and high quality. 80 million times click life. Normal strength, crisp hand-free, uniform springback and no hysteresis. BT jitter value (Bouncing Test): 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. Based on the optimized internal structure, for GM 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.
