Third, life and feel are decided by the stroke of the tap switch and the shrapnel, the shorter the stroke, the lighter the sound, the longer the life, the longer the stroke, on the contrary, in the case of fixed shrapnel process, mainly depends on the stroke or sound to decide the life of the tap switch;
In addition, the key factor to determine the life of the shrapnel or stamping technology, before Japan and Taiwan stamping technology is now very popular in the domestic, so in the case of technology improvement, the material requirements are imported materials and then reduced, such as 160gf shrapnel life in the market is mainly four kinds
About 50,000 times (domestic phosphorus copper or relatively backward stamping technology), about 100,000 times, more than 200,000 times (stainless steel)
The assembly process depends on the management ability of the production company, the quality meaning of the staff and the quality assurance ability and other factors. The quality of the final product must be different from that of the different guarantee ability. Now the market assembly method has manual and machine, because the current automation ability is being improved. So each has its advantages and disadvantages: low cost of machine assembly but low quality of products, high cost of manual assembly but high quality. 
The fifth is factory inspection, factory inspection methods and projects also affect the final touch switch quality, such as appearance, feel, conduction, resistance and other projects are sampling inspection or full inspection, such as some big factory requirements of reject rate is PPM to measure or zero defects, it is necessary to set up sampling inspection or quality inspection after the factory inspection.
