For 5G communication devices, which require miniaturization and high reliability, the switch packaging must feature high stability, high heat resistance, and high impact resistance. In response, we have developed ultra-thin, compact membrane switches that also significantly contribute to reducing the design space of PCBs. With a lifespan design of over 500,000 cycles and an IP67/68 dustproof and waterproof design, these switches meet all the requirements of 5G communication equipment.
