In particular, as shown in FIG. 9, when two switch devices AR having the above-described structure are stored in a switch box standardized by the BS standard (hereinafter referred to as “BS box 140”) in a state where they are arranged in the front-rear direction. The switch device AR and the mounting portion 141 for mounting the BS box 140 to the mounted portion such as the wall portion interfere with each other. Therefore, in order to avoid the interference, an operation of bending the attachment portion 141 is necessary, and the operation is complicated.

  As a method for reducing the size of the switch device AR in the front-rear direction, it is conceivable to reduce the distance between the first terminal plate 110 and the second terminal plate 120 in the front-rear direction. However, since the plate thickness direction of the upper extension 112 coincides with the vertical direction, which is a direction orthogonal to both the front-rear direction and the left-right direction, the width of the upper extension 112 in the front-rear direction is increased. Therefore, in the conventional structure, the width in the front-rear direction of the body 100 is formed so as to ensure that the distance is not short-circuited between the first terminal plate 110 and the second terminal plate 120. Therefore, when the width of the body 100 in the front-rear direction is reduced in order to reduce the size of the switch device AR in the front-rear direction, the distance becomes smaller. As a result, a necessary insulation distance between the first terminal plate 110 and the second terminal plate 120 cannot be secured, and a short circuit may occur between the first terminal plate 110 and the second terminal plate 120. there were.

  Next, with reference to FIG. 7, an arrangement mode of the switch device A and a switch box standardized by the BS standard (hereinafter, “BS box 40”) will be described. The BS box 40 is attached to a wall portion (attachment body) such as a house by a screw member.

  As shown in FIG. 7A, the BS box 40 includes a peripheral wall 41 and a bottom wall 42 and is formed in a box shape having an open top. On the peripheral wall 41, four mounting portions 43 projecting toward the inside of the BS box 40 are provided at regular intervals.

According to the switch device A of the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the arm portion 20c of the first terminal board 20 is bent downward from the upper extension portion 20b and extends in the vertical direction. Therefore, since the plate thickness direction of the arm portion 20c coincides with the front-rear direction, the width in the front-rear direction of the arm portion 20c corresponding to the upper extension 112 of the conventional structure is reduced as compared with the conventional structure shown in FIG. Can do.

  In addition, the arm portion 20c is bent from the outer side edge in the front-rear direction of the upper extension portion 20b, so that the first terminal plate 20 and the second terminal plate 23 are compared with the conventional structure shown in FIG. The distance in the front-rear direction can be increased. Therefore, the distance can be secured even if the switch device A is downsized in the front-rear direction.

  Further, in the conventional structure shown in FIG. 8, it is considered to reduce the width in the front-rear direction of the upper extension 112 in order to secure the distance in the front-rear direction between the first terminal plate 110 and the second terminal plate 120. It is done. However, if the width is reduced, there is a problem that the electrical resistance in the upper extension 112 increases.

  In that respect, in the present embodiment, the plate thickness direction of the arm portion 20c coincides with the front-rear direction, so that the width can be secured by extending the arm portion 20c in the up-down direction. Therefore, since it does not extend in the front-rear direction in order to suppress an increase in the electrical resistance of the arm portion 20c, the above problem can be avoided.

  (2) In the present embodiment, since the attachment portion 43 is accommodated in the recess 10C and the recess 11a, it is possible to avoid interference between the attachment portion 43 and the switch device A. Therefore, the work of bending the BS box mounting portion, which is necessary in the conventional structure, can be omitted. As a result, the switch device A can be easily accommodated in the BS box 40.

  (3) In the present embodiment, the attachment portion 43 is arranged below the handle cover 33. Therefore, since the recessed part for avoiding interference with the attaching part 43 in the handle | steering-wheel cover 33 can be abbreviate | omitted, the fall of the aesthetics of the switch apparatus A can be suppressed.

  (4) In the present embodiment, the outer extension 20b is provided with the outer notch 20b1, and the arm 20c is provided at substantially the same position as the outermost portion in the front-rear direction of the upper extension 20b. Therefore, it is possible to efficiently achieve both the reduction in size of the first terminal board 20 in the front-rear direction and the securing of the distance from the second terminal board 23.

  (5) In the present embodiment, the first terminal plate 20 is configured by a metal plate having a plate thickness thinner than that of the first pillar terminal 21. Therefore, the first terminal plate 20 can be easily formed by press working as compared with the first pillar terminal 21, and therefore the first terminal plate 20 can be easily formed into a complicated shape.

According to this structure, the role which hold | maintains the 2nd terminal board 23 in the body 10 and the role which ensures the bounce performance with respect to the contact of the switching element 32 can be divided. In particular, in order to ensure bounce performance, the contact portion 23d is provided by bending downward from the upper extension portion 23b, so that the contact portion 23d is outward in the left-right direction against the force caused by the contact between the switching element 32 and the contact portion 23d. It becomes easy to elastically deform. Accordingly, both the second terminal plate 23 can be satisfactorily held with respect to the body 10 and the bounce performance of the contact portion 23d can be ensured.

  On the other hand, in such a second terminal plate 23, the width in the front-rear direction is larger than that of the second terminal plate 120 having the conventional structure shown in FIG. In that respect, by using the first terminal plate 20 of the present embodiment, an increase in the size of the width H1 in the front-rear direction formed by connecting the first terminal plate 20 and the second terminal plate 23 in the front-rear direction is suppressed. be able to.

  (15) In this embodiment, the width H1 in the front-rear direction formed by connecting the first terminal plate 20 and the second terminal plate 23 in the front-rear direction is such that the first pillar terminal 21 and the second pillar terminal 24 are in the front-rear direction. It is smaller than the width H2 in the front-rear direction formed by tying. Therefore, it is possible to achieve both ensuring the distance between the first pillar terminal 21 and the second pillar terminal 24 and reducing the size of the switch device A in the front-rear direction by the recess 10C.
