This invention is a car stereo, 8mm
The present invention relates to a push button switch used as a consumer device, such as a video, and more particularly, to a thin lateral push type push button switch.

2. Description of the Related Art In recent years, as electronic devices have become lighter and thinner, there has been a demand for smaller and thinner switches themselves. Such a conventional push button switch is disclosed in Japanese Utility Model Laid-Open No. 1-16993.
No. 5 is known. FIG. 5 shows this conventional push-button switch, in which fixed contacts 2 and 3 are provided on the inner bottom surface of the housing 1.
A movable contact 4 capable of reversing the curvature is provided on the upper side, and the movable contact 4 is mounted on the fixed contact 3. A rotating member 5 is disposed above the movable contact 4, and the pressing projection 6 for pressing the movable contact 4 provided on the rotating member 5 does not operate the stem 7. A pressing plate 8 is provided on the upper surface of the housing so as to prevent the above members from coming off. When the stem 7 is pressed under the above configuration,
The upper part 9 of the rotating member 5 is pressed, whereby the pressing protrusion 6 rotates downward about the support shaft 10 as a fulcrum. Therefore,
The movable contact 4 comes into contact with the fixed contact 2 and the switch is turned ON. When the pressing of the stem 7 is released, the rotational pressing force applied to the rotating member 5 is released, and the movable contact 4 and the stem 7 return to their original states by the spring force of the movable contact 4 itself, and the switch is switched. Becomes OFF.

[0003]

However, in the above-mentioned conventional push-button switch, a turning member 5 is interposed between the movable contact 4 and the stem 7, and the turning member 5 is disposed above the turning member 5. Since the flat portion 11 of the stem 7 is located at the same position, the thickness of the rotating member 5 and the flat portion 11 of the stem is added as the height of the switch itself, and although a lateral push type push button switch structure is adopted, There is a problem that the thin function cannot be sufficiently performed. Therefore, the present invention has been made to solve the above-mentioned conventional technical problem, and has as its object to obtain a thin, laterally-push type push button switch.

[0005]

Therefore, in the push button switch of the present invention, the contact pressing portion is formed integrally with the operating member, and the bent portion of the holding plate is positioned in the notch provided in the operating member. Height dimension can be suppressed. Further, since the operating member is formed of one component, a push button switch can be obtained with a relatively simple configuration.

FIG. 1 is an exploded perspective view of a push button switch, FIG. 2 is a sectional view of a main part in a state where the push button switch is assembled, and FIG. 3 is a perspective view in a state where the push button switch is assembled.

In FIG. 1, reference numeral 11 denotes a housing. Fixed contacts 12 and 13 are formed on the housing 11 by insert molding. A plurality of terminals 14 and 15 extending from the fixed contacts are provided on a side wall of the housing 11. Are provided on the side wall of the case where the terminals 14 and 15 are not provided. A reversible movable contact 18 is mounted on the pair of fixed contacts 12. An operating portion contact portion 20 which functions as a stopper when the operating member 19 is pressed is provided on a side wall of the housing 11, and a guide wall 21 for contacting an end of the operating member is provided on the upper surface. And four guide projections 23 for holding the operation guide portion 22 of the operation member 19 on the upper surface of the housing 11.
However, a plurality of press plate guide protrusions 24 are provided. Reference numeral 25 denotes a dust-proof sheet made of a material such as polyamide, and the sheet 25 is configured so that its periphery is placed on the upper surface 26 of the housing 11. An operation member 19 is placed on the sheet 25, and the operation member 19 has an operation unit 27.
A contact pressing portion 29 having a thin portion 28 at the base and an operation guide portion 22 having a horizontally long protrusion 30 are provided, and a notch 31 is formed around the contact pressing portion 29.

Further, on the operating member 19 is attached the pressing plate 33 to prevent movement of the operating member 19 upward, the pressing plate 33 forms a pair of slits 34 on the upper surface, the slit portion A bent portion 35 bent downward in a U-shape is provided between the bent portions 35. Extending downwardly from one side wall of the pressing plate 33 is provided with a pair of mounting pieces 36 formed in substantially U-shaped recess 37 of the mounting piece 36 is located in the engaging portion 16, 17 of the housings 11 It is installed to do. A substantially I-shaped mounting piece 42 bent downward as shown in FIG. 4 is provided from a side surface of the holding plate 33 facing the mounting piece 36, and the mounting piece 42 is It is attached by fitting the pair of projections 38 provided on the side wall of the housings 11. A first projection 39 and a second projection 40 projecting downward are provided on the other side wall of the holding plate 33, and the first projection 39 is provided on the guide projection 23 of the housing 11. And the second protrusion 40 is configured to be located between the guide protrusions 23.
The guide recesses 4 provided at the four corners of the holding plate 33
1 has a configuration in which a projection 24 for guiding is located.

[0009] When assembling the push button switch having the above configuration, the movable contact 18 is placed on the fixed contact 12 of the housings 11, attaching the sheet 25 to cover the movable contact 18 on the upper surface 43 of the housing 11 Attach in the form to attach.
Then, the operation member 19 is positioned on the sheet 25, and the lower ends of the mounting pieces 36, 36 of the holding plate 33 are engaged with the engaging portions 16, 1.
7 and the lower end of the mounting piece 42 is positioned on an inclined surface 44 provided on the guide wall 21 of the housing 11, and the first and second projections 39 and 40 are arranged on the guide projection 23 and the guide. 11 located between the projections 23
By mounting on the upper side, the concave portion 37 of the mounting piece 36 can be mounted on the projections 16 and 17 and the lower portion of the mounting piece 42 can be mounted on the lower surface of the projection 38 with a small fitting force. Further, with the above structure, the holding plate 33 can be securely attached to the housing 11 without rattling. And projection 1

Further, the projection 30 becomes to slide smoothly on the housings 43 via the sheet 25, it becomes the movable contact 18 is in contact on the fixed contact 12 via the sheet 25, the switch is turned ON. When the pressing of the operating member 19 is released, the contact pressing portion 29 is pressed by the spring force of the movable contact 18, and the contact pressing portion 29 returns to the original state by slidably returning to the bent portion 35. . In the above-described embodiment, the protrusions 30 are formed horizontally long, and four protrusions 30 are formed on the upper and lower portions of the operation guide portion 23. However, this is an example, and the number of shapes may be other.

[0010]

As described above, in the push button switch of the present invention, the contact pressing portion is formed integrally with the operating member, and the bent portion of the holding plate is positioned in the cutout provided in the operating member. Therefore, a thin push button switch can be obtained. Further, since the operating member is constituted by one component, the number of components is reduced, and a low-cost push-button switch can be obtained.
