摘　　要：本文对墙壁开关按钮卡扣的扣合量对按钮脱扣力的影响进行了研究,首先利用FEA软件计算了按钮的脱扣力,并进行了试验对标。然后分析了不同按钮卡扣的扣合量下按钮脱扣力,并绘制了影响曲线和影响敏感度曲线。最后结合该影响曲线,分析了卡扣扣合量过大和过小按钮脱扣力的不利影响,最后得出卡扣扣合量的经验值0.4 mm是最佳值(在卡扣的接触圆角R为0.2 mm的条件下)的结论。In this article a research was given to the effects of button clip interference of the switch on the button trip force.Firstly,the trip force of the button was analyzed with FEA software and the FEA results were confirmed by the test.Then we compared the button trip forces of switches with different clip interference and drew the effect curve and effect sensitivecurve.Finally according to these curves,the negative effects of excessively big and excessively small clip interference were analyzed.Finally a conclusion wasmade that the experience value of the clip interference,0.4 mm was the best value(in condition that the clip contact radius R is 0.2 mm).
