Title  The Design of Fatigue Life Test of a Kind of Device Button Switch       

Abstract Button switch has wide application on control system,and its operation reliability has important effect an system.Based on mechanical design theory,measurement technology and other related knowledge,a detection device with one working postion for fatigue life check of button switch was designed.Firstly,the basic requirements of the device was analysed,and the overall design of the device was carried out.Secondly,the champing system,driving system,measurement system,controlling system were designed respectively.The corresponding 3D modeling of the designed mechanical system and portical 2D engineering drawings were completed.The control system was conducted by VB.The button switches of different kinds of types could be clamped,pressed an checked on the designed device.The checked data could be displayed on the designed device.The checked data could be displayed on the device.The designed device has some engineering value.
