The present invention relates to a method of manufacturing a cover member for a rubber switch, which is useful for, for example, an in-vehicle telephone, various push-button switches for in-vehicle use, or push-button switches for dark places.

いという不利もある。However, some parts of this type of rubber switch cover member are transparent or translucent in order to confirm whether the push button switch has been pressed and to improve operability in dark places. Increasingly, illuminated type products are equipped with a light transmitting part and a light source is placed on the back of the part to provide illumination.However, these type of illuminated products are usually manufactured by separating the colored rubber part and the transparent rubber part. Either the colored rubber part or the transparent rubber part is molded, and then it is placed in a mold and molded integrally with the other rubber part. The former method requires two types of molds, and this bonding process has the disadvantages of poor yield and an unsightly appearance; the latter method requires two molding steps. These methods also have the disadvantage that it is difficult to form relatively small, finely shaped transparent parts in each case.

A coating film with a cut-out code is applied using a colored paint that adheres to the cover member, and a peeling part is formed on this using a switch cover member, a paint film with a cut-out code, and a non-spraying paint, and then After coating a light-shielding coating layer on the peeled part with a colored paint that adheres to the switch cover member and the coating film with the cutout code, this peeled part and the light-shielding coating layer on the peeled part are peeled off to allow light to pass through. It is characterized by forming a section.

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 inventors of the present invention have developed a rubber switch molded by a conventional method of heating and pressing in a mold. First, paint that adheres to the switch cover member is applied to the surface of the key top part of the switch cover member so that letters, symbols, etc. of a predetermined size and shape become cut-out symbols, and this coating film is coated on the surface. In order to shield the surrounding unevenness from light (2), we used a paint that does not adhere to the coating film with the cut-out code part (2) on this coating film containing the cut-out code part (
Two removable masking layers are formed, and then a coating layer of 98% is applied on this removable middle film J→ with an adhesive light-shielding agent, and then this removable layer I and the light-shielding coating on this releasable layer are formed. It was discovered that if the film is removed, no coating film remains on the cut-out code part, which imparts light transparency to it. According to this, light transmission can be easily and inexpensively produced on its own. The present invention was completed by confirming that a cover member for a rubber switch having a sexual part could be obtained.

コーンゴム製とすることがよい。The switch cover member itself constituting the rubber switch cover member having the illumination part of the present invention may be made by a known method. These rubbers are made of natural rubber, diene-based synthetic rubbers such as polybutadiene, polyisoprene, SBR, and neorene, synthetic rubbers such as ethylene-propylene-based, urethane-based, polyester-based, and silicone-based, or synthetic rubbers such as these. It may be made from a combination of silicone rubber, which has good transparency, heat resistance, weather resistance, and electrical insulation (as the illumination part must be transparent or semi-transparent). It is good to do.

A colored dye that has adhesive properties is applied to the parts and adhered to them, but it is enough to place the paint so that the paint is applied only around these letters and figures, and therefore this is the part that forms the light-transmitting part. (C2) Place a mold with characters and figures to be used as double-crossed symbols, apply room material over the mold, and remove the mold.

を予じめプライマーなどで処理しておくことがよい。This paint is preferably colored black or gray because it has a light-shielding coating film with cut-out code parts, 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 silicone-based paint, but if it is made of another type (=
It is preferable to treat the surface of this silicone rubber switch cover member with a primer or the like in advance.

A removable coating film is formed on this part by masking the part, but this coating film adheres to the switch cover member and the coating film with the cutout symbol, but does not adhere to it, as will be explained later. method, etc. (=Therefore, it must be easily removable, so if the switch cover member and the coating with the cutout symbol are silicone-based (for example, polyester, acrylic, or polyurethane-based) However, since this peeling layer is to be peeled off and removed afterward as described later, the thickness of this layer may be set to an arbitrary thickness of, for example, 5 to 300 μm.

ればよい。Next, in the method of the present invention, a coating layer is formed on the removable wall film formed in this manner to cover the switch cover member and the coating film having the cut-out symbol using a colored material that adheres to the coating film. However, this coating j- has the above-mentioned releasability of 4[
Since this releasable coating film is removed by the method described below, it may or may not be adhered to this. 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, the coating layer with the above-mentioned cutout symbol is used. Similarly, it is best to use black or gray. If the switch cover member is made of silicone rubber, it should be made of a silicone-based material 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 .mu.m.

ができるという有利性が与えられる。The method of the present invention produces a peelable paint film from the switch cover member having the adhesive-hardened paint film layer with the cutout code, the non-adhesive peelable wall film, and the bonded coating layer thus obtained. 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 wall films, for example, the upper surface of this product is removed using a brush, cloth, or sandpaper. Either remove the coating layer by rubbing it with a tool, or dissolve it partially with a suitable solvent, and then pull out the unadhered release layer from this area and remove it. Accordingly, there is an advantage that the intended switch cover member can be obtained extremely easily.
