Definitions
- the present invention relates to a seesaw key-compatible switch using an out-contour rubber switch for operating home appliances, mobile phones, automobile parts, and the like.
- Some switches mounted on home appliances and vehicles use contact rubber switches.
- Such a switch is mainly composed of a key top and an operation knob that are pressed, and a rubber switch that is pressed down by these keys.
- the key top is pressed with a finger, the rubber switch is pushed down, and contact is made with the fixed contact formed on the movable contact force substrate formed on the lower surface of the switch, and conduction is obtained.
- the sea contact switch which has a tapered contact surface with an angle parallel to the fixed contact when the movable contact is pushed down, and the contact portion that contacts the operation knob protrude upward.
- a sea sauce switch or the like having a small contact area with the operation knob (see, for example, Patent Documents 1 and 2).
- a switch that presses the pusher with the operation knob and presses the movable contact of the rubber contact switch with this pusher It has been proposed (see Patent Document 3).
- these switches have problems that a sufficiently good click feeling cannot be obtained, and that the number of parts increases and the structure becomes complicated.

- the push button portion of the contact rubber switch includes a central portion having a high slope on the rotating fulcrum side, an outer peripheral portion surrounding a portion other than the rotating fulcrum side of the central portion, and the central portion And a thin slit separating the outer peripheral portion, and when the operating portion of the operation knob comes into contact with the push button portion of the contact rubber switch, it contacts only the upper surface of the central portion of the push button portion. But don't touch the outer circumference, even if it is!
- the contact rubber switch is configured such that, at the preload stage of the key top, the movable contact is inclined downward toward the rotation fulcrum, and the inclination angle of the movable contact gradually increases during the pressing operation. Finally, the movable contact can come into contact with the fixed contact almost in parallel.
- the thick skirt portion on the counter-rotating fulcrum side of the operation knob is deformed all at once, giving the user a click feeling indicating that the pressing operation is completed. It is preferable.
- the movable contact of the push button portion can be brought into surface contact in a substantially parallel posture with the fixed contact on the substrate.
- the force of the contact force has only been devised, and the number of parts has not increased. Therefore, it is possible to provide a switch having a simple structure while operating stably.

- the skirt portion 13a on the anti-fulcrum side is thick as described above, and is provided so that the bottom surface force of the sub-portion 12b of the push button portion 12 protrudes obliquely downward. The part 13a does not bulge outwards much.
- the skirt portion 13b on the fulcrum side which is easily deformed swells outward and further deforms. As a result, the push button portion 12 is pushed downward while moving inward (rotation fulcrum P side). Then, there is almost no inclination angle of the movable contact 14 with respect to the horizontal plane, and it becomes almost parallel to the fixed contact 3 so that both contacts 3 and 14 come into contact with each other.
