As shown in FIG. 3, the elastic portion 44 is configured in such a manner that when the movable contact portion 42 is separated from the fixed contact portion 22 by the force applied by the leaf spring portion 43, the pair of contact portions 443 and the case The inner surface 121 of the cover 12 of the body 10 that is opposite to the movable contact piece 40 is in contact with the inner surface 121 of the body 10 and elastically deforms in a direction in which the plate-like portion 441 approaches the body portion 41.

Furthermore, in the switch 1, the body portion 41, the movable contact portion 42, the plate spring portion 43, and the elastic portion 44 are integrally formed.

As shown in FIG. 2, the operation portion 50 has a substantially rectangular parallelepiped shape extending in the short-side direction of the base 11. As shown in FIG. 3, the operation portion 50 is such that the lower end portion 51 in the thickness direction of the base 11 and the body portion 41 of the movable contact piece 40 are in contact with each other between the first through hole 413 and the second through hole 414. The upper end portion 52 in the thickness direction of the base 11 is exposed from the operation hole 14 of the cover 12 to the outside of the casing 10. Moreover, the operation part 50 is arrange | positioned so that it can reciprocate in the thickness direction of the base 11.

Next, the operation of the switch 1 will be described with reference to FIGS. 3 to 8.

As shown in FIGS. 3 and 4, in the switch 1 in a restored state where no external force is applied to the operating portion 50, the movable contact portion 42 of the movable contact piece 40 is located at a restored position separated from the fixed contact portion 22, and the elastic portion 44 The pair of contact portions 443 and the inner surface 121 of the cover 12 facing the movable contact piece 40 are in contact with each other.

At this time, in the main body portion 41 of the movable contact piece 40, the end portion on the narrow side 412 side in the long-side direction of the base 11 is directed by the plate spring portion 43 in the thickness direction of the base 11 (that is, the Up and down direction) A force is applied in a first direction A1 (shown in FIG. 3) away from the first rectangular surface 111 of the base 11, and the movable contact portion 42 is urged toward the first direction A1. When viewed from the short side direction of the base 11, the middle portion 417 of the body portion 41 intersecting with a virtual straight line that passes through the second end portion 432 of the leaf spring portion 43 and extends in the thickness direction of the base 11 is located closer to the leaf spring portion. The second end portion 432 of 43 is positioned further upward (that is, in the thickness direction of the base 11 with respect to the second end portion 432 of the leaf spring portion 43 on the cover 12 side).

When an external force is applied to the upper end portion 52 of the operation portion 50 and the operation portion 50 is pressed in the second direction A2 (shown in FIG. 5) that is close to the base 11 in the thickness direction of the base 11, the body portion 41 of the movable contact piece 40 A region near the upper contact point 416 with the lower end portion 51 of the operation portion 50 is elastically deformed in the second direction A2, and the intermediate portion 417 is close to the second end portion 432 of the plate spring portion 43.

At this time, the force exerted by the leaf spring portion 43 on the body portion 41 becomes gradually smaller as the intermediate portion 417 approaches the second end portion 432 of the leaf spring portion 43, as shown in FIGS. 5 and 6. When viewed from the side (left-right direction in Figure 6), The position where the intermediate portion 417 overlaps the second end portion 432 of the leaf spring portion 43 (that is, the biasing direction switching position) becomes zero.

When the operation portion 50 is further pressed in the second direction A2, the area near the contact point 416 on the body portion 41 of the movable contact piece 40 and the lower end portion 51 of the operation portion 50 is further elasticized in the second direction A2. As shown in FIG. 7 and FIG. 8, the middle portion 417 is deformed to approach the base 11 beyond the second end portion 432 of the leaf spring portion 43.

At this time, while the middle portion 417 exceeds the second end portion 432 of the leaf spring portion 43 and approaches the base 11, the direction in which the leaf spring portion 43 applies the force to the body portion 41 (that is, the direction of the force applied to the movable contact portion 42). ) Is switched from the first direction A1 (that is, the separation direction) to the second direction A2 (that is, the contact direction). Thereby, the movable contact portion 42 is moved instantaneously in the second direction A2, and the contact body portion 423 of the first arm portion 421 is inclined toward the second direction A2 (that is, the direction in which the straight line L of FIG. 8 extends) to be fixed. When the curved surface 221 of the edge portion of the contact portion 22 contacts the operating position, the switch 1 becomes the operating state.

Thereafter, when the pressing of the operation portion 50 in the second direction A2 is released, the body portion 41 and the operation portion 50 of the elastically deformable movable contact piece 40 are restored from the operating positions shown in FIGS. 7 and 8 to FIG. 8. 3 and the recovery position shown in FIG. 4.

At this time, the restoring force of the main body portion 41 is located lower than the second end portion 432 of the leaf spring portion 43 (that is, in the thickness direction of the base 11 with respect to the second end portion of the leaf spring portion 43. 432 is the base 11 side), and the middle portion 417 moves in the first direction A1 and approaches the cover 12 beyond the second end portion 432 of the leaf spring portion 43. At the same time, the leaf spring portion 43 faces the body portion 41. Force direction (i.e. The direction of the force applied to the movable contact portion 42 is switched from the second direction A2 (that is, the contact direction) to the first direction A1 (that is, the separation direction). As a result, the movable contact portion 42 is momentarily moved in the first direction A1 and is moved to a recovery position separated from the fixed contact portion 22, so that the switch 1 is brought into a recovery state.

That is, since the movable contact portion 42 is in contact with or separated from the fixed contact portion 22, when the biasing direction switching position exceeds the position where the middle portion 417 of the main body portion 41 and the second end portion 432 of the leaf spring portion 43 coincide, the The urging direction of the leaf spring portion 43 to the movable contact portion 42 is switched from the separation direction to the contact direction, or from the contact direction to the separation direction.

When the movable contact portion 42 is separated from the fixed contact portion 22 and moved to the recovery position, as shown in FIGS. 3 and 4, a pair of contact portions 443 of the elastic portion 44 and the cover 12 of the housing 10 The movable contact piece 40 is in contact with the opposite inner surface 121 and elastically deforms in a direction in which the plate-like portion 441 approaches the body portion 41.
