Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push button switch having a plurality of push buttons, and is suitable for opening and closing a sunroof of an automobile, for example.

2. Description of the Related Art Conventionally, a switch having a plurality of push buttons generally requires as many movable switch elements as there are push buttons (for example, Japanese Utility Model Laid-Open No. 62-28330).

Problems to be Solved by the Invention Needless to say, with such a configuration, the number of movable switch elements increases, and the storage space for that increases, which is disadvantageous in terms of cost.

Therefore, it is an object of the present invention to provide a low-cost pushbutton switch that can reduce the number of movable switch elements and simplify the structure.

Means for Solving the Problems According to the present invention, a body, a plurality of pushbuttons that are arranged side by side in the body in a protruding direction by a spring, and a plurality of pushbuttons are arranged between inner ends of adjacent pushbuttons. Then, by pressing one of the push buttons, the slide body is slid in a direction perpendicular to this pressing direction, and by releasing the press of the push button, the slide body is returned to a fixed position extending between the inner ends of the adjacent push buttons. The return spring includes a return spring, a movable contact piece fixed to the slide body, and a fixed contact piece with which the movable contact piece comes in contact with and separates from each other. The push-button switch is characterized in that it has a substantially V-shape and is located in a notch formed substantially in the center.

According to a second aspect of the present invention, three or more push buttons are provided, and the slide body includes a slide body that is directly slid by pressing one of the push buttons and another slide body that is slid by the sliding of the slide body. The push button switch according to claim 1 is provided.

According to a third aspect of the present invention, a body, a plurality of pushbuttons that are juxtaposed to the body in the protruding direction by a spring, and a plurality of pushbuttons are arranged between inner ends of adjacent pushbuttons. A slide body that is slid in a direction perpendicular to this pressing direction by pressing, a return spring that returns the slide body to a fixed position across the inner ends of adjacent push buttons by releasing the pressing of the push button, and the slide body A movable contact piece fixed to the movable contact piece and a fixed contact piece to which the movable contact piece contacts and separates, three or more push buttons are provided, and the slide body is directly slid by pressing one of the push buttons. And a slide body which is slid by the slide of the slide body.

Operation According to the present invention, the slide body provided with the movable contact piece is located across the inner end portions of the adjacent push buttons, and is slid in the direction perpendicular to the pressing direction by pressing one of the push buttons. Therefore, the number of movable switch elements, that is, the number of slide bodies provided with movable contact pieces can be made smaller than the number of push buttons. Further, in the present invention, by releasing the pressing of the push button, the return spring returns the slide body to the fixed position extending between the inner end portions of the adjacent push buttons, so that the next push of the push button can be hindered. Further, even if a plurality of push buttons are pushed in at the same time, forces in opposite directions are applied to the slide body, and simultaneous push is prevented.

In addition, the return spring is positioned between the adjacent pushbuttons in a substantially V-shape.
By constructing the character-shaped member, the storage space for the return spring can be secured without increasing the size of the body.

Furthermore, if the number of pushbuttons is 3 or more,
By configuring a slide body that is directly slid by pressing the push button to slide another adjacent slide body, complicated switch switching can be dealt with.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. Three push-buttons 3 are provided in the insertion holes 1a, which are formed of an insulating material, and are arranged in parallel at three positions on the operation surface side of the body 1. To be The slide body 4 formed of an insulating material has a length that is located between the inner ends 3a of the adjacent push buttons 3, and when any one of the push buttons 3 is pressed, a direction perpendicular to the pressing direction is obtained. To be slid on.

In order for the slide body 4 to slide smoothly, at a fixed position where the slide body 4 extends between the inner end portions 3a of the adjacent push buttons 3 (see FIG. 5A), the tip corners of the inner end portion 3a are on both sides of the slide body 4. It suffices if the positions are mutually set so as to face each other on the inclined surface 4a. As another means, a slide body 4 having a substantially rectangular shape without the inclined surface 4a is used.
An inclined surface may be provided at the tip corner portion of the inner end portion 3a, and the inclined surface and the corner portion of the slide body 4 may be opposed to each other. As still another means, the inclined surface 4a may be provided on both sides of the slide body 4. It is also possible to provide an inclined surface at the tip corner of the inner end portion 3a, and to make the inclined surface and the inclined surface 4a of the slide body 4 face each other. It is only necessary to be able to slide.

When the push button 3 returns to its original position by the spring 2 when the push button 3 is released, the return spring 5 also restores the slide body 4 to a fixed position across the inner ends 3a of the adjacent push buttons 3. The return spring 5 is, for example, an adjacent push button 3
It is a substantially V-shaped member which is provided by effectively utilizing the dead space between the two, and has its center fixed and both ends located in notches 4b formed at substantially the center of the slide body 4, respectively. More specifically, the central winding portion of the return spring 5 is housed around the boss 1b protruding in the body 1,
It can be properly fixed by crushing the tip of the boss 1b. The movable contact piece 6 is fixed to the slide body 4, and as the fixing means, for example, the hole 6a of the movable contact piece 6 is positioned on the protrusion 4c of the slide body 4 and the locking holes on both sides of the movable contact piece 6 are provided. 6b is locked to the locking projections 4d on both sides of the slide body 4. The fixed contact piece 7a with which the movable contact piece 6 contacts and separates is formed, for example, as a copper foil of the printed circuit board 7 attached to the side surface opening of the body 1.

To describe another configuration of this embodiment, mounting pieces 1c for mounting the switch on the mounting surface are formed on both sides of the body 1. A hole 9 urged by a coil spring 8 housed in a recess 1d in the body 1 is brought into contact with the back surface of the slide body 4 to allow the slide body 4 to move more smoothly. The base end of the terminal 10 is inserted into the end portion of the printed circuit board 7 and soldered to maintain a predetermined electrical connection with the fixed contact piece 7a. The tip of the terminal 10 is inserted into a through hole (not shown) of the partition plate 1e formed on the one end side of the body 1, and the hole 7c of the printed board 7 is inserted.
