DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on embodiments shown in the drawings. FIG. 1 is an external view of a multi-directional switch according to a first embodiment of the present invention. Reference numeral 1 denotes a switch case, and 2a denotes a switch operation unit operated from outside the switch case 1.

The operator performs switching by vertically pressing the switch operating section 2a or tilting the switch operating section 2a in the direction in which the operator wants to operate. FIG. 2 is a partial perspective view of the switch conductive portion and the switch pattern, and FIG. 3 is a cross-sectional view taken along line AA 'of FIG. 4 is a cross-sectional view in which the switch operation unit 2a in FIG. 3 is pushed in the vertical direction, and FIG. 5 is a cross-sectional view in which the switch operation unit 2a in FIG.

Referring to FIGS. 2, 3, 4 and 5, a first embodiment of the present invention will be described in detail. Switch operation unit 2a
Is a member formed of plastic, and a switch movable portion 2b made of rubber is integrally formed below the member. The switch movable section 2b has a dome shape, and includes a peripheral dome section 2d and a peripheral switch pressing section 2e. The switch pressing part 2e is provided with a conductive member 2c formed by printing conductive rubber and a conductive member 2g formed by printing conductive rubber also at the center thereof. In addition, a protrusion 2f is provided on the outer periphery of the conductive member 2g.

On the substrate 3, switch patterns 3a to 3e are formed at positions corresponding to a plurality of switch operation directions. The switch case 1 includes a switch movable section 2b
Is provided with a recessed portion 1a for accommodating the dome portion 2d provided in the above. The dome portion 2d is stored in the hollow portion 1a,
Further, by fixing the substrate 3 under the dome portion 2d to the switch case 1, it can be assembled as a switch.

In the assembled state, the circumferential convex portion 2f provided on the switch pressing portion 2e contacts the substrate 3, and the switch operating portion 2a operates with the convex portion 2f as a fulcrum. Next, the operation of the multidirectional switch configured as described above will be described. As shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, for example, when the switch operation unit 2a is moved so as to be pushed in the vertical direction, the dome portion 2d of the switch movable portion 2c is deformed, and further, the circumferential convex portion 2f The entire surface is pressed, and the conductive member 2g of the switch pressing portion 2e contacts the switch pattern 3e to conduct.

On the other hand, since the conductive member 2c provided on the outer peripheral portion is formed at a position farther from the switch pattern surface than the conductive member 2g, it does not come into contact with the switch patterns 3a to 3d, so that the vertical switch is turned on. It will be done.
Further, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 5, for example, when the switch operation part 2a is moved so as to be tilted in the direction A, the dome part 2d of the switch movable part 2b is bent, and the vicinity of the switch pattern 3b Is deformed, the conductive member 2c of the switch pressing portion 2e comes into contact with the switch pattern 3b in the A direction and becomes conductive.

On the other hand, since the conductive member 2g provided at the center can be lifted up with the linear portion of the circumferential convex portion 2f as a fulcrum, the switch in the direction A is turned on by not contacting the switch pattern 3e. . As described above, by vertically pressing the switch operating unit or tilting the switch operating unit in multiple directions, the switch pattern in the operating direction and the conductive member of the switch come into contact with each other to conduct, so that switching can be performed in multiple directions. .

[0014]

As described above, according to the present invention,
In a multi-directional switch structure of an electronic device, a switch pattern in multiple directions is configured to be switched by one conductive unit and an operation unit. For this reason, a small vertical and multidirectional switch can be realized.

Further, when the switch operating portion is pressed vertically, the entire surface of the circumferential convex portion becomes a fulcrum, and when the switch operating portion is tilted in multiple directions, a straight portion in the direction in which the circumferential convex portion is tilted is formed. A stable switch operation can be performed by the switch structure serving as a fulcrum.
