ことが難しいという不利もある。 However, some parts of this type of rubber switch cover member are transparent or semi-transparent in order to confirm whether the push button switch has been pressed securely and to improve operability in dark places. Increasingly, illuminated type devices are equipped with a light transmitting part and a light source is placed on the back side of the part to provide illumination.
This illuminated type is usually manufactured by molding a colored rubber part and a transparent rubber part separately and gluing them together at a predetermined location, or by molding either a colored rubber part and a transparent rubber part. Because it is made by molding one side, placing it in a mold, etc., and integrally molding it with the other rubber,
The former method requires two types of molds, and this bonding process has the disadvantages of poor yield and unsightly appearance, while the latter method requires two molding processes and requires complicated molds. Both methods also have the disadvantage that it is difficult to form relatively small, finely shaped transparent parts.

A coating film having a cut-out code is applied using a colored paint that adheres to the member, and a peeling part is formed on at least the cut-out code part using a cover member for the switch and a paint that does not adhere to the coating film having the cut-out code, Next, a light-shielding coating layer is applied to the entire surface of the rubber switch cover member, including the peeled part, using a colored paint that adheres to the switch cover member and the coating film having the cut-off code part, and then the peeled part and the peeled part are coated. It is characterized in that a light-transmitting portion is formed by peeling off the upper light-shielding coating layer.

を完成させた。 That is, as a result of various studies on inexpensive industrial manufacturing methods for cover members for rubber switches having a light-transmitting part, the present inventors found that a cover member for rubber switches molded by the conventional method of heating and pressurizing in a mold was developed. First, coat the surface of the key top part of the cover member with a paint that will adhere to this switch cover member so that characters, symbols, etc. of a predetermined size and shape form the cut-out code part, and then apply this coating film to the surface. In order to shield the surrounding irregularities from light, a removable masking layer is formed on the coating film including the cutout code part using a paint that does not adhere to the coating film having the cutout code part, and then this releasable masking layer is formed on the coating film including the cutout code part. If you apply a coating layer with adhesive light-shielding paint on top of the paint layer and then remove this release layer and the light-shielding paint film on this release layer, there will be no paint film on the cut-out code area. It was discovered that the rubber switch cover member having the desired light-transmitting portion can be obtained easily and inexpensively by this method. The present invention has been completed.

で５〜50μmのものとすればよい。 The method of the present invention is to first make characters, figures, etc. through which the light should pass when illuminated, appear as cut-out symbols on the surface of the key top portion of the rubber switch cover member made in this manner. A colored dye with adhesive properties is applied and bonded, but it is sufficient to apply the paint so that it is applied only around these letters and figures, thus forming a light-transmitting area. A mold with characters and figures to be cut out is placed on the section, paint is applied over the mold, and the mold is removed.
This paint is preferably colored black or gray because it has a light-shielding coating film with a cut-out code part, but this coating film may be adhesively fixed to the switch cover member. Therefore, if the switch cover member is made of silicone rubber, it is best to use a silicone-based paint, and if it is made of another type, the surface of the switch cover member made of silicone rubber may be coated with a silicone-based paint. It is best to treat it with a primer or the like in advance.
Note that the thickness of this coating film may be 5 to 50 μm since light-shielding properties are required.

任意のものとすればよい。 The method of the present invention is to apply a paint film that has no adhesive properties to the switch cover member and the coating film having the cut-out code on the coating film having the cut-out code made in this way, and to apply a paint to the cut-out code portion. Masking is applied to form a releasable paint film on this area, and although this paint film adheres to the switch cover member and the paint film with the cut-off symbol, it does not adhere.
It must be easily removable by the method described below, so if the switch cover member and the coating with the cutout code are silicone-based, for example, polyester, acrylic, or polyurethane-based materials should be used. However, since this peeling layer is to be peeled off and removed afterward as described later, the thickness of this layer may be any thickness, for example, from 5 to 300 μm.

のとすればよい。 Next, in the method of the present invention, a coating layer is formed on the removable coating film formed in this way by using a colored paint that adheres to the switch cover member and the coating film with the cutout symbol. This coating layer may or may not be adhered to the above-mentioned releasable coating film, since this releasable coating film is removed by the method described below. In addition, since the paint forming this coating layer is intended to make this rubber switch cover member light-shielding, it is best to use a paint that has excellent light-shielding properties, and therefore has the above-mentioned cutout symbol. Like the paint film, it is preferably black or gray. If the switch cover member is made of silicone rubber, it should be made of silicone like the paint for forming the cutout code, or if it is made of another type, the treated surface should be pretreated. It is preferable to treat the surface with a primer, but since the purpose of this coating is to block light, the thickness of this coating may be 5 to 50 μm.

が与えられる。 The method of the present invention produces a peelable coating film from a cover member for a switch having a coating layer having a bonded and hardened cutout code, a peelable coating film without adhesiveness, and an adhered coating layer obtained in this manner. By removing the coating layer provided on this, a cover member for a rubber switch having a light-transmitting part is obtained. To remove these coatings, for example, remove the coating layer from the top surface with a brush, cloth, or Either remove the coating layer by rubbing it with sandpaper, or dissolve it partially with an appropriate solvent, and then pull out the unadhered release layer from this area and remove it. According to this method, it is possible to obtain the intended switch cover member very easily.

である。 Next, the method of the present invention will be explained based on the attached drawings. Figures 1 to 4 show the method of the present invention in the order of steps, and a in each figure is a top view;
b shows a longitudinal cross-sectional view. In FIG. 1, a colored coating film 6 is applied and fixed on the key top surface of a rubber switch cover member 1 consisting of a key top portion 2, a dome portion 3, and a leg portion 4 to form letters and figures 5 as cutout symbols. Things are illustrated.
Next, as shown in FIG. 2, a peeling layer 7 is provided on the coating film 6 with the cut-out symbol 5 using a paint that does not adhere to the switch cover member 1 and the coating film 6. Further, as shown in FIG. 3, a coating layer 8 is applied and fixed to the switch cover member 1 , a coating film 6 having a cutout symbol, and a light-shielding colored dye having adhesive properties. The method of the present invention involves rubbing the upper part of the switch cover member 1 shown in FIG. When the layer 7 is pulled out, the peeling layer 7 is not adhered to the switch cover member 1 and the coating film 6 with the cutout symbol 5, so it can be easily peeled off. As shown in FIG . 5 is clearly visible from the top, and therefore, when an illumination section is provided below this, the cut-out symbol 5 indicates light transmittance.
