摘要： The object of the present invention is to provide a method of manufacturing a member for push-button switch having key top members positioned close to each other through a distance of 1.5 mm or shorter at low cost and with high yielding.
Thereby, the member (1) for push-button switch to be manufactured by the method of the present invention comprises a plurality of key top members (2) having resin key top cores (21) and thermoplastic films (22) covering the key top cores (21) other than the lower surfaces thereof. The key top members (2) are further so formed that an interval between at least one set of adjacent key top members (2) among the key top members (2) is 1.5 mm or shorter, the maximum thickness (t0) of the thermoplastic films (22) covering the key top cores (21) being within the range of 75 to 350 µm. Accordingly, the method of manufacturing such a member for push-button switch (1) comprises a forming step (S1; S11; S21) of stretching the thermoplastic film (22) having a temperature from 135 to 145 °C according to the shape of a mold (40, 51) thereby forming the thermoplastic film (22) to a size enough to cover a plurality of adjacent key top cores (21), an integration step (S2; S12; S22) of integrating the plurality of adjacent key top cores (21) with the formed thermoplastic film (22) thereby making a key top member body (23), an arrangement step (S3; S14; S24) of arranging the key top member body (23) or the key top member (2) on a base member (3) for pressing the switch, and a separation step (S4; S15; S23) of separating the key top member body (23) into the units of key top members (2).
摘要翻译：本发明的目的是提供一种制造按钮开关的构件的方法，该按钮开关的构件具有以低成本和高产量彼此靠近彼此定位1.5mm或更短的距离。因此，通过本发明的方法制造的按钮开关用构件（1）具有多个具有树脂键顶芯（21）的键顶构件（2）和覆盖键顶的热塑性薄膜（22）除了其下表面之外的芯（21）。键顶构件（2）进一步形成为使得键顶构件（2）中的至少一组相邻的键顶构件（2）之间的间隔为1.5mm或更短，热塑性塑料的最大厚度（t0）覆盖键顶芯（21）的膜（22）在75〜350μm的范围内。因此，制造这种按钮开关（1）的构件的方法包括：根据形状步骤（S1; S11; S21），将具有135至145℃温度的热塑性薄膜（22）模具（40,41），由此形成足够覆盖多个相邻键顶芯（21）的尺寸的热塑性薄膜（22）;积分步骤（S2; S12; S22），其将多个相邻键顶具有形成的热塑性膜（22）的芯（21），由此形成键顶构件主体（23）;布置步骤（S3; S14; S24）将键顶构件主体（23）或键顶构件）和用于按压开关的基部构件（3）上，以及分离步骤（S4; S15; S23），将键顶构件主体（23）分离成键顶构件（2）的单元。

摘要： A key top member (10) for a push button switch structure capable of facilitating change and modification of a design while eliminating deformation and misregistration of a display section, being accommodated to a variety of data, being increased in design properties and visibility, and being reduced in manufacturing cost. An upper resin sheet (2) made of thermoplastic resin and having display sections (1) such as a letter, a symbol, a pattern or the like printed thereon is formed with projections (3) having configurations conforming to outer configurations of key top elements. The projections (3) are each securely provided therein with a filler member (5) made of photosetting resin directly or through an adhesive.
