[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-color illuminated pushbutton switch structure used in electronic equipment.

[0002]

[Prior Art]

 4 and 5 show a key switch structure as a conventional push button switch structure. In this key switch structure, a movable contact member 42 having a spring-like property that is bent in a dome shape and is inverted when the center is pushed down, and the movable contact member 42 is disposed so as to be dropped and arranged on the bottom surface. A resin case formed by arranging a first fixed contact member 44 and a pair of second fixed contact members 45 on which the peripheral edges of the movable contact member 42 are placed and are in constant contact with each other. 43, a cover 46 arranged so as to close the upper surface opening of the case 43, and a case 43 which partially penetrates through the through hole 47 of the cover 46 and is arranged on the movable contact member 42 in the case 43. And a push button 48 that can be pressed from the outside.

The push button 48 is normally displaced upward by the spring force of the movable contact member 42 until the retaining portion 48 a provided inside the case 43 hits against the lower surface of the cover 46 and is restricted. ing. As a result, the central portion of the movable contact member 42 and the first fixed contact member 44 are also separated from each other as shown in FIG. 5, and the first fixed contact member 44 and the second fixed contact member 45 are not separated from each other. It is in a conducting state.

On the other hand, when the push button 48 is pushed down, the central portion of the movable contact member 42 is pushed by the push button 48 and elastically deforms, and the movable contact member 42 is inverted. The movable contact member 42 makes common contact with the first fixed contact member 44 and the second fixed contact member 45, and the movable contact member 42 is provided between the first and second fixed contact members 44, 45. Is conducted through. When the push-down force of the push button 48 is released again, it is reversed by the self-returning force of the movable contact member 42 and returns to the original state.

[Problems to be solved by the device]

 As described above, in the conventional example, the light emitting diode is not built in, and therefore, there is a problem that it is not possible to cope with the switch display.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a push button capable of coping with the switch display and reducing the cost. It is to provide a switch structure.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention inserts a push button in a case, and inserts a plurality of light emitting diodes inside the push button so that the horizontal portion of the terminal leg of the light emitting diode becomes a push button. Insert it into the formed leg insertion groove, insert the vertical part of the terminal leg into the leg insertion groove of the case, insert the mechanical key switch into the case, and insert the locking protrusion of the locking piece of the case into the mechanical key switch. It is characterized by being locked to the lower edge of the side part.

[0008]

[Action]

 Due to the built-in structure, multiple light-emitting diodes are built in to eliminate uneven brightness and color, improve quality, and cope with switch displays.The mechanical key switches and light-emitting diodes in the case can be used as they are. Since it is built-in, the cost can be reduced.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially sectional plan view of the present invention. The push button switch structure according to the present invention comprises a case 1, a push button 2 integrally formed with a cap 5, a mechanical key switch 3, and two light emitting diodes 14.

The case 1 is provided with a plane main body 4 having a square shape. The case main body 4 has an upper surface and a lower surface opened, and the left and right side surfaces 4 a and 4 b have lower edges. The notches 15 are formed, and the engaging pieces 6 are formed at the edges of the notches 15, and the engaging protrusions 6a projecting inward are formed at the tips of the engaging pieces 6. There is. In addition, a leg insertion opening 7 is formed in the longitudinal direction at the center of the inner surface of the front and rear side surfaces 4c, 4d of the case body 4.

The push button 2 is provided with a white and hollow button body 8, a cap device portion 9 is formed on the upper portion of the button body 8, and the button body 8 has an intermediate portion to a lower end portion. The lower end portion is formed into a contact portion 10, and the button body 8 is formed with two leg insertion groove portions 11 from the contact portion 10 to the middle portion. A guide block 12 is formed at each corner of the main body 8. The cap 5 is attached to the cap device portion 9 of the button body 8.

The mechanical key switch 3 includes a movable contact member (not shown) having a dome-shaped curved spring property that is inverted when the central portion is pushed down, and the movable contact member is arranged so as to be dropped and the bottom surface. A first fixed contact member (not shown), which is placed opposite to the movable contact member, and a pair of second fixed contact members (Fig. A resin case 18 formed by arranging (not shown) and a push button portion 19 are unitized.

Further, the light emitting diode 12 is provided with two left and right terminal leg portions 17, and the terminal leg portions 17 are bent at a right angle in the middle thereof.

Then, the push button 2 is inserted into the case 1, and the upper edge of the guide block 12 of the push button 2 is brought into contact with the edge of the corner of the case 1 to form a stopper. Then, the light emitting diode 14 is inserted into the lower portion of the push button 2, the horizontal portion 17a of the terminal leg portion 17 is inserted into the leg insertion groove portion 11, and the vertical portion 17b of the terminal leg portion 17 is inserted into the leg insertion groove 7 of the case 1. insert. Next, the mechanical key switch 3 is inserted into the case 1, and the locking projection 6a of the locking piece 6 of the case 1 is locked to the lower side edge of the mechanical key switch 3 to form a push button switch structure. There is.

Next, the operation will be described. When the push button 2 is pushed, the push button portion 19 of the mechanical key switch 3 is pushed by the contact portion 10 below the push button 2 to activate the mechanical key switch 3. In this case, since the horizontal portion 17a of the terminal leg portion 17 of the light emitting diode 14 is inserted in the leg insertion portion 11 of the push button 2, the light emitting diode 14 does not move with respect to the movement of the push button 2.

When the push button 2 is pressed once, one light emitting diode 14 is turned on, and when the push button 2 is pressed a second time, the other light emitting diode 14 is turned on.

[Effect of the device]

 As described above, according to the present invention, the pushbutton is inserted into the case, and the plurality of light emitting diodes are inserted inside the pushbutton to form the horizontal portion of the terminal leg of the light emitting diode into the pushbutton. Insert the vertical part of the terminal leg into the leg insertion groove of the case, insert the mechanical key switch into the case, and insert the locking protrusion of the locking piece of the case into the bottom of the mechanical key switch. Since the push button switch structure is configured to be locked to the edge, the built-in multiple light emitting diodes eliminates brightness and color unevenness, improves quality, and can handle switch displays, and Since the mechanical key switch and the light emitting diode are built in as they are, the cost can be reduced.
