Features: 90 million times click life. BT jitter value (Bouncing Test) Based on the optimized internal structure, Kaihua Blue GM 8.0 micro-switch adopts 24K gold contact and grid-like contact method, and has made a breakthrough process for the reed, a series of improvements, which effectively slow down the switch at high frequency. The wear of the contacts caused by the strength tapping keeps the mouse function highly flexible for a long for time. At the same for time, the use of 24K gold improves the conductivity of the switch and the ability to resist oxidation and environmental corrosion. Brand new and high quality Normal strength, crisp hand-free, uniform springback and no hysteresis. The BT jitter value is the physical property of the mechanical switch. The larger the jitter value, the easier it is to issue an error signal, resulting in a double click.
