外形和冲孔都是薄膜开关的一个组成部分，它们是用专用的机器通过精确度极高的模具压制而成的。

外形和冲孔的形式：

  （1）直角矩形

  （2）圆角矩形

  （3）圆形

  （4）椭圆形

  （5）特殊形

    外形和冲孔的模具全部由我厂用专用模具机制造，精确度高、成本低。

重要的设计考虑因素有哪些？

  （1）薄膜开关要求精度高的，必须用模具

  （2）模具对薄膜开关的价格有影响

  （3）模具精度、形状复杂程度的不同，价格也有所不同

  （4）同种薄膜开关（模具不需重新制造）再次加工时，不需再付模具费

Shape and punch are a part of a thin film switch, which is made by using a special machine with high precision.

Form and punch:

(1) rectangular

(2) rounded rectangle

(3) round

(4) oval

(5) special shape

The shape and punching of the mold all by my factory with special mold machine manufacturing, high precision, low cost.

What are the important design considerations?

(1) thin film switch requires high accuracy, must be used to mold

(2) mold on the price of film switches have an impact

(3) the accuracy of the mold, the complexity of the shape of different, the price is also different

(4) the same kind of film switch (the mold does not need to re manufacture) again processing, do not need to pay the mold fee
