Detailed Answer
Key cross-talk (pressing A triggers action B) troubleshooting: 1. Water ingress/moisture (conductive rubber bridges) → dry it; 2. Foreign objects stuck (in key gaps) → clean; 3. Aged/deformed conductive rubber → replace; 4. Circuit board fault (logic error) → factory. Cross-talk is a serious safety hazard (unintended actuation) — stop using immediately and repair. Lider LD series keys have independent circuits + interlock, so cross-talk is rare, but it must be addressed when it occurs.
| Moisture | Dry |
| Foreign objects | Clean |
| Aging | Replace rubber |
Note:Stop using immediately on cross-talk to prevent unintended-actuation accidents.
