Research on Endurance Environmental Design Method of Travel Switch for Aerospace Applications
The limit switch,also known as the position switch,is a common microcurrent control device.Its main function is to activate the internal mechanical structure to drive the contacts and thereby connect or disconnect the control circuit,achieving the desired operational effect when external force acts on the operating lever of the device.The elastic connection between the contacts and contact tips of this switch can be affected by vibrations,impacts,or continuous acceleration,affecting the stability of the contact between the contacts.As this contact mechanism is a crucial link in the current conversion of the microswitch,contact stability is essential to the performance of the switch.When exploring the durability of the limit switch,it is necessary to delve deeply into factors such as the natural frequency of the contact system,the amplitude characteristics of vibration response,and contact force.In dynamic environments,these variables may exhibit nonlinear patterns of change.Through in-depth research,we can better understand the working performance of the limit switch in complex environments,thus providing theoretical support for its optimized design and improved durability.
