Features: Normal strength, crisp hand-free, uniform springback and no hysteresis. Life: 80 million times click Material and structure: 24K gold contacts and grid-like contact. Quantity: 4Pcs 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, Kaihua 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. Package includes: (Without retail package) 4 x Original Kailh for GM 8.0 Mouse Micro Switch
