new 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 micro-switch adopts 24K gold contact and grid-like contact method, and has made a breakthrough process for the , a series of improvements, which effectively the switch at high frequency. The wear of the contacts caused by the strength tapping keeps the mouse function highly flexible for a long . At the same , the use of 24K gold improves the conductivity of the switch and the ability to resist oxidation and environmental . Name:for 8.0 Mouse Micro-type Switch Life:80 million times click Material and structure: 24K gold contacts and grid-like contact Quantity:10Pcs Color:As Shown Material:plastic Package Contents: 10 * Mice Micro-type Switch Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
