外形和沖孔都是薄膜開關的一個組成部分，它們是用專用的機器通過精確度極高的模具壓制而成的。

外形和沖孔的形式：

  （1）直角矩形

  （2）圓角矩形

  （3）圓形

  （4）橢圓形

  （5）特殊形

    外形和沖孔的模具全部由我廠用專用模具機制造，精確度高、成本低。

重要的設計考慮因素有哪些？

  （1）薄膜開關要求精度高的，必須用模具

  （2）模具對薄膜開關的價格有影響

  （3）模具精度、形狀復雜程度的不同，價格也有所不同

  （4）同種薄膜開關（模具不需重新制造）再次加工時，不需再付模具費

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
