Detailed Answer
Not necessarily. The higher the protection rating, the higher the cost, and heat dissipation and key feel may be affected. Selection principle: match the actual environment — IP54/IP65 is enough for a clean indoor workshop, IP65/IP66 for outdoor, IP67/IP68 for ports and shipyards. IP67 on the LIDER LD series is the sweet spot for cost-effectiveness; the XINGJIA Xingdun IP68 suits extreme environments. Over-specifying wastes budget; under-specifying leaves safety hazards.
| Principle | Match the environment |
| Balanced | IP67 |
| High-end | IP68 as needed |
Note:List your environmental conditions first, then set the protection rating — don't blindly chase the highest.
