  As shown in FIGS. 2 and 3, the movable body 20 of the movable body 2 has a quadrangular shape in cross section, and is adjacent to the first side 24 and the first side 24 that are opposed to each other. It has the 2nd side part 25 of the straight shape which mutually opposes. Here, the first side 24 of the movable body 20 faces the first inner wall surface 12 a of the base 1. In addition, one second side 25 of the movable body 20 faces one second inner wall surface 12c of the base 1 via a gap 71f. The other second side portion 25 faces the other second inner wall surface 12c of the base portion 1 via a gap 71s. Friction between the movable body 20 and the second inner wall surface 12c of the base 1 can be reduced by the gaps 71f and 71s.

And the attitude | position of the 2nd movable contact piece 22c is stabilized also in the direction orthogonal to a sliding direction also in the sliding direction (arrow P1, P2 direction) of the movable body 2. As shown in FIG. Therefore, the sliding locus of the movable body 2 is stabilized, and the posture and the sliding locus of the first movable contact piece 22a and the second movable contact piece 22c are stabilized. Therefore, even when the sliding switch is used for a long period of time, the contact failure between the first fixed contact piece 16a and the first movable contact piece 22a, and the contact between the second fixed contact piece 16c and the second movable contact piece 22c. This is advantageous for suppressing poor contact. As a result, it is advantageous to suppress poor contact between the fixed contact piece 16 and the movable contact piece 22.

  As shown in FIG. 3, in the switch-off position, a gap 7a having a minute gap width K1 is formed between the first movable contact piece 22a of the movable body 20 and the first inner wall surface 12a of the base 1. ing. Similarly, a gap 7c having a minute gap width K2 is formed between the second movable contact piece 22c of the movable body 20 and the first inner wall surface 12a of the base 1 at the switch-off position. Note that K1 and K2 are substantially equivalent values (K1 = K2, K1≈K2). Since the gaps 7a and 7c are formed in this way, even when the movable body 2 slides, the movable contact piece 22 is suppressed from rubbing the inner wall surface 12 of the base 1 and the generation of wear powder is suppressed. Is done.

  As shown in FIG. 5 (switch-on position), the first fixed contact piece 16a and the second fixed contact piece 16c have a protrusion 17 protruding toward the movable body 2 side. Thereby, the sliding resistance between the first fixed contact piece 16a and the first movable contact piece 22a and the sliding resistance between the second fixed contact piece 16c and the second movable contact piece 22c are further reduced. This is more advantageous for stabilizing the posture of the movable body 2. The protrusion 17 is located at the center of the first movable contact piece 22a and the second fixed contact piece 16c.

  As shown in FIG. 5, a lateral gap 80 is formed between the end surface 22 h of the first movable contact piece 22 a and the second inner wall surface 12 c of the base 1. Further, a lateral gap 80 is formed between the end face 22 h of the second movable contact piece 22 c and the second inner wall surface 12 c of the base 1. As a result, even if the first movable contact piece 22a and the second movable contact piece 22c move, rubbing of the end face 22h is avoided and generation of wear powder is further suppressed.

  As can be understood from FIG. 1, the center line between the first movable contact piece 22 a and the second movable contact piece 22 c is arranged coaxially with the operation portion 21 of the movable body 2. The first movable contact piece 22a and the second movable contact piece 22c are symmetrical with each other via the center line PA. That is, the first movable contact piece 22a and the second movable contact piece 22c are symmetric with respect to a plane (virtual plane) including the center line PA. For this reason, it becomes more advantageous to stabilize the sliding posture of the movable body 2 and further advantageous to stabilize the sliding locus of the movable body 2. In this case, it is further advantageous to suppress poor contact between the first fixed contact piece 16a and the first movable contact piece 22a, and poor contact between the second fixed contact piece 16c and the second movable contact piece 22c.

  As shown in FIG. 1, since the contact formed by the top portions 27 of the first movable contact piece 22a and the second movable contact piece 22c is formed by an arc convex surface, the conductive contact area can be reduced, and the low friction resistance can be achieved. Has sex and good sliding surname. For this reason, the sliding locus of the movable body 2 is further stabilized, poor contact between the first fixed contact piece 16a and the first movable contact piece 22a, and poor contact between the second fixed contact piece 16c and the second movable contact piece 22c. It is further advantageous to suppress the above.

  In a normal state, as shown in FIG. 1, the movable body 2 is separated in a direction away from the fixed contact piece 16 (in the direction of arrow P <b> 1) by the spring force of the urging member 3 and is maintained at the switch-off position. . In this switch-off position, as shown in FIG. 1, the stopper end surface 20 e of the movable body 20 of the movable body 2 is in contact with the stopper portion 4 of the base 1.

  In FIG. 1, when an external force in the direction of the arrow P <b> 2 (switch-on direction) acts on the operation unit 21 of the movable body 2, the operation unit 21 of the movable body 2 is switched on from the switch-off position against the biasing member 3. The movable body 2 is moved from the switch-off position to the switch-on position by being pressed in the direction of the arrow P2 toward the position. As a result, the first movable contact piece 22a of the movable body 2 is in electrical contact with the first fixed contact piece 16a, and the second movable contact piece 22c of the movable body 2 is in electrical contact with the second fixed contact piece 16c. (See FIG. 5). In addition, about the external force which acts on the operation part 21, it may be operated with a finger | toe or it is good also as a form operated with power transmission members, such as an operating lever.

  As described above, according to the present embodiment, the sliding track of the movable body 2 is stabilized by the guiding action of the guide portion 5 of the base 1 and the guided portion 6 of the movable body 2. Thus, when the sliding track of the movable body 2 and thus the movable contact piece 22 is stabilized, the movable contact piece 22 is suppressed from rubbing and damaging the inner wall surface 12 of the base 1, and the generation of wear powder is suppressed. When the sliding trajectory of the movable contact piece 22 of the movable body 2 is stabilized in the cross section perpendicular to the slide direction, the movable body 2 and the movable contact piece 22 are suppressed from riding on the wear powder, It is possible to prevent the wear powder from being caught between the fixed contact pieces 16. Therefore, contact failure due to wear powder is suppressed, and the reliability of the sliding switch is improved.

  According to the present embodiment, the center line between the first movable contact piece 22a and the second movable contact piece 22c is coaxial with the center line of the operation portion 21 of the movable body 2 (center line PA of the slide hole 10). It is supposed to be arranged. For this reason, when the movable body 2 slides, an unreasonable load acting on the first movable contact piece 22a and the second movable contact piece 22c is reduced. Therefore, it is more advantageous to stabilize the sliding locus of the first movable contact piece 22a and the second movable contact piece 22c. Further, at the switch-off position, gaps 7a and 7c (see FIG. 3) are formed between the inner wall surface 12 forming the slide hole 10 of the base 1 and the movable contact piece 22 of the movable body 2. The first movable contact piece 22 a and the second movable contact piece 22 c can be prevented from rubbing the inner wall surface 12 of the base portion 1. Therefore, generation | occurrence | production of abrasion powder is suppressed.

  Further, according to the present embodiment, unlike the prior art, the movable body 2 does not have a structure in which an arm extends along a direction orthogonal to the center line PA. For this reason, the moment which acts on the movable body 2 can be suppressed, and displacement of the posture of the movable body 2 due to the influence of the moment is suppressed.

  According to the present embodiment, unlike the prior art, the movable body 2 does not have an arm shape extending along a direction orthogonal to the center line PA. For this reason, when a force is applied to the operation portion 21 of the movable body 2, the distance between the point of application of the force acting on the operation portion 21 and the first movable contact piece 22a and the second movable contact piece 22c can be made as small as possible. For this reason, it is suppressed that an excessive load is applied to the first movable contact piece 22a and the second movable contact piece 22c. Therefore, it is advantageous for improving the sliding posture of the first movable contact piece 22a and the second movable contact piece 22c.

  Furthermore, according to the present embodiment, the movable contact pieces 22 a and 22 c have a symmetrical shape while having a spring force, so that the axis of the movable body 2 is displaced from the center line PA of the slide hole 10. Even so, the movable body 2 can be displaced in the direction of the arrow X (see FIG. 5), and as a result, the contact pressure at which the first movable contact piece 22a elastically contacts the first fixed contact piece 16a of the base portion 1 and The contact pressure at which the second movable contact piece 22c elastically contacts the second fixed contact piece 16c of the base 1 can be balanced, and the switch function can be improved. Contact pressure refers to the pressure per unit area at the contact portion.

  According to the present embodiment, as shown in FIG. 6, the wear soot guide portion 8 is provided at the end portion close to the switch-off position in the length direction of the first fixed contact piece 16a and the second fixed contact piece 16c. It has been. The wear rod guide portion 8 is formed in the base portion 1 and has a wedge shape that becomes wider from the tip 8a of the wear rod guide portion 8 toward the base end 8c thereof. In this case, even if wear wrinkles occur, it is advantageous to guide the wear wrinkles in the direction of the arrow S (discrete direction) so that the wear wrinkles are separated from the protrusions 17. As a result, the wear soot is prevented from entering the contact portion between the protrusion 17 of the fixed contact piece 16 and the movable contact piece 22. Therefore, poor contact and poor conductivity due to wear flaws are suppressed. In addition, although the wear wrinkle guide part 8 is formed with the inner wall surface 12 of the base 1, you may form with the 1st fixed contact piece 16a and the 2nd fixed contact piece 16c itself.

Part 25.

  Here, as shown in FIG. 7, the movable body main body 20 includes a guided portion 6 </ b> B having a convex shape (square cross section). The convex guided portion 6B engages with the concave groove-shaped guide portion 5B of the base portion 1 to guide the movable body 2 along the center line PA. In this case, the guided portion 6B (square shape in cross section) extends along a direction parallel to the center line PA, and a plurality of guided portions 6B are provided so as to face each other at the corners of the quadrangular movable body 20.

  Since the plurality of convex guided portions 6B are provided at the corners of the movable body 20 as described above, when the movable body 2 is slid, the posture of the movable body 2 and thus the first movable contact piece 22a. The posture of the second movable contact piece 22c is stabilized both in the sliding direction and in the direction orthogonal to the sliding direction. Therefore, the sliding locus of the movable body 2 is stabilized. As a result, the sliding locus of the first movable contact piece 22a and the second movable contact piece 22c is stabilized. As a result, it is advantageous to suppress contact failure between the first fixed contact piece 16a and the first movable contact piece 22a and contact failure between the second fixed contact piece 16c and the second movable contact piece 22c. In this case, it is advantageous to suppress poor contact between the fixed contact piece 16 and the movable contact piece 22.

A plurality of convex guided portions 6 </ b> C are formed on the second side portion 25 of the movable body 20. The guided portion 6C is guided by the guide portion 5C of the base 1 and moves along a direction parallel to the center line PA. As in the first embodiment, at the switch-off position, a gap is formed between the inner wall surface that forms the slide hole 10 of the base 1 and the movable contact piece 22 (22a, 22c) of the movable body 2, The inner wall surface and the movable contact piece 22 (22a, 22c) are not in contact with each other by the gap.

[Example 4]
FIG. 10 shows a fourth embodiment. The present embodiment has the same configuration and effects as the first embodiment, and can stabilize the sliding locus of the movable body 2 and thus the movable contact piece 22 (22a, 22c). According to this embodiment, as shown in FIG. 10, the side close to the opening 11 of the base 1 is the switch-on position of the sliding switch, and the side far from the opening 11 is the switch-off position of the sliding switch. In a normal state, as shown in FIG. 10, the movable body 2 is urged in the direction of the arrow P1 by the spring force of the urging member 3, and is maintained at the switch-on position. In this switch-on position, as shown in FIG. 10, the stopper end surface 20 e of the movable body 20 of the movable body 2 is in contact with the stopper portion 4 of the base 1. In the switch-on position, as shown in FIG. 10, the first movable contact piece 22a of the movable body 2 is in electrical contact with the first fixed contact piece 16a, and the second movable contact piece 22c of the movable body 2 is in contact.

As a result, at the switch-off position, the first movable contact piece 22a of the movable body 2 is not in contact with the first fixed contact piece 16a via a gap, and the second movable contact piece 22c of the movable body 2 is second fixed. The contact piece 16c is not contacted via a gap .

[Reference Example 1]
11 to 14 show Reference Example 1 (Example 5 is a missing number) . This example has basically the same configuration and operational effects as the first embodiment, and can stabilize the sliding track of the movable body 2 and thus the movable contact piece 22 (22a, 22c) having a convex shape. In the following, different parts will be mainly described. 11 and 12 show a cross section along the center line PA of the slide hole 10 and show the switch-off position of the slide switch. 13 and 14 show a cross section orthogonal to the center line PA of the slide hole 10. The first movable contact piece 22a and the second movable contact piece 22c constitute a first guided portion that guides the movable body 2 in addition to having a switch contact piece function. The first inner wall surface 12 a constitutes a first guide part of the base 1. In the switch-off position (see FIG. 11), the first movable contact piece 22a is guided along the center line PA while being in contact with one first inner wall surface 12a of the pair of first inner wall surfaces 12a. The second movable contact piece 22c is in contact with the other first inner wall surface 12a and guided along the center line PA.

  As shown in FIG. 11, the movable contact pieces 22a and 22c constituting the first guided portion for guiding the movable body 2 have a C shape or an inverted C shape in cross section, and can be elastically deformed. For this reason, even when the movable contact pieces 22a and 22c move along the center line PA together with the movable body 2, the sliding area and the sliding resistance of the movable contact pieces 22a and 22c are small. Moreover, since the movable contact pieces 22a and 22c have a symmetric shape while having a spring force, that is, the movable contact pieces 22a and 22c have a plane symmetry or a plane symmetry through a virtual plane including the center line PA. Therefore, even when the center line of the movable body 2 is displaced in the arrow X direction with respect to the center line PA of the slide hole 10, the movable body 2 can be appropriately displaced in the arrow X direction. As a result, the contact pressure at which the first movable contact piece 22a elastically contacts one of the first inner wall surfaces 12a of the base 1 and the contact at which the second movable contact piece 22c elastically contacts the other first inner wall surface 12a of the base 1 are obtained. The pressure can be balanced as much as possible. Also in this sense, the wear of the first inner wall surface 12a can be reduced, which is advantageous for suppressing the generation of wear powder from the first inner wall surface 12a.

  As can be understood from FIG. 12, a dimensional difference ΔD is formed in a boundary region between the first inner wall surface 12 a (first guide portion) of the base 1 and the fixed contact pieces 16 a and 16 c of the base 1. When the distance between the two sets of first inner wall surfaces 12a is DA and the distance between the fixed contact pieces 16a and 16c is DB, the distance DA is set slightly longer than the distance DB due to the dimensional difference ΔD. As a result, the pressure at which the movable contact pieces 22a and 22c come into contact with the first inner wall surface 12a (first guide portion) of the base 1 (the contact pressure of the movable contact pieces 22a and 22c at the switch-off position) is F1. When the pressure at which 22a and 22c come into contact with the fixed contact pieces 16a and 16c of the base 1 (the contact pressure of the movable contact pieces 22a and 22c at the switch-on position) is F2, the relationship is F1 <F2. Thus, since the contact pressure F1 contacting the first inner wall surface 12a can be made smaller than F2, the excessive contact of the movable contact pieces 22a and 22c with the first inner wall surface 12a of the base 1 is further suppressed, and the first inner wall Wear of the wall surface 12a is suppressed, and generation of wear powder from the first inner wall surface 12a is suppressed.

  As shown in FIG. 13, in a cross section orthogonal to the center line PA, one direction is defined as an X direction, and a direction orthogonal to the X direction is defined as a Y direction. The X direction indicates the direction connecting the movable contact pieces 22a and 22c. The Y direction indicates a direction orthogonal to the direction connecting the movable contact pieces 22a and 22c. Since the movable contact pieces 22a and 22c have a spring force, if the movable contact pieces 22a and 22c are elastically brought into contact with the first inner wall surface 12a of the base 1 by using this spring force, the posture of the movable body 2 in the X direction. Can be restrained well.

  As shown in FIG. 13, a second guide portion 5 s is formed in a step shape on the second inner wall surface 12 c of the base portion 1. Since the second side 25 of the movable body 2 is in contact with the second guide portion 5s of the base 1 and guided along the center line PA, it functions as a second guided portion of the movable body 2. Since the second side portion 25 of the movable body 2 is in contact with the second guide portion 5s of the base portion 1, the posture of the movable body 2 can be constrained in the Y direction. As a result, the posture of the movable body 2 can be favorably restrained in the X direction and the Y direction, that is, in the direction orthogonal to the center line PA, and the movable body 2 and the movable contact piece 22 (22a, 22c) slide. The trajectory can be stabilized, contributing to the reduction of wear, which is advantageous in reducing wear powder.

According to this example , as can be understood from FIG. 13, the second side 25 (second guided portion) of the movable body 2 may be applied to the second guide portion 5 s of the base 1 for the constraint in the Y direction. . As for the restraint in the X direction, the movable contact pieces 22a and 22c (first guided portions) having a convex shape having a spring force may be elastically brought into contact with the first inner wall surface 12a (first guide portion) of the base 1. As a result, the tolerance range of the dimensional accuracy in the X direction of the movable body 20 and the movable contact pieces 22a and 22c can be expanded, which is advantageous in manufacturing. Further, as shown in FIGS. 13 and 14, gaps 71 f and 71 s are formed between the second inner wall surface 12 c of the base 1 and the second side 25 of the movable body 20. It is possible to contribute to the reduction of the friction area and the wear, which is advantageous in reducing wear powder.

According to this example , regarding the restraint in the X direction, if the movable contact pieces 22a and 22c having a spring force that can function as a guided portion are brought into elastic contact with the first inner wall surface 12a (first guide portion) of the base portion 1. The tolerance range of the dimensional accuracy in the X direction of the movable body 20 and the movable contact pieces 22a and 22c can be expanded.

It is guided along the center line PA in contact with the (first guide portion). The second movable contact piece 22c (first guided portion) is guided along the center line PA in contact with the other first inner wall surface 12a (first guiding portion). Since the convex movable contact pieces 22a and 22c have a spring force, the spring contact force is used to elastically contact the movable contact pieces 22a and 22c with the first inner wall surface 12a of the base 1 as in the fifth embodiment. Then, the posture of the movable body 2 in the X direction can be favorably restrained using the spring force. As a result, the sliding locus of the movable body 2 and the movable contact piece 22 (22a, 22c) is stabilized.

  Further, as shown in FIG. 15, the second side 25 of the movable body is slidably brought into contact with the convex second guide portion 5 s of the base 1 and is guided along the center line PA.

The piece 22c is in contact with the other first inner wall surface 12a (first guide portion) and guided along the center line PA. Therefore, the 1st movable contact piece 22a and the 2nd movable contact piece 22c function as a 1st guided part which guides the movable body 2 besides functioning as a switch contact piece.

  In the switch-off position, as shown in FIG. 16, the first sliding piece 28a is in contact with one second inner wall surface 12c (second guide portion) of the set of two second inner wall surfaces 12c, The second sliding piece 28c comes into contact with the other second inner wall surface 12c (second guide portion). Accordingly, the first sliding piece 28 a and the second sliding piece 28 c function as a second guided portion that guides the movable body 2. Here, the first sliding piece 28a and the second sliding piece 28c do not function as switch contact pieces because they do not electrically contact the fixed contact pieces 16a and 16c.

Also in this example , the first movable contact piece 22a, the second movable contact piece 22c, the first sliding piece 28a, and the second sliding piece 28c are bent in a C shape or an inverted C shape (see FIG. 18).
