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 convex portion 2f provided on the switch pressing portion 2e comes into contact with the substrate 3, and the switch operating portion 2a
Are inclined 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 FIGS. 1, 2 and 3, for example, when the switch operating portion 2a is moved so as to be tilted in the direction A, the dome portion 2d of the switch movable portion 2c bends with the convex portion 2f as a fulcrum, and the switch pressing portion 2e. When the conductive member 2c contacts the switch pattern 3b in the A direction and conducts, the switch in the A direction is turned on. As described above, when the switch operation unit is tilted in multiple directions, the switch pattern in the operation 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.

In the first embodiment, the convex portion 2f is provided at the center of the switch pressing portion 2e of the switch movable portion 2b. However, the convex portion is provided at a position corresponding to the center of the switch pressing portion 2e of the substrate 3. Also, a multidirectional switch according to the present invention can be configured. FIG. 4 is a cross-sectional view of a multi-directional switch according to the second embodiment configured as described above. As shown in FIG.
Is provided on the substrate 3. Even with this configuration,
If you push the switch operation part in the circumferential direction, the switch operation part will
Since the projection 3e tilts with the projection 3e as a fulcrum, it has the same function as that of the first embodiment.

Next, a third embodiment of the present invention will be described in detail with reference to FIGS. FIG. 5 is a partial perspective view of the packing storage portion of the switch case 1 and the outer diameter of the switch movable portion and the convex packing portion, and FIG. 6 is a sectional view of FIG. In this embodiment, the switch case 1 shown in FIG. 3 is provided with a packing housing portion 1b and a convex packing portion 2g on the outer periphery of the switch movable portion 2b.

A third embodiment of the present invention will be described in detail.
The switch case 1 has a back cover 4 and a back cover packing 5 for maintaining waterproofness, and the components of the switch are configured in the same manner as in the first embodiment. The dome portion 2d of the rubber switch movable portion 2b is provided with a newly convex packing portion 2g.
The recessed portion 1a is further provided with a concave packing storage portion 1b.

When the dome portion 2d is housed in the hollow portion 1a and the packing portion 2g is housed in the packing housing portion 1b and the substrate 3 is fixed to the switch case 1, the packing portion 2g is pressed and compressed by the packing housing portion 1b. As a result, the waterproof structure of the multi-directional switch is realized by preventing water from entering the inside of the device.

[0015]

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 multidirectional switch can be realized. Further, a convex packing part is provided around the switch movable part, and a packing storage part for storing the same in the switch case. For this reason, a multidirectional switch having waterproofness was realized.
