203 to the stem side-rails and housing slider tracks at a 1:1 ratio, strictly avoiding the stem legs. Bag-lube 100 springs simultaneously using 8 to 10 drops of Krytox GPL 105 High-Viscosity Oil inside a sealed polythene bag for 120 seconds to eliminate spring ping completely.
Section 1: Required Tools & Material Specifications
Before disassembling custom switches, gather these exact enthusiast-grade tools and chemical lubricants to guarantee acoustic consistency and avoid component damage:
- Tactile Stem & Housing Lubricant: Tribosys 3203 (Grade 0 fluorinated grease with medium-low viscosity).
- Spring Lubricant: Krytox GPL 105 High-Viscosity Synthetic Oil.
- Switch Opening Tool: Universal 4-Prong Aluminum Switch Opener (Kailh & MX compatible).
- Precision Applicator Brush: Size #00 Fine Point Synthetic Nylon Detail Brush.
- Housing Sealers: 0.125mm HTV/PC Dual-Layer Switch Films.
Section 2: Executive Specification, Ratio, & Operating Parameters Matrix
| Processing Stage | Required Material / Compound | Exact Ratio / Measurement | Operating Temp (°F/°C) | Duration / Timing | Critical Hazard / Pro-Tip |
| 1. Switch Disassembly | 4-Prong Switch Opener | N/A | Ambient | 10 Sec / Switch | Apply vertical pressure only to prevent snapping housing clips. |
| 2. Spring Bag-Lubing | Krytox GPL 105 Oil | 8 – 10 Drops per 100 Springs | Ambient | 120 Seconds (Shake) | Ensures 100% uniform oil coverage without messy manual brushing. |
| 3. Tactile Stem Lubing | Tribosys 3203 Grease | Micro-thin glaze (Brushes appear dry) | Ambient | 30 Sec / Stem | NEVER lube stem legs. Lube on legs eliminates the tactile bump. |
| 4. Housing Track Lubing | Tribosys 3203 Grease | 1 light pass on slider rails | Ambient | 15 Sec / Housing | Avoid pooling grease in the bottom center stem well. |
| 5. Film & Reassembly | 0.125mm Polycarbonate Film | 1 Film per switch housing | Ambient | 15 Sec / Switch | Aligns top/bottom housing to eliminate housing wobble and deepen sound profile. |
Section 3: Practitioner Protocol: Step-by-Step Execution Workflow
- Deconstruct Switch Assemblies: Place the target switch on a universal MX/Kailh switch opener. Press down firmly until the side latches release. Separate the Top Housing, Bottom Housing, Spring, and Stem into a 4-compartment lube station tray.
- Execute Mass Spring Bag-Lubing: Place 100 dry switch springs into a clean polythene bag. Add 8 to 10 drops of Krytox GPL 105 oil directly into the bag. Trap air inside the bag, seal it tightly, and shake vigorously for 120 seconds. The oil will coat every spring coil evenly without pooling.
- Apply Tactile Stem Coating: Dip a #00 fine brush into Tribosys 3203 grease. Wipe off excess lubricant against the container wall until the brush bristles appear nearly dry. Paint a paper-thin layer along the two side-rails of the stem. Crucial: Keep the two protruding tactile legs 100% dry.
- Glide-Rail Bottom Housing Detail: Lightly stroke the internal left and right slider rails of the bottom housing with the remaining lubricant on your brush. Do not let grease collect in the bottom center hole.
- Film Placement & Clip Reassembly: Seat a 0.125mm HTV/PC switch film onto the bottom housing rim. Reinsert the oiled spring, place the lubricated tactile stem inside, align the top housing, and snap the housing clips together securely.

TACTILE SWITCH LUBRICATION & MODDING WORKFLOW CHECKLIST
====================================================================
Project Name: ___________________ Date: August 8, 2026
Switch Count: [ ] 60% (61) [ ] TKL (87) [ ] Full-Size (108)
[ ] STEP 1: Disassemble switches using 4-prong opener into sorting tray.
[ ] STEP 2: Add 100 springs + 10 drops Krytox GPL 105 to bag; shake 2 mins.
[ ] STEP 3: Apply Tribosys 3203 to Stem side-rails with #00 brush (SKIP LEGS).
[ ] STEP 4: Lightly coat bottom housing slider tracks (Avoid center well).
[ ] STEP 5: Align 0.125mm switch film over bottom housing perimeter.
[ ] STEP 6: Reassemble switch; test actuation force & tactile bump response.
====================================================================
Section 5: Common Execution Mistakes & Material Damage Prevention
- Over-Lubing the Tactile Stem Legs: Applying thick grease like Krytox 205g0 or Tribosys 3203 directly to the tactile legs dampens the leaf spring interaction. This turns a crisp tactile switch into a mushy, heavy linear feel. Prevention: Keep the front legs 100% dry.
- Excess Grease Pooling in Stem Well: Applying too much lubricant to the bottom housing causes fluid to pool in the center hole. When pressed, this creates an annoying hydraulic “pop” or “sloshing” sound. Prevention: Use a dry microfiber cloth to wipe the center well if grease accumulates.
- Deforming Housing Latches: Forcing switches open with flathead screwdrivers bends the plastic latches, leading to loose top housings and rattle. Prevention: Always use a dedicated aluminum 4-prong switch opener.
Section 6: Quality Inspection & Verification Checkpoints
- Preserved Tactile Bump: Depressing the switch slowly reveals a sharp, defined tactile bump near the top of the keypress with zero mushiness.
- Zero Spring Ping: Tapping the reassembled switch rapidly near your ear produces clean bottom-out acoustics with zero metallic spring ping or crunch.
- Smooth Travel Action: Pushing the stem down off-center yields smooth scratch-free travel without binder-friction feeling.
Section 7: Essential Recommended Equipment & Supplies

- [Required Tactile Lube Spec]:Tribosys 3203 Grade 0 Switch Lubricant (Medium-Low Viscosity)
- [Required Spring Lube Spec]:Krytox GPL 105 High-Viscosity Synthetic Lubricant Oil
- [Required Modding Tool Spec]:KBDfans Mechanical Switch Opener & Stem Holder Kit
