Prevent dual response button of maloperation

The utility model discloses a prevent dual response button of maloperation, be equipped with circuit board, metal shrapnel, electric capacity inductive layer outside the button follow is interior in proper order, metal shrapnel's middle part is equipped with the arc arch, this arc protruding with form between the circuit board and warp the clearance, metal shrapnel with be equipped with current detection module between the circuit board, the electric capacity inductive layer with be equipped with capacitance detection module between the metal shrapnel, when pressing the button through conductive body, the electric capacity inductive layer with capacitance value between the metal shrapnel changes, capacitance detection module produces the electric capacity detected signal, furthermore, therecessed deformation of effect of the protruding because pressing force of metal shrapnel's arc with it connects to produce the electricity between the circuit board, the current detection module generate current detected sig
