The switch device 10 is a so-called tumbler switch (contact portion inversion structure switch), and is attached to a metal frame-shaped support (not shown). A three-way switch, which is a wiring device, is configured by attaching to the opening formed in the wall plate as a material using a holding metal fitting or a wiring box, and further covering the indoor side with a mounting plate and a switch cover. .

  The switch device 10 includes a switch main body 11 and a handle 12 that is an operation body that is swingably supported on the upper side of the switch main body 11 as a front side. In addition, hereinafter, the front side is the upper side (arrow X direction shown in FIG. 1), the back side is the lower side, and the longitudinal direction of the switch body 11 orthogonal to the front and back direction is the front side (arrow Y direction shown in FIG. 1) and the rear side. The width direction of the switch body 11 will be described as one side direction (direction perpendicular to the paper surface in FIG. 1) and the other side direction. The switch body 11 is composed of a substantially box-shaped case body 14 made of a synthetic resin such as a thermosetting resin with the upper side opened as a case opening 14a, and a composition such as a thermosetting resin covering the upper side of the case body 14. A resin cover 15 is provided, and the case body 14 and the cover 15 are fixed by a pair of front and rear fasteners 16 made of metal or the like, and a metal fitting housing portion 17 which is a housing space portion is formed inside.

  For example, four wire insertion openings 21 and two release holes (not shown) are formed on the lower surface of the case body 14. Inside the wire insertion opening 21, chain-like metal fittings 24 each having a bent leaf spring are arranged, and inside the release holes are release bodies (release buttons) (not shown) made of synthetic resin, respectively. ) Is arranged so that it can be moved up and down. The two chain fittings 24 located on the rear side are connected in combination with a common terminal 26, and the two chain fittings 24 located on the front side are respectively connected to terminals 27 (one of which is a load terminal). Only shown). For this reason, the electric wire inserted into the electric wire insertion port 21 located on the rear side is sandwiched between the chain fitting 24 and the common terminal 26 and connected in a chain manner and is electrically connected. Further, the electric wire inserted into the electric wire insertion port 21 located on the front side is sandwiched between the chain fittings 24 and the terminals 27 and connected in a chain manner and is electrically connected. Further, by inserting a jig such as a flathead screwdriver into the release hole and pushing the release body to deform the chain metal fitting 24, the chain connection is released and the connected electric wire can be removed.

  In addition, the common terminal 26 is provided with a movable piece bearing portion 31 that extends in a substantially central portion at the lower portion of the metal fitting housing portion 17 and is bent in a substantially V shape that expands upward. In addition, fixed contacts 33 and 33 as main body side contacts are formed on the terminals 27 and 27 so as to be opposed to each other in the front-rear direction.

  Further, a movable piece 41 which is a projecting piece is disposed opposite to the fixed contact 33. As shown in FIG. 3, the movable piece 41 is attached to a flat plate-shaped movable piece body 42 made of a conductive metal plate, and protrudes by caulking or the like on the upper end side in the longitudinal direction of the movable piece body 42. And a disc-shaped movable contact 44. The movable piece main body 42 has a base end portion 45 formed at the lower end portion which is a horizontal end portion, and both sides whose width dimension increases toward the base end portion 45 in the middle portion in the longitudinal direction. A pair of guide contact portions 46 are formed.

  The movable piece main body 42 abuts the base end portion 45 against the valley portion of the movable piece bearing portion 31, and is supported rotatably about the base end portion 45 as a fulcrum. The movable contact 44 comes into contact with either one of the fixed contacts 33 and 33 and the switch is closed, so that one of the terminals 27 and 27 and the common terminal 26 are electrically connected.

  Further, as shown in FIG. 1, the cover 15 of the switch body 11 has a substantially box-like shape whose lower surface is opened to communicate with the case opening 14a. An opening 49 having a small size is formed in the width direction. In addition, a switch body side protrusion 50 that is a protrusion is formed on the upper edge of the opening 49 so as to protrude inward. A space S is formed in the opening 49 between the case body 14 and the opening 49.

  In the space portion S, for example, when displaying the open / closed state of the switch of the switch device 10, various configurations and the like can be accommodated.

  As shown in FIGS. 1 and 2, the handle 12 includes a handle main body 51 formed of, for example, a synthetic resin, and is rocked with respect to the case body 14 by being press-fitted into the case body 14 from the opening 49. It is pivotally supported. The handle body 51 includes a main part 52 located in the center, a pair of operation parts 53 located before and after the main part 52, and a connection part 54 that connects the operation part 53 and the main part 52. The swing angle is regulated to a predetermined set swing angle α (for example, about 4 °) by the handle side protrusions 55 protruding on both side portions of the operation portion 53. That is, each handle side protrusion 55 comes into contact with the lower side of the switch body side protrusion 50 with the handle 12 swinging so that one of the operation parts 53 is on the upper side and the other is on the lower side. The handle 12 is restricted so as not to swing any further.

  At the center of the main part 52, a cylindrical storage cylinder part 56 is formed in which the vertical direction is the axial direction, the upper surface is closed, and the lower surface is opened. A coil spring 58 as a spring is formed in the storage cylinder part 56. Is inserted, and the lower end portion of the coil spring 58 is connected to the movable piece 41 via a movable piece receiver 59 which is a movable piece receiver as a restricting member. The main portion 52 is integrally provided with an engagement receiving portion (not shown) that serves as a fulcrum of the handle 12 with respect to the switch body 11.

  The storage cylinder portion 56 includes a spring storage portion 56a that stores and holds the coil spring 58, a flexible space forming portion 56b that expands and connects to the lower side of the spring storage portion 56a, and a flexible space forming portion 56b. And a money receiving portion 56c as a swing restricting portion that is connected to the lower side by expanding the diameter. Therefore, the storage cylinder portion 56 is formed so that the inner diameter dimension increases stepwise from the upper side to the lower side.

  The spring accommodating portion 56a farthest from the movable piece 41 has an inner diameter dimension substantially equal to the outer diameter dimension of the coil spring 58, and is configured so that the inserted coil spring 58 can be temporarily fixed. The spring storage portion 56a has a depth dimension that is about half of the length of the coil spring 58 in the used state (compressed state).

  The flexible space forming portion 56b is a portion that divides a flexible space portion 56d that can be deformed so that the lower end side of the coil spring 58 is sideward in the radial direction (thrust direction) intersecting the expansion and contraction direction. is there. The flexible space forming portion 56b may be arbitrarily enlarged as long as the flexible space 56d can be sufficiently bent in the radial direction so long as it forms at least the flexible space portion 56d. Alternatively, only the flexible space 56d may be formed in the space S without forming the flexible space forming portion 56b itself.

  The money receiving portion 56c closest to the movable piece 41 has an inner diameter dimension of about 1.2 to 1.5 times, for example, with respect to the spring accommodating portion 56a, and the movable piece receiving piece 59 is slidably fitted therein. Match. In other words, the money receiving portion 56c is formed to have a size that allows play in the swinging direction of the handle 12 with respect to the movable piece money receiving 59.

  In addition, the coil spring 58 has an upper end side stored in the spring storage portion 56a, a lower end side stored in the flexible space forming portion 56b, and a lower end portion positioned at the upper portion in the money receiving storage portion 56c. The coil spring 58 is a spring wound with an elastically deformable metal wire, and constitutes an elastic body that elastically expands and contracts in the axial direction and can also be elastically deformed in a direction inclined from the axial direction. is doing. The coil spring 58 constitutes a contact portion reversing mechanism and generates contact force of the contact portion.

  The movable piece receiver 59 is joined to the movable piece 41 due to buckling of the coil spring 58 or disturbance of winding due to a load by giving rigidity to the lower end side of the coil spring 58 connected to the movable piece 41. Or, it is for preventing abnormal operation due to excessive bending of the coil spring during the reversing operation of the handle 12. The movable piece receiver 59 may be, for example, a box shape formed by press molding, casting, forging, or the like, or a fitting shape that is almost housed on the inner diameter side of the coil spring 58. In this embodiment, as shown in FIG. In addition, a substantially rectangular plate-shaped base portion 62 and a pair of arm portions 63 that are bent from both side portions of the base portion 62 are formed by a member that can ensure appropriate rigidity, such as metal or synthetic resin.

  Each arm portion 63 has a width dimension that decreases linearly or via a corner portion toward the tip side, which is the lower side, and a groove-shaped notch portion such as a triangle shape or a U shape is formed at the tip portion. A guide portion 64 is formed. Then, the guide contact portions 46 on both sides of the movable piece 41 are brought into contact with or engaged with the guide portions 64 on both sides, and the movable contact 44 is positioned between the guide portions 64 on both sides in this state. It is supposed to be. Further, the base 62 is formed with a spring fitting portion (spring guide) 65 for temporary fixing protruding upward and projecting cylindrically upward. The outer diameter of the spring fitting portion 65 is slightly larger than the inner diameter of the coil spring 58, and the lower end portion of the coil spring 58 is fitted and held.

  Here, various mechanisms for swinging the movable piece 41 in response to the swing of the handle 12, that is, the size of the fixed contact 33, the movable piece 41, the storage cylinder portion 56, the coil spring 58, or the movable piece receiver 59, etc. The dimensions such as the position and the position are set so as to operate within a range not less than the set swing angle α of the handle 12. That is, the fixed contact 33, the movable piece 41, the storage cylinder portion 56, the coil spring 58, the movable piece receiver 59, etc. can swing the handle 12 larger than the set swing angle α, for example α × 1.1˜ Although each dimension and position are set so as to be able to swing at an angle of about 1.3, the swing angle of the handle 12 is restricted to the set swing angle α by the contact of the protrusions 50 and 55. It is configured as follows. By setting the conditions for the space within the switch main body 11 that can be stored, these numerical values can be naturally derived as appropriate.

  For example, in order to reliably perform the reversing operation such as turning on and off of the switch device 10 by the reversing operation of the handle 12, the money receiving portion 56 c has a neutral point of this operation during the reversing operation of the handle 12 as shown in FIG. Set so that the movable piece 41 is pushed from the neutral position to the opposite side by pushing the movable piece receiver 59 at a position where the set swing angle α is advanced to the opposite side, for example, about 1/2 to 3/5. To do.

  In the assembling process of the switch device 10, first, the chain bracket 24, the release body, the common terminal 26, and the terminal 27 that is a load terminal are assembled in the case body 14. Next, the upper end side of the coil spring 58 is inserted and fixed in the storage cylinder portion 56 of the handle 12, the spring fitting portion 65 of the movable piece receiver 59 is inserted into the lower end side of the coil spring 58, and the movable piece receiver With the guide contact portion 46 of the movable piece 41 fitted to the guide portion 64 of each arm portion 63 of the gold 59, the handle 12, coil spring 58, movable piece receiver 59 and The movable piece 41 is integrally press-fitted from the opening 49. In this state, the cover 15 is combined with the case body 14 and fixed with the pair of stoppers 16, and the assembly of the switch device 10 is completed. Further, the switch device 10 is attached to a support (not shown), attached to a wall surface using a wiring box or the like, and further, the interior side is covered with an attachment plate and a switch cover to constitute a one-piece switch.

  In this state, the operating portion 53 of the handle 12 is pushed through the switch cover and the handle 12 is swung to push the movable piece 41 through the coil spring 58 and the movable piece receiver 59 to rotate. The movable contact 44 is brought into contact with either one of the fixed contacts 33 and 33, and the circuit is switched.

  Specifically, when the handle 12 is swung as shown in FIG. 1, the right handle-side protrusion 55 in the drawing is positioned above the left handle-side protrusion 55 in the drawing so that the switch body side By contacting the protrusion 50, the swing of the handle 12 is restricted to a predetermined set swing angle α. At this time, the upper end side of the coil spring 58 is inclined to the swing side of the handle 12 (left side in the figure) with respect to the lower end side, so that the movable piece 41 is moved to the movable piece bearing portion via the movable piece receiver 59. A load is applied in a direction to contact 31 and the lower end side thereof is curved radially toward the swinging side of the handle 12 in the flexible space 56d to move the movable contact 44 of the movable piece 41 to the fixed contact 33 on the right side. Give the load to press. That is, as shown in FIG. 5, the load F of the coil spring 58 is a load F1 in a direction in which the movable piece 41 is brought into contact with the movable piece bearing portion 31, and the movable contact 44 of the movable piece 41 is moved to the fixed contact 33 on the right side. And a load F2 to be pressed. The deformation of the lower end portion of the coil spring 58 is restricted by the movable piece receiver 59 coming into contact with the right side in the receiver storage portion 56c.

  From this state, when the left side in FIG. 1 of the operating portion 53 of the handle 12 is pressed through the switch cover, the movable piece receiver 59 receives the handle 12 as the handle 12 becomes neutral as shown in FIG. The movable contact 41 is separated from the right fixed contact 33 by being pressed by the gold storage portion 56c and pivoting the movable piece 41 relative to the right in the drawing with the movable piece bearing 31 as a base point. In this state, the movable piece 41 is in a state in which the upper end side is inclined to the right side with respect to the lower end side by the bias of the coil spring 58. Further, when the left side of the operation portion 53 of the handle 12 is pressed through the switch cover, as shown by an imaginary line and a solid line in FIG. When the position advances to the opposite side by about 2 to 3/5, the movable piece receiver 59 is pressed by the receiver storage portion 56c to the neutral position, and the lower end side of the coil spring 58 curved to the right side is The flexible space 56d is switched so as to bend to the left side, and the urging is switched so that the upper end side of the movable piece 41 is inclined to the left side with respect to the lower end side. Abutting on the left side in the gold storage portion 56c, the bending of the coil spring 58 to the left side on the lower end side is restricted. Thereafter, as shown in FIG. 4 (c), when the handle 12 swings to the right side, the handle-side protrusion 55 on the left side of the handle 12 is positioned above the handle-side protrusion 55 on the right side in the figure. By contacting the switch body side protrusion 50, the swing of the handle 12 is restricted to a predetermined set swing angle α.

  As described above, according to the switch device 10 of the above-described embodiment, the handle-side protrusion 55 provided on the handle 12 is provided on the front side of the switch body 11 when the handle 12 is swung. By restricting the swing angle of the handle 12 by abutting 50, variation in the swing angle of the handle 12 can be suppressed, and a configuration for restricting the swing angle of the handle 12 is provided inside the switch body 11. There is no need to provide it, and the space S can be secured inside the switch body 11.

  For this reason, when two or more switch devices 10 are installed on the same mounting frame, the tilt of the handle 12 is unified and the appearance of the handle 12 is not deteriorated, and the play of the handle 12 is made uniform. There is no sense of incongruity.

  In addition, depending on the type of the switch device 10, there may be a configuration in which a lighting device or the like is attached to the handle 12 to form a display unit that displays the open / closed state of the switch on the handle 12 (switch cover). By securing the space portion S inside 11, it is possible to incorporate a lighting configuration in the space portion S, and it is possible to deal with a configuration with an illumination device without causing an increase in the size of the switch device 10 or the like.

  Further, since the switch body-side protrusion 50 is located on the front side of the switch body 11, it is difficult for dust to enter the switch body 11 from the opening 49, and malfunctions or continuity failures caused by the entry of dust. Can also be prevented.

  In addition, the flexible space portion 56d for obtaining the operating range of the movable piece 41 in which the movable contact 44 and the fixed contacts 33 and 33 can come into contact with each other by deforming the back side of the coil spring 58 into thrust is provided on the back surface of the handle 12. By providing them on the side, even when dimensional tolerances, positions, etc., vary in the movable contact 44 and the fixed contacts 33, 33, etc., these variations can be absorbed by the deformation of the coil spring 58 in the flexible space 56d. Thus, reliable contact between the movable contact 44 and the fixed contacts 33 and 33 can be obtained.

  Furthermore, by restricting the swing position of the movable piece receiver 59 fitted to the receiver receiving portion 56c on the back side of the handle 12 by the receiver receiving portion 56c, the back side of the coil spring 58 is more than necessary in the thrust direction. Can be prevented from following the reversing operation of the handle 12 while being deformed, and the movable piece 41 is reliably followed to the reversing operation of the handle 12 via the coil spring 58 and the movable piece receiver 59. be able to.

  The small movement of the handle 12 can be reliably transmitted to the movable piece 41, and the movable contact 44 of the movable piece 41 can be moved largely by the small movement of the handle 12, so that the so-called contact gap and contact follow can be secured greatly. Even a large switch cover with a small angle can provide a switch that operates reliably. Further, it is not necessary to increase the processing accuracy more than necessary, the manufacturing cost can be reduced, the movable piece 41 and the like need not be enlarged, and the switch device 10 can be prevented from being enlarged.

  In the above-described embodiment, the engagement receiving portion serving as a fulcrum of the handle 12 can be configured and attached as a separate component from the handle main body 51.

  Moreover, the switch device of the present invention can be applied to an exposed switch that is attached to a wall or a construction material directly using a wood screw or the like in addition to an embedded switch that is attached to a switch box or the like.
