In view of that it could not be detected that the fuze crush switch was welding line and crush switch inner and outer extremely disconnected or virtual welding.This paper presented a nondestructive testing method based on capacitance characteristics of fuze crush switch.The method used capacitance characteristics of the crush switch,through testing capacitance value of the crush switch to determine whether a switch after the en-capsulation assembly welding line and crush switch inner and outer extremely disconnected or virtual welding. Theoretical analysis and measured results showed that the method effectively solved the problem of welding line disconnected,virtual welding of crush switch,and improved the quality of the products.
