How to Prevent Contact Failure Under High Vibration in Aerospace Switches
Author: Postek Engineering Team | Reading time: 12 minutes | Application: Aerospace Introduction In aerospace and mission-critical applications, switches are frequently subjected to vibration levels exceeding 50G at frequencies up to 2000Hz — conditions that would cause standard commercial switches to fail within minutes. Under these conditions, contact bounce, intermittent signal loss, and complete contact failure become real threats to mission safety. This article examines the root causes of vibration-induced contact failure, the engineering standards that define acceptable performance, and the design features of hermetically sealed micro switches that enable reliable operation in the most demanding aerospace vibration environments. ...
