Detailed Answer
Button life is tested per industry standards: the button is pressed continuously at a specified force and frequency until failure, and life should be ≥1 million cycles (consumer) or ≥10 million cycles (industrial grade). The LDER LD series has a button life of 10 million cycles, with tests including: continuous pressing at room temperature, pressing in high/low temperature environments, and pressing with gloves. XINGJIA also implements the 10-million-cycle standard. Button life is related to material and structure: silicone buttons + gold-plated contacts last the longest.
| Industrial grade | ≥10 million cycles |
| Test | Continuous pressing |
| Material | Silicone + gold-plated contacts |
Note:A stiff button with slow rebound signals end of life — replace it promptly.
