In order to solve the above problems, the present invention provides a circuit board on which a slide switch is mounted, a case body for housing the circuit board, and a part connected to the slide switch so as to be partially exposed from the case body. A slide switch knob, wherein the slide switch knob is mounted in parallel to the circuit board on the inner surface side of the mounting portion into which the slide switch is inserted and the mounting portion. is formed to have a two protrusions press-fitted held so as to sandwich said slide switch, the case body is characterized by comprising a guide portion defining a movable range of the slide switch knob.

  The present invention relates to an operation switch device for operating, for example, a vehicle instrument that displays vehicle information, and particularly relates to an operation switch device having a slide switch, and even when there is a shift in the mounting position of the slide switch, It is possible to improve the yield in the manufacturing process by allowing the deviation of the mounting position.

  Hereinafter, an embodiment in which the present invention is applied to an operation switch device for performing various operations such as switching or confirmation of various functions in a vehicle instrument will be described with reference to the accompanying drawings.

  FIG. 1 shows an appearance and a sectional view of the operation switch device. The operation switch device mainly includes a switch case (case body) 1, a push button switch knob 2, a switch panel 3, a circuit board 4, and a slide switch knob 5.

  The switch case 1 includes an upper case 1a and a lower case 1b made of a resin material such as ABS, and houses each member constituting the operation switch device. In addition, a guide portion 1a1 that defines a movable range of the slide switch knob 5 is formed in the upper case 1a. Further, the lower case 1b is formed with a wall portion 1b1 that faces the slide switch knob 5. When the slide switch knob 5 moves to the end of the movable range, the slide switch knob 5 comes into contact with the slide switch knob 5. 5 is protected so that an excessive load exceeding the movable range is not applied.

  The push button switch knob 2 is made of light-transmitting acrylic resin, polycarbonate resin, or the like. The push button switch knob 2 is disposed in an opening provided in the upper case 1a, and presses the push button switch 4a mounted on the circuit board 4. It is formed into an operable shape. Further, the push button switch knob 2 may be provided with a function of diffusing the light from the switch illumination LED 4b, for example, by embossing.

  The switch panel 3 is provided on the front side of the upper case 1a, and is formed by a method such as printing with a light-transmitting display design 3a composed of characters, figures, and the like corresponding to the operation function of the operation switch device. . Further, the switch panel 3 is formed with a light emitting display portion 3b for notifying warnings, execution of functions, and the like by light emitting display.

  The circuit board 4 is housed in the switch case 1 and is used to transmit and illuminate the push button switch 4a arranged in accordance with the arrangement position of the push button switch knob 2 and the display design 3a of the switch panel 3. LED 4b for switch illumination, LED 4c for light emission display section illumination for illuminating the light emission display section 3b of the switch panel 3, and a slide switch 4d connected to the slide switch knob 5 are mounted. Further, a wiring pattern is formed on the circuit board 4, and the circuit board 4 is electrically connected via the connection cord A to the vehicle instrument as the operated device. The push button switch 4a and the slide switch 4d are operated by pressing the push button switch knob 2 and sliding the slide switch knob 5, and various operations such as switching or confirming various functions in the vehicle instrument are executed.

  The slide switch knob 5 is made of a resin material such as ABS, and the operation unit 5a is disposed so as to be exposed from the switch case 1, and the user slides the operation unit 5a in the vertical direction in FIG. The slide switch 4d mounted on the circuit board 4 can be operated. The slide switch knob 5 has a concave regulating portion 5b that is fitted into a guide portion 1a1 formed in the upper case 1a.
