Mouse Drag Test
Diagnose switch contact dropouts and micro-release chatter during sustained click-and-drag movements.
Click & Hold to Test Contact
Press and hold the selected button, then drag across the surface to detect micro-dropouts and spring leaf chatter under physical movement.

2 Logitech Lightforce (Superlight 2 / G502X)Hybrid Optical | Optical + Mechanical Leaf | Continuous Hold | < 0.05% (Hybrid Reliability) | Tier S (Hybrid Hold) |
3 Huano Blue Shell Pink Dot (Zowie / VAXEE)High-Tension Mechanical | Firm Leaf Spring | Stable Hold | < 1% (Low Dropout Risk) | Tier B (Stiff Tension) |
4 Generic Aged Omron 20M / 50MFatigued Spring Leaf | Weakened Copper Spring | Vibration Sensitive | > 25% (High Dropout Risk) | Tier D (Frequent Dropout) |
Understanding Mouse Switch Dropouts & Contact Fatigue
What is a Switch Dropout?
Hardware FaultA dropout occurs when an oxidized or mechanically degraded micro-switch momentary interrupts electrical contact for 10ms–100ms while your finger is firmly pressing down on the shell plunger.
Real-World Symptoms
Desktop & GamingSymptoms include prematurely dropping dragged desktop files into unintended folders, unintentional weapon un-scoping in tactical shooters, or breaking drag-select selection boxes.
Leaf Spring Tension Fatigue
Mechanical WearOver millions of actuations, the internal copper/gold alloy leaf spring loses curved spring tension. When applying light steady pressure, micro-vibrations break mechanical continuity.
Optical Switch Solution
Dropout ResistantOptical micro-switches replace mechanical leaf contact leaves with an infrared light beam sensor. As long as the physical shutter blocks the light beam, the signal remains continuous with near-zero risk of mechanical chatter dropouts.
