One kind of new micro acceleration switch’s structure and the principle of work are proposed

and this organization’s high overload capacity is analysed.The size parameter design formula which has satisfied the high overload condition is obtained.The organization parametrization mathematical model is established.This organization system-level modeling and simulation are carried on according to the mathematical model.The relational curve between displacement and the time is obtained.The simulation result shows that this micro acceleration switch has validity and feasibility in satisfing the high overload condition with the switch function.
