[Prior art]

 As a typical structure of a conventional decorative panel for a switch, as shown in FIG. 4 (A), a portion corresponding to a push button switch of an electric device is printed with a switch type print 21 and has a thickness of about 0.1 to 0.25 mm. The switch portion 22 of the polyester sheet panel 20 is bulged upward by about 0.2 to 0.3 mm by a press, and the back surface thereof is punched to a position corresponding to the switch portion 22 and other display portions. There is a double-sided adhesive tape 24 having a part 23 attached to it.

Further, as a form in which the luxury of the decorative panel is emphasized, (B) as shown in FIG. 5, a through hole 24 is provided in the switch portion by injection molding using acrylic resin as a material, and an arbitrary curved surface is formed. On the lower surface of the panel 25 formed in the above, the switch portion 26 of the molded sheet 27 made of silicon rubber in which the switch portion 26 that fits into the through hole 24 is formed in a protruding shape There is a form in which the boss for screw 28 and the screw 29 or the claw 30 formed on the back surface of the panel 25 are used to press-contact and fix the switch portion of the electric device in the state of being fitted into the.

Further, instead of the molding sheet 27 made of silicone rubber, (C) a plurality of switch portions 31 each having a type printing 21 on the upper surface made of synthetic resin as shown in FIG. The switch part 31 connected to the panel 25 is fitted into the through hole 24 of the panel 25, and the lower surface of the switch part 31 is covered with the silicon rubber packing 34 having the punched part 33 at the gate 32.

[0005]

In the conventional type (A), the processing is easy and inexpensive, and can be applied to a loose quadric surface. The panel is unfamiliar and floats and is not applicable. When the transparent window serving as the liquid crystal display surface is wide, the window is not adhered and floats, so that the panel is distorted and the liquid crystal display appears distorted. Furthermore, since the amount of swelling of the switch part is small, the click feeling is weak and the stereoscopic effect is poor.

In the case of the forms of (B) and (C), a click feeling and a three-dimensional feeling can be obtained, but the panel 25 is formed by interposing the molded sheet 27 made of silicone rubber, the connection switch portion 31 and the silicone rubber packing 33. Since it is necessary to fix the screws with the screws 29 or the claws 30, it is necessary to provide the screw boss 28 or the claws 30 on the back surface of the panel 25. Furthermore, in order to form the acrylic panel on the cubic curved surface. Had the problem that it had to rely on injection molding. Therefore, in order to print a design or characters on the panel 25, in-mold molding is required, resulting in high cost. Although the switch section 30 is structured to be sealed with silicone rubber, there are cases in which troubles occur in terms of waterproofness and dustproof because it is screwed or pressure-contacted and fixed with a claw.

[0007]

[Means for Solving the Problems]

 The present invention solves the above-mentioned conventional problems, and a plate with a three-dimensional appearance can be punched or curved by press instead of injection molding, or a plate made of hard vinyl chloride. This is characterized in that a backing sheet made of polyester or polycarbonate with a swelled switch part is airtightly attached to the back surface of this panel.

That is, according to the present invention, a panel 1 made of polycarbonate or hard vinyl chloride having a thickness of about 1 to 3 mm in which a through hole 2 is provided in a switch portion and a height of the panel 1 fitted into the through hole 2 are formed. Is formed by pressing a switch portion 11 in which the swelling is approximately the same as the thickness of the panel, and a lining sheet 10 made of polyester or polycarbonate and having a thickness of about 0.1 to 0.2 mm. A decorative panel for a switch, characterized in that the other part is adhered and integrated with the switch part 11 of the backing sheet 10 fitted in.
