Order line Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The adhesive is heated to harden the adhesive 4 0 0 and the second wiring substrate 20. Then, the second wiring substrate is used to form the first wiring substrate board 20 by screen printing silver paste, and the second 5. 5 is coated (filled) in the perforations 24. By using the second conductive material 2 5 to reach the first conductive pattern for LED 14 (the first connection 14a), the second LED conductive pattern 14 is electrically connected to the conductive layer formed by applying silver paste. Adhesive 5 Electrically conductive adhesive 5.1 and second conductive resin 5 2 to cover the LED. Finally, the shape-improved contact 90 is held in advance on the predetermined wiring substrate 20 and becomes a push-type switch of the present invention. The sheet-shaped switch of the substrate is described as the upper wiring board (the second switch section. At this time, the holding sheet and the wiring board system do not need to be a rigid substrate. It is also conductively connected. Bonding with sex 1 In the above, the electrical material 2 5 0, the point 9 0 of the construction and borrowing position is the same as the pattern 2 3 at the same time, and the agent 5 1 at the same time. By heating 5). The near-ultraviolet coating on the lower holding sheet 3 is stored in the case and the first L. After the alley, after drying the silver in the future, the coating line makes the hard surface adhere to 0, and the opening 2 is shown to have two The switch unit may be bonded to the one wiring-based flexible insulating substrate by using one of the wiring substrates 20) and one wiring 30, but paper may also be used for the second fixed fixing portion ED 2 3b LED paste (conducting enhancement. The agent can be used in the second 2. The wiring is used as a board except for the substrate. The phenol substrate has fixed contacts. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ) -18- 480505 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the Invention (16) As a C-shape, there is no perforated wiring board in the center of the first fixed contact. This At this time, the adjustment layer is used as a photoresist layer, which is formed on the conductive pattern drawn from the first fixed contact. The adjustment layer can adjust the click sound and prevent the first fixed contact and movable when not operating. The contact becomes a disadvantage of continuity. (Result) The push-type opening relationship of the present invention includes a wiring substrate provided with a fixed contact formed by a first fixed contact and a second fixed contact, and a metal formed in a dome shape that often contacts the second fixed contact. When the central part of the movable contact is pressed, the stroke of the central part of the movable contact is reversed by a predetermined stroke amount to a state in which it is in contact with the first fixed contact part, and the stroke amount of the movable contact is adjusted. The adjustment layer is provided on the above-mentioned wiring substrate, and at the same time, a part of the movable contact is placed on the adjustment layer. Therefore, it is not necessary to change the movable contact itself, and the stroke amount or click force can be adjusted, and only one movable contact can be used. Different switches with a click sound are obtained. In addition, since the adjustment layer is configured to be provided on the second fixed contact formed on the wiring substrate, when the fixed contact is formed by printing, the film thickness may vary. However, because the adjustment layer is set on the second fixed fixed contact, the film thickness deviation of the fixed contact is absorbed, which does not easily affect the stroke amount or the click force. Therefore, even at the fixed contact film thickness When the film thickness is generated, a push-type switch that is less likely to have variations in characteristics can be provided. In addition, since the adjustment layer is made of a photoresist layer made of a thermosetting resin, the adjustment layer can be made relatively hard, so Applicable to China National Standard (CNS) A4 (210 x 297 mm) for long-term paper sizes -19-

480505 A7 ____ B7 V. Description of the invention (17) The use also rarely changes, and the desired stroke amount can be maintained for a long period of time. In addition, when used for a vehicle and exposed to high temperatures, the characteristics of the adjustment layer do not change much even though the adjustment layer becomes soft. In addition, the adjustment layer system has a structure formed by a conductive layer of a bonding resin comprising conductive particles dispersed in a thermosetting resin. The adjustment layer can be made harder. Therefore, the usage is rarely changed over a long period of time, and the desired stroke amount can be maintained over a long period of time. In addition, when used in a vehicle and exposed to high temperatures, the characteristics of the adjustment layer do not change much even though the adjustment layer becomes soft. In addition, the adjustment layer can be made of the same material as the pattern of the fixed contact by forming the conductive layer, and can provide a push switch with improved productivity and low cost. In addition, the fixed contact is formed on one surface of the substrate body constituting the wiring substrate, and the wiring substrate has a conductive pattern on one surface and the other surface of the substrate body. The conductive material in the inner hole of the fixed contact is connected to the conductive pattern on the other side. The second fixed contact is formed by the conductive pattern on the one side. Therefore, the adjustment layer is prevented from being connected to the first fixed contact. The conductive pattern of dots can improve the design freedom of the adjustment layer. Printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The adjustment layer is formed by printing on the wiring substrate. The adjustment layer can be formed at each fixed contact at a time. Therefore, when multiple switches exist on the same substrate, each can be suppressed. The characteristics of the switches vary, and mass productivity is good.
