Embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
As shown in figure 1, a kind of fool proof dual sense button of the utility model, the button is set outside interior successively
There are circuit board 10, metal clips 20, capacitive sensing layer 30, the middle part of the metal clips 20 is provided with arc convex, and the arc is convex
Rise and form deformation gap between the circuit board 10；Current detecting is provided between the metal clips 20 and the circuit board 10
Module 50, capacitive detection module 60 is provided between the capacitive sensing layer 30 and the metal clips 20；Pressed by conductive body
When pressing button, the capacitance between the capacitive sensing layer 30 and the metal clips 20 produces change, the capacitance detecting mould
Block 60 produces capacitance detecting signal；Also, the arc convex of the metal clips 20 due in the presence of pressing force concave change shape with
Electrical connection is produced between the circuit board 10, the current detection module 50 produces current detection signal.
In the present embodiment, the outside of the capacitive sensing layer 30 is additionally provided with protective layer 40, and the protective layer 40 is used and is coated on
Protection glue-line on the capacitive sensing layer 30 or the protection film layer being bonded with the capacitive sensing layer 30；For example, the guarantor
