An operation body 6 mounted on the driving body 5 is a resin operation body, and a flat plate-like tip along a center line connecting the center of the concave portion of the case 1 and the window 1A projects from the window 1A. In addition to forming the portion 6A, a central hole 6B is provided at a position corresponding to the central portion of the concave portion of the case 1. The central hole 6B is an oval elongated in the direction of the center line, as shown in FIG. As described above, it is slidably engaged with the circular projection 5G at the center of the upper surface of the driving body 5 in the longitudinal direction.

Next, the operation of the multidirectional operation switch configured as described above will be described.

In the neutral state shown in FIG.
As shown by an arrow in the plan view of the state where the cover is removed during the swinging operation of (a), a rightward pressing force is applied to the operating portion 6A of the operating body 6 protruding from the window 1A of the case 1. The operating body 6 swings around the circular projection 5G of the driving body 5 as a fulcrum, and as shown by an arrow in FIG. 6B, which is a cross-sectional view taken along line QQ in FIG. Since the first contact portion 6D on the lower surface of the portion 6C moves while pushing the first inclined portion 5D of the driving body 5 to the left in FIG. 6B, the driving body 5 has the corner 5H on the upper surface side as a fulcrum. As a result, the first pressing portion 5A on the lower surface of the first inclined portion 5D pushes the dome-shaped portion 4B of the movable contact 4 downward to perform a partial reversing operation with a sense of moderation and contact the lower first fixed contact 2A. .

As a result, the common fixed contact 2 and the first fixed contact 2A are electrically connected via the movable contact 4, and the signal is derived from the switch terminal 3 which is electrically connected to each contact.

When the pressing force applied to the operation section 6A is removed, the movable contact 4 which has been partially inverted returns to the original circular dome shape by the elastic restoring force, and the driving body 5 is pushed back upward, and the driving body 5 is pushed back. The first inclined part 5D of the operation body 6
By pressing the first contact portion 6D rightward in FIG. 6B, the operating body 6 returns to the original neutral position of FIG. 1 and returns to the normal state.

Similarly, when a leftward pressing force is applied to the operation unit 6A, the common fixed contact 2 and the second fixed contact 2B are electrically connected.

In the neutral state of FIG. 1, FIG.
As shown by an arrow in the plan view of the state where the cover is removed at the time of the pressing operation of (a), when a pressing force toward the center of the case 1 is applied to the operating portion 6A protruding from the case 1, the operating body 6 As shown by arrows in FIG. 7B, which is a cross-sectional view taken along the line RR in FIG. 7A, it is pushed in along the longitudinal direction of the oval central hole 6B engaged with the protrusion 5G of the driving body 5. Then, the third contact portion 6F at the tip of the flat plate portion 6C moves while pushing the third inclined portion 5F of the driving body 5 rightward in FIG. 5I, the third pressing portion 5C on the lower surface of the third inclined portion 5F partially pushes the dome-shaped portion 4B of the movable contact 4 downward to perform a partial reversing operation with a sense of moderation and to fix the third lower portion. Contact the contact 2C.

As a result, conduction between the common fixed contact 2 and the third fixed contact 2C is conducted via the movable contact 4, and the signal is derived from the switch terminal 3 which is conducted to each contact.

When the pressing force applied to the operating portion 6A is removed, the driving body 5 and the operating body 6 return to the original neutral position shown in FIG. 1 by the elastic restoring force of the movable contact 4.

As described above, according to this embodiment, tangling and deformation are less likely to occur during the handling of the constituent members, the assembling work is simple, the automatic assembling is easy, and the multi-directional operating with a sense of moderation. An operation switch can be obtained.

In the above configuration, the third inclined portion 5F of the driving body 5 with which the third contacting portion 6F of the operating body 6 is in contact.
Is set to be steeper than the gradient of the first inclined portion 5D and the second inclined portion 5E of the driving body 5 with which the first contact portion 6D and the second contact portion 6E of the operating body 6 are in contact. Thereby, the operating force at the time of pressing the operation unit 6A to conduct the connection between the common fixed contact 2 and the third fixed contact 2C is changed to the common fixed by swinging the operation unit 6A rightward or leftward. The operating force at the time of making the contact 2 conductive with the first fixed contact 2A or the second fixed contact 2B can be made larger, and the common fixed contact 2 and the third fixed contact 2C become conductive at the time of the swing operation of the operation unit 6A. It is possible to make it less likely that a malfunction will occur.

The inclination of the first inclined portion 5D and the inclination of the second inclined portion 5E of the driving body 5 are not necessarily required to be the same, and the operating portion 6A is swung right and left by changing the inclination of both. It is also possible to make a difference in the operation force when performing the dynamic operation.

As shown in FIG. 6 (a), the projection 6G provided on the lower surface of the root of the operating portion 6A of the operating body 6 swings by applying a rightward or leftward pressing force to the operating portion 6A. When operating, it moves along the outer periphery of the peripheral wall of the case 1. As shown in FIG. 7A, when a pressing force is applied to the operation unit 6A in the center direction of the case 1, the pressing operation of the case 1 is performed. It is set so as to enter into the notch 1C at the center of the window 1A,
This is for preventing malfunction of the multi-directional operation switch.

As described above, according to the present embodiment, each inclined portion 5D-5F of the driving body 5 and each contact portion 6D-
Since the configuration is such that the circular dome-shaped movable contact 4 is partially inverted through the 6F, tangling and deformation are less likely to occur at the time of handling of the constituent members, and the assembling work is simple and easy even in automatic assembling. A multi-directional operation switch that operates in a short time can be realized.
