When the predetermined position is exceeded, the direction of the urging force is reversed, and the sliding body 40 is urged in a direction to approach the center line CL1.

The leaf spring 60, the leaf spring support portion 46 of the sliding body 40, and the leaf spring support portion 54 of the operating body 50 constitute a snap action mechanism portion.

That is, the first switch mechanism unit 31 and the second switch mechanism unit 32 are each composed of a set of a sliding body 40, an operating body 50, a snap action mechanism unit, and a contact mechanism unit.

Next, the operation of the switch 1 configured as described above will be described with reference to FIGS. The first switch mechanism 31 and the second switch mechanism 32 operate in the same manner except for the moving direction of the sliding body 40 and the operating body 50. Therefore, the operation of the first switch mechanism unit 31 will be described, and the operation of the second switch mechanism unit 32 will be omitted.

The position of the sliding body 40 in a state where no force is applied to the operation protrusion 56 of the operation body 50 (that is, the state where the operation protrusion 56 is at the position indicated by the solid line in FIG. 1) is defined as the first return position. The position 50 is set as the second return position. The first return position and the first operation position are located on a center line CL <b> 2 that is a first straight line extending along the first sliding plane 15.

Further, the position of the sliding body 40 in the state where the operating body 50 is moved to the limit by applying a force to the operating protrusion 56 of the operating body 50 (that is, the state where the operating protrusion 56 is at the position indicated by the dotted line in FIG. 1). The first operation position is set, and the position of the operating body 50 is set as the second operation position. The second return position and the second operation position are located on a center line CL3 (shown in FIG. 4) which is a second straight line extending along the second sliding plane 45 and parallel to the first straight line.

As shown in FIG. 6, when viewed from the direction intersecting the first sliding plane 15 of the housing 10, the sliding body 40 at the first return position and the operating body 50 at the second return position are partially part of each other. Are arranged in a state of overlapping.

First, when the operating projection 56 of the operating body 50 at the second return position shown in FIG. 6 is pressed in the first direction A1 (shown in FIG. 7) away from the center line CL1 in the longitudinal direction of the base 11, the operating body 50 returns. It moves in the first direction A1 against the elastic force of the spring 59. At this time, each leaf spring 60 biases the sliding body 40 in the first direction A1.

Then, the operation protrusion 56 of the operation body 50 is further pressed in the first direction A1, and the second flat plate portion 62 connected to the leaf spring support portion 54 of the operation body 50 of each leaf spring 60 is pressed as shown in FIG. When the base part exceeds a straight line L (an example of a predetermined position) connecting the base parts of the first flat plate part 61 connected to the leaf spring support part 46 of the sliding body 40, simultaneously, the energizing direction of each leaf spring 60 Is reversed from the first direction A1 to the second direction A2 (shown in FIG. 9) approaching the center line CL1 in the longitudinal direction of the base 11.

At this time, due to the reversal of the urging direction of each leaf spring 60, the sliding body 40 is second from the first return position shown in FIG. 7 in the opposite direction to the movement direction of the operating body 50 (ie, the first direction A1). It moves instantaneously in the direction A2 to the first operating position shown in FIG. Thus, the conduction state between the first movable contact portion 81 and the first fixed contact portion 71 and the second fixed contact portion 72, the second movable contact portion 82, the third fixed contact portion 73, and the fourth fixed contact portion. The conduction state between the switch 74 and the switch 74 is switched at substantially the same time.

In the state where the sliding body 40 is located at the first return position (shown in FIG. 6), the curved plate portion 63 of the leaf spring 60 is located in the vicinity of the leaf spring support portion 54 of the operating body 50. . Thereafter, when the operating body 50 is moved in the first direction A1, the curved plate portion 63 of the leaf spring 60 gradually approaches the leaf spring support portion 46 of the sliding body 40 in conjunction with the movement of the operating body 50. To go. That is, in a state where the base of the second flat plate portion 62 is positioned on a straight line L connecting the base portions of the first flat plate portion 61 (shown in FIG. 7), the curved plate portion 63 is a leaf spring of the sliding body 40. In the state (shown in FIG. 8) where the sliding body 40 is located at the first operation position, which is located at the approximate center between the support portion 46 and the leaf spring support portion 54 of the operating body 50, the plate of the sliding body 40 is used. It is located in the vicinity of the spring support 46.

After that, when the pressing of the operating body 50 against the operating projection 56 in the first direction A1 is released, the operating body 50 moves in the second direction A2 from the second operating position shown in FIG. . At this time, each leaf spring 60 biases the sliding body 40 in the second direction A2.

Then, the operating body 50 is further moved in the second direction A2 by the elastic force of the return spring 59, and the base portions of the second flat plate portions 62 of the plate springs 60 are connected to the base portions of the first flat plate portions 61 as shown in FIG. When a straight line L (an example of a predetermined position) is crossed, the urging direction of each leaf spring 60 is reversed from the second direction A2 to the first direction A1.

At this time, due to the reversal of the urging direction of each leaf spring 60, the sliding body 40 is moved from the first operation position shown in FIG. It moves instantaneously in the direction A1 to the first return position shown in FIG. Thus, the conduction state between the first movable contact portion 81 and the first fixed contact portion 71 and the second fixed contact portion 72, the second movable contact portion 82, the third fixed contact portion 73, and the fourth fixed contact portion. The conduction state between the switch 74 and the switch 74 is switched substantially simultaneously.

In the state where the sliding body 40 is located at the first operating position (shown in FIG. 8), the curved plate portion 63 of the leaf spring 60 is located in the vicinity of the leaf spring support portion 46 of the sliding body 40. . Thereafter, when the operating body 50 is moved in the second direction A2, the curved plate portion 63 of the leaf spring 60 gradually approaches the leaf spring support portion 54 of the operating body 50 in conjunction with the movement of the operating body 50. To go. That is, in a state where the base of the second flat plate portion 62 is located on a straight line L connecting the base portions of the first flat plate portion 61 (shown in FIG. 9), the curved plate portion 63 is a leaf spring of the sliding body 40. In a state (shown in FIG. 10) in which the sliding body 40 is located at the first operating position, which is located at the approximate center between the support portion 46 and the leaf spring support portion 54 of the operation body 50. It is located in the vicinity of the spring support portion 54.

In the switch 1, the first sliding plane 15 is arranged so as to be linearly reciprocable on the first sliding plane 15 of the housing portion 14 of the housing 10 and in a direction intersecting the first sliding plane 15. And a plate-like sliding body 40 having a second sliding plane 45 arranged at an interval with respect to the second sliding plane 45 and accommodated in the accommodating portion 14 so as to be linearly reciprocable on the second sliding plane 45. A plate-like operation body 50 is provided. That is, the sliding body 40 is arranged to be linearly reciprocable on the first sliding plane 15, and the operating body 50 is arranged to be linearly reciprocable on the second sliding plane 45. Since the first sliding plane 15 and the second sliding plane 45 overlap each other in the direction crossing 15, the size of the sliding body 40 and the operating body 50 in the moving direction can be reduced.

Further, the moving direction from the first return position of the sliding body 40 to the first operating position and the moving direction of the operating body 50 from the second return position to the second operating position are opposite to each other. The moving range of the sliding body 40 and the moving range of the operating body 50 overlap each other. For this reason, size reduction can be achieved in the moving direction of the sliding body 40 and the operating body 50.

The moving distance D (shown in FIG. 8) of the sliding body 40 between the first return position and the first operating position is equal to the limit moving distance of the sliding body 40 necessary for switching the conduction state of the contact mechanism section. Thus, by configuring the switch 1, further downsizing can be achieved in the moving direction of the sliding body 40 and the operating body 50.

In the switch 1, when viewed from the direction intersecting the first sliding plane 15, the operating body 50 of the first switch mechanism portion 31 and the operating body 50 of the second switch mechanism portion 32 are adjacent to each other, and The return spring 59 is provided between the operating body 50 of the first switch mechanism section 31 and the operating body 50 of the second switch mechanism section 32 while being arranged symmetrically with respect to the center point 16 of the housing section 14. ing. Thereby, when two switch mechanism parts are provided, the return spring 59 which urges the operating body 50 to the second return position can be shared, and the number of parts can be reduced. As a result, the size can be further reduced.

Note that the number of switch mechanism units is not limited to two, that is, the first switch mechanism unit 31 and the second switch mechanism unit 32, and only one or three or more switch mechanism units may be provided.

Further, the switch 1 is arranged so as to be linearly reciprocable on at least the sliding body 40 on the first sliding plane 15, and the operating body 50 is arranged to be linearly reciprocable on the second sliding plane 45. The first sliding plane 15 and the second sliding plane 45 only need to overlap in the direction intersecting the first sliding plane 15. That is, the moving range of the sliding body 40 and the moving range of the operating body 50 do not have to overlap.
