った。However, in the above-described conventional multi-directional input switch, a plurality of switch elements must be incorporated in the housing, so that the number of parts is large and downsizing is not easy. Further, since the operating rod is penetrated through a hemispherical elastic member disposed outside the housing, and the operating rod is returned to the neutral position in the tilting direction by the elastic member, there is a problem that downsizing is not easy. Further, a double pipe structure in which a shaft member is slidably arranged inside the operation rod is adopted, and by pressing this shaft member, a switch element arranged below the operation rod is pushed. For this reason, the structure becomes complicated, and from this point, there is a problem that downsizing is not easy.

The movable body 3 tilts with the end of the contact portion 33 as a fulcrum and the tilting direction of the cylindrical portion 31 (see FIG. 8 is in line contact with one of the lower fixed contacts 22. As a result, the integral fixed contact group 35 of the upper fixed contacts and one of the lower fixed contacts 22 are conducted through the conductive movable body 3, and a predetermined electric signal is output.

As a result, the movable body 3 in the contact state and the lower fixed contact 22 are separated from each other to be in a non-conductive state, and the movable body 3 pushes up the descending side of the hemispherical flange portion 7 to push the flange. Since the part 7 is returned to the neutral position shown in FIG. 1, the operating shaft 6 is also returned to the neutral position.

As shown in FIG. 7, the hemispherical flange 7 engaging with the projection 6a of the operation shaft 6 does not descend, and only the operation shaft 6 descends against the return spring 4. Then, since the pushing force of the operator is applied to the dome-shaped movable contact 23 via the rubber plate 24, when the center of the movable contact 23 is inverted and comes into contact with the center fixed contact 20, the movable contact 23 Common fixed contact 2

操作時に滑らかな操作感覚を得ることができる。As described above, the first embodiment employs the operating rod 1.
Can output an electric signal corresponding to the tilting direction or an electric signal corresponding to the push operation, and can automatically return to the initial state by releasing the operating rod 1 in the tilted state or the push state. The desired switching can be performed by tilting operation or push operation without incorporating a plurality of switch elements as in the conventional product, so that the number of parts of the multi-directional input switch can be greatly reduced and downsizing becomes easy. I have. In the above embodiment, insertion of the pressing portion 6b into the through hole 5a is allowed at the neutral position of the operating rod 1, but insertion of the pressing portion 6b of the operating shaft 6 is guided when the operating rod 1 is tilted. Since the operation rod 1 is blocked by the receiving surface 5b of the member 5, the push operation of the operation rod 1 is enabled only at the neutral position of the operation rod 1, and it is possible to prevent the push operation from being performed against the intention of the operator. Moreover, the operating shaft 6
The lower end of the pressing portion 6b is formed in a spherical shape around the swing center C of the operation shaft 6, and the receiving surface 5b of the guide member 5 is formed around the swing center C of the operation shaft 6. The lower end of the operating shaft 6 and the receiving surface 5 of the guide member 5
Since the contact with b is smooth, a smooth operation feeling can be obtained when the operating rod 1 is pushed.

保護できるという利点がある。Furthermore, since the movable body 3 is tilted with the outer peripheral portion opposite to the tilting direction as a fulcrum during the tilting operation, a large moment is generated in the movable body 3 even if the tilting operation force applied to the operating rod 1 is not so large. Therefore, the lower fixed contact 2
2 can easily secure the necessary contact pressure,
There is an advantage that operability and reliability during the tilting operation are improved. Since the outer periphery of the contact portion 33 of the movable body 3 is substantially octagonal, the outer periphery of the contact portion 33 is
In this state, the movable body 3 falls down in a line contact state, and the falling direction of the operating rod 1 can be regulated in a direction perpendicular to each side of the outer periphery of the contact portion 33. Furthermore, in the above-described embodiment, since the cushioning rubber plate 24 is interposed between the operation shaft 6 and the movable contact 23, the movable contact 23 can be protected. There is an advantage that the semi-spherical flange portion 7 can be protected because the rubber cushioning plate 34 is interposed between them.

An upper fixed contact 44 integrally formed on a lid 43 for closing the housing 41 and facing the lower fixed contact 42 is divided into two parts. The lower fixed contacts 42 are arranged at predetermined intervals along the circumferential direction of the operating rod 1, and the two upper fixed contacts 44 are arranged in the circumferential direction of the operating rod 1 while facing each other. The upper fixed contacts 44 are electrically connected to each other via a pattern (not shown) of the substrate 8. Further, a triangular hole 43a is provided in the upper part of the lid 43, and the upper fixed contact 44 is exposed through the hole 43a. This hole 43a is used for mounting the multidirectional input switch on the substrate 8. It functions as a guideline to recognize the direction.

簡単である。Also in the second embodiment, when the operating shaft 6 is tilted counterclockwise in FIG. 10 about the swing center C against the resilience of the return spring 4, the contact portion 33 tilts. The end located on the opposite side (left side in FIG. 10) is the upper fixed contact 4
4, the movable body 3 tilts around the end of the contact portion 33 as a fulcrum, and as shown by a two-dot chain line in FIG. A line contact is made with one of the lower fixed contacts 42. As a result, one of the upper fixed contact 44 and the lower fixed contact 42 via the conductive movable body 3
Are electrically connected, and a predetermined electric signal is output. Therefore, as in the first embodiment, desired switching can be performed by tilting operation without incorporating a plurality of switch elements. Furthermore, in the second embodiment, the need for the formed metal plate 11 is eliminated as in the first embodiment, so that the number of parts can be further reduced and the structure is simple.
