Abstract

The text discusses the failure issues of the YBLXW-5 series micro switch concerning mechanical, electrical, and heating aspects, thoroughly investigating the contact bounce phenomenon and its structural optimization methods. By establishing statics and dynamics models, the dynamic characteristics of bounce were analyzed, and finite element simulation along with genetic algorithms was used to optimize structural parameters. The research results indicate that the optimized micro switch's bounce time decreased by 32.04%, and the maximum bounce amplitude reduced by 55.97%, significantly enhancing dynamic performance and contact reliability. This study provides a theoretical basis and practical guidance for the structural optimization and performance improvement of micro switches, which is of great significance for their stability, reliability, and safety in actual applications, while also promoting the development and application of micro switch technology.
