Description

  The present invention relates to a switch plate used to install a switch having an operation handle attached to a switch body in a manner that a rear portion is embedded in a construction hole formed in a construction surface.

  Conventionally, as this type of switch plate, as shown in FIG. 9, a rectangular mounting window 15 in which a switch body 3 having a contact device (not shown) is mounted in a rectangular parallelepiped container 6 is provided. A plate frame 11 that is fixed by bringing the back surface into contact with the work surface over the entire circumference around the work hole in a manner that the rear portion of the switch body 3 is embedded in a work hole (not shown) formed in the work surface. The one with is known. A decorative plate 12 (see FIG. 2) having an exposure window 22 for exposing the operation handle 2 attached to the front surface side of the switch body 3 is detachably mounted on the front surface side of the plate frame 11. And the plate frame 11 constitute a switch plate 1 (see, for example, Patent Document 1).

  Here, the switch SW shown in FIG. 9 is a so-called wide handle switch in which the operability is improved by forming the operation surface 2 a of the operation handle 2 to be larger than the front surface of the switch body 3. This type of switch SW is generally mounted on the mounting window 15 by inserting the front end of the switch body 3 with the operation handle 2 removed from the back side of the plate frame 11 into the mounting window 15. After the plate frame 11 is attached to the construction surface, the operation handle 2 is installed on the front side of the switch body 3.

  By the way, the plate frame 11 described in Patent Document 1 is provided with mounting holes 19 (see FIG. 2) in which switch bodies 3 having unit dimensions that can be mounted on a plurality of mounting windows 15 (three in FIG. 9) can be mounted. However, a plurality of sets are arranged in parallel on the inner surface of the mounting window 15. Here, when the above-described (wide handle type) switch SW is mounted on the switch plate 1, the operation handle 2 can be mounted according to the maximum number of switch bodies 3 of unit dimensions that can be mounted on the mounting window 15. The mounting position is fixed.

  That is, in the plate frame 11 on which up to three switch bodies 3 of unit dimensions can be mounted on the mounting window 15, when one or two switches SW are mounted, each operation handle 2 is attached to the switch body 3 to be mounted. When the three switches SW are mounted at the mounting position where the center in the longitudinal direction of the mounting window 15 coincides with that of the mounting window 15, the central operation handle 2 is connected to the switch body 3 to be mounted as shown in FIG. The operation handle 2 at both ends is attached to the attachment position where the center in the longitudinal direction of the attachment window 15 coincides, and the center in the longitudinal direction of the attachment window 15 is outside the center of the switch body 3 to be attached (that is, FIG. ) At the upper end of the operation handle 2 and at the lower end of the operation handle 2 at the lower end of FIG. 9A.

  Here, when three switches SW are mounted, the relative positions of the switch body 3 and the operation handle 2 differ depending on the mounting position of the switch body 3 with respect to the plate frame 11 as described above. An operation handle 2 that can be used in common is provided. As shown in FIG. 10A, the operation handle 2 has a plurality of engaging projections 26 for mounting on the switch body 3 in the rear side, in the direction in which the switch body 3 is juxtaposed. The protrusion 26 is attached to the reversing handle 9 using the engaging protrusion 26 determined for each mounting position of the switch body 3. Here, the operation handle 2 is also positioned in the direction in which the switch body 3 is juxtaposed.

  However, according to the above-described configuration, the operation handle 2 can be attached to the switch body 3 even if the wrong engaging protrusion 26 is used in each switch SW. For example, the switch is attached to the lower end in FIG. In the operation handle 2 to be operated, the wrong engaging protrusion 26 is used to displace the operation handle 2 from the attachment position shown in FIG. 10 (a) toward the center switch body 3 side, as shown in FIG. 10 (b). The switch main body 3 to be attached and the attachment window 15 may be attached at a position where the centers in the longitudinal direction coincide with each other. If the operation handle 2 is attached with a deviation from the attachment position, it is necessary to reattach the operation handle 2 to the correct attachment position, which is troublesome.

On the other hand, as shown in FIG. 11, a mounting frame 28 having a rectangular opening 27 to which the switch body 3 is mounted and fixed to the construction surface in such a manner that the rear part of the switch body 3 is embedded in the construction hole. In order to make it difficult to cause a construction error in which the operation handle 2 is mounted with a deviation from the mounting position, there has been proposed one having a mark portion 29 indicating the mounting position of the operation handle 2 around the opening 27 (for example, Patent Document 2). Here, the attachment frame 28 is attached so that the most part except for both ends in the longitudinal direction falls within the range of the construction hole, and the width dimension is set to be the same as that of the construction hole. Therefore, as described above, in a state where the operation handle 2 formed with a size larger than the front surface of the switch body 3 is attached, most of the operation handle 2 except for both ends in the longitudinal direction is covered with the operation handle 2.
JP 2006-202716 A (page 7) JP 2003-219532 A (page 4-5, FIG. 6)

  By the way, in the attachment frame 28 described in Patent Document 2, the mark portion 29 is covered with the operation handle 2 when the operation handle 2 is attached. Therefore, after the operation handle 2 is attached, the operation handle 2 is displaced from the attachment position. It cannot be confirmed whether it is attached or not. Therefore, when a plurality of operation handles 2 are attached, if one operation handle 2 is attached with a deviation from the attachment position, the other operation handle 2 is not noticed that the operation handle 2 is displaced from the attachment position. 2 is also mounted with a deviation from the mounting position, and as a result, there is a possibility that a work for reattaching the plurality of operation handles 2 to the correct mounting position is required, and the workability of mounting the operation handle 2 is poor. There is.

  The present invention has been made in view of the above-described reasons, and provides a switch plate that is less likely to cause a construction error in which an operation handle is displaced from an attachment position and has good workability in attaching the operation handle. Objective.

  According to the first aspect of the present invention, there is provided a mounting window in which a switch body having a contact device is mounted in a rectangular parallelepiped container, and the rear portion of the switch body is embedded in a construction hole formed in the construction surface. The plate frame that is fixed with the rear surface in contact with the construction surface over the entire circumference of the switch, and the exposure that exposes the operation handle attached to the front side of the switch body, with the operation surface being larger than the front surface of the switch body And a decorative plate that is attached to the front side of the plate frame, and the plate frame has a plurality of mounting portions on the mounting window, each of which can be mounted with a plurality of unit dimensions that can be mounted on the mounting window. The installation position where the operation handle can be attached is determined according to the maximum number of switch bodies of unit dimensions that can be attached to the attachment window, and the outer frame part equipped with attachment means for attaching the decorative plate Has around the mounting position, the position display means for indicating the installation position, characterized by having an extension of the boundary line of the mounting position in the outer frame portion.

  According to this configuration, since the plate frame has the position display means indicating the attachment position where the operation handle can be attached, the construction error that the operation handle is attached to be shifted from the attachment position by attaching the operation handle according to the position display means. Is less likely to occur. In addition, since the position display means is provided on the outer frame around the mounting position, it is not covered with the operation handle even when the operation handle is attached, and even after the operation handle is attached, It can be confirmed whether or not the handle is attached with a deviation from the attachment position. Therefore, when attaching a plurality of operation handles, it is possible to avoid mounting other operation handles from being shifted from the mounting position without noticing that one operation handle is shifted from the mounting position. In addition, it is easier to reattach the operation handle after attaching a plurality of operation handles and then reattaching the plurality of operation handles to the correct mounting position. To do.

  According to a second aspect of the present invention, in the first aspect of the invention, the position display means includes a number display unit that represents the maximum number of operation handles that can be attached when the operation handles are attached to the corresponding attachment positions. It is characterized by having.

  According to this configuration, by attaching the operation handle in accordance with the number display unit that represents a number corresponding to the number of operation handles to be attached, it is possible to avoid a construction error in which the operation handle is installed in the wrong position. Installation workability is further improved.

  According to a third aspect of the present invention, in the second aspect of the present invention, the position display means has a linear line display section along a boundary line of the attachment position for each of the number display sections.

  According to this configuration, the attachment position indicated by the number display unit is clarified by the line display unit, so that it is possible to avoid erroneous reading of the number display unit. Further, since the boundary line of the attachment position is clarified by the line display portion, the operation handle can be easily aligned when the operation handle is attached.

  According to a fourth aspect of the present invention, in the second or third aspect of the present invention, the mounting window includes a predetermined odd number of three or more mounting portions arranged side by side, and the position display means is mounted. In the window, a center mark other than numerals is provided at the center of the switch body in the parallel arrangement direction, and the number display portion is provided at a position other than the center mark.

  According to this configuration, since there is a center mark other than numbers at the center of the mounting window in the mounting direction in the mounting window, compared to the case where the number display part is provided on the extended line of the boundary line of all mounting positions. Thus, the display of the mounting position by the position display means is simplified, and there is an advantage that the installer can easily understand the mounting position of the operation handle.

  According to the present invention, by attaching the operation handle in accordance with the position display means provided on the extension line of the boundary line of the attachment position in the outer frame portion of the plate frame, it becomes difficult to cause a construction error in which the operation handle is displaced from the attachment position. In addition, since the position display means is provided on the outer frame around the mounting position, it is confirmed whether or not the operating handle is mounted out of the mounting position even after the operating handle is mounted. This improves the workability of attaching the operation handle.

  In each of the following embodiments, as shown in FIG. 2, the switch plate 1 is a switch SW (so-called wide handle) whose operability is improved by forming the operation surface 2a of the operation handle 2 larger than the front surface of the switch body 3. The switch plate 1 used for attaching a shape switch) to a construction hole (not shown) formed in a construction surface (not shown) is illustrated. In the following description, the switch plate 1 and the switch SW are assumed to be attached to the construction surface in the direction of FIG. 2B, and the vertical direction of FIG. The mounting direction of the switch SW is not limited to this example.

  The configuration of the switch SW will be described below.

The switch body 3 is housed, and the operation handle 2 is detachably attached to the front side of the switch body 3. Each side surface along the longitudinal direction of the body 4 is provided with a pair of assembly protrusions 7 arranged in the longitudinal direction of the body 4, and an assembly piece 8 extends rearward from the rear edge of the cover 5. The body 4 and the cover 5 are coupled by engaging the assembly protrusion 7 with the assembly hole 8 a provided in the assembly piece 8.

  A reversing handle 9 (see FIG. 9B) for opening and closing the contact device is pivotally attached to the cover 5 so as to be swingable with respect to an opening window (not shown) opened in the center of the front wall of the cover 5. As the reversing handle 9 swings, the contact device opens and closes. The operation handle 2 is detachably attached to the front side of the reversing handle 9, and when the operating handle 2 is swung, the reversing handle 9 is swung to open and close the contact device. Both the reversing handle 9 and the operation handle 2 are made of synthetic resin, and the coupling claws 10 that project from the respective end surfaces of the reversing handle 9 in the swinging direction (left-right direction) project toward the back side of the operation handle 2. The operating handle 2 is attached to the reversing handle 9 by engaging with an engaging claw 26a (see FIG. 10) provided at the tip of the engaging protruding piece 26 (see FIG. 10).

  Specifically, at least a pair of engaging protrusions 26 are provided so as to be opposed to each other in the left-right direction, and the engaging claws 26 a are extended from the front ends of the opposing engaging protrusions 26 so as to approach each other. A pair of coupling claws 10 are arranged side by side in the vertical direction on each end face of the reversing handle 9, and are attached to the reversing handle 9 so that the reversing handle 9 is sandwiched between the engaging protrusions 26 with which the operation handle 2 is paired. In this state, the operation handle 2 is attached to the reversing handle 9 by each pair of coupling claws 10 being hooked on the respective engagement claws 26. Here, the operation handle 2 is also positioned in the vertical direction.

(Embodiment 1)
The switch plate 1 of the present embodiment includes a plate frame 11 that is attached to an embedding box (not shown) that holds the switch body 3 and is disposed inside the construction hole, and a plate on the front side of the plate frame 11. The decorative plate 12 is mounted so as to cover the frame 11.

  As shown in FIG. 1A, the plate frame 11 is formed in a rectangular frame shape by a pair of vertical frames 13 facing each other and a pair of horizontal frames 14 connecting the ends of the pair of vertical frames 13. A rectangular mounting window 15 to which the switch body 3 is mounted is provided at a portion surrounded by the vertical frame 13 and the horizontal frame 14. Here, in the pair of horizontal frames 14 facing in the vertical direction, which is the longitudinal direction of the mounting window 15, a box screw for mounting the plate frame 11 to the embedding box embedded in the construction surface at the center in the longitudinal direction. A long hole 16 is inserted therethrough (not shown). On both sides of the long hole 16, a part of a well-known clip metal fitting (not shown) for holding a construction material (not shown) such as a wall panel constituting the construction surface between the plate frame 11 is locked. A pin 17 is provided through the pin. Furthermore, screw insertion holes 18 through which screws (not shown) for directly attaching the plate frame 11 to the construction surface are formed on the opposite side of the attachment window 15 with respect to the respective pin holes 17. Yes.

  In addition, as shown in FIG. 2, three pairs of mounting holes 19 arranged in the longitudinal direction of the vertical frame 13 are arranged in three in the vertical direction at a portion of each vertical frame 13 facing the mounting window 15. Yes. Each pair of mounting holes 19, together with each pair of mounting holes 19 facing each other, can mount a switch body 3 formed in one-third dimension in the longitudinal direction of the mounting window 15 (hereinafter referred to as “unit dimension”). The mounting part is configured. Here, mounting claws 20 project from the side surfaces of the body 6 of the switch body 3 in the left-right direction at positions corresponding to the mounting holes 19, and the switch body so that the mounting claws 20 fit into the mounting holes 19. 3 is inserted into the mounting window 15 from behind the plate frame 11, so that the switch body 3 is mounted on the mounting window 15. Here, since three sets of mounting holes 19 are juxtaposed in the longitudinal direction of the mounting window 15, a maximum of three switch bodies 3 of unit dimensions can be mounted on the mounting window 15. In addition, on one side surface in the left-right direction of the body 6 of the switch body 3, flexibility is imparted to a portion where the mounting claws 20 are projected by providing a pair of grooves 21 (see FIG. 9B). The switch main body 3 can be detached from the plate frame 11 by releasing the engagement between the mounting claw 20 and the mounting hole 19 by bending this portion.

  The decorative plate 12 is formed in a rectangular frame shape as shown in FIG. 2 and exposes the operation handle 2 attached to the switch body 3 through an exposure window 22 opened in a rectangular shape at the center. Both the plate frame 11 and the decorative plate 12 are made of synthetic resin, and locking pieces (not shown) protruding rearward from the four corners on the back of the decorative plate 12 are formed at the four corners of the plate frame 11. The decorative plate 12 is mounted on the plate frame 11 by being inserted and locked in the locking holes 23 (see FIG. 1A) as mounting means. Further, reinforcing ribs 24 are provided upright along the periphery of the opening of the mounting window 15 at a position closer to the mounting window 15 than the locking hole 23 in the width direction of each vertical frame 13.

  On the other hand, the operation handle 2 known as a wide handle in which the operation surface 2a is formed larger than the front surface of the switch main body 3 is used for three pieces used when the three switch main bodies 3 having unit dimensions are mounted on the plate frame 11 described above. Operation handle 2 (hereinafter referred to as “reference size operation handle”), and the vertical size of the operation handle 2 is 1.5 times that of the reference size operation handle 2, and the unit size switch is provided on the plate frame 11 described above. The switch body of the unit size is provided in the above-described plate frame 11 and has three dimensions in the vertical direction as compared with the operation handle 2 for two used for mounting two main bodies 3 and the operation handle 2 of the standard dimension. There is one operation handle 2 used when one 3 is mounted. That is, one operation handle 2 is formed to have a size that fills the exposure window 22 of the decorative plate 12 described above, and two operation handles 2 are arranged side by side so that the decorative plate 12 is provided. The operation handle 2 for three (reference size) is formed in a size to fill the exposure window 22 of the decorative plate 12 by arranging three operation handles 2 in parallel. is there.

  By the way, the switch plate 1 of the present embodiment has a mounting position where the operation handle 2 can be mounted according to the maximum number of switch bodies 3 of unit dimensions that can be mounted on the mounting window 15. That is, since the plate frame 11 of the present embodiment is formed to a size that allows mounting of up to three switch bodies 3 of unit dimensions in the mounting window 15, for example, when three switches SW are mounted, FIG. ), The central operation handle 2 is mounted at the mounting position where the center of the switch body 3 to be mounted coincides with the center in the vertical direction, and the operation handles 2 at both ends have the vertical center at the top and bottom of the switch body 3 to be mounted. It is attached to an attachment position that is outside the center of the direction (that is, upward in the upper end operation handle 2 and lower in the lower end operation handle 2). In addition, the operation handle 2 used at this time is the operation handle 2 for three (reference dimensions) described above.

  As described above, in the three operation handles 2, the relative positions of the switch body 3 and the operation handle 2 differ depending on the mounting position of the switch body 3 with respect to the plate frame 11, but in this embodiment, all the switch bodies 3 An operation handle 2 that can be used in common with 3 is adopted. Specifically, each pair of engaging protrusions 26 provided on the back side of the operation handle 2 is arranged in parallel in three directions, and the operation handle 2 is determined for each mounting position of the switch body 3. It is attached to the reversing handle 9 using the engaging protrusion 26. Here, the engaging claw 26 a provided in the central engaging projection piece 26 is formed so that the vertical dimension is larger than the interval between the pair of coupling claws 10. In the joint claw 26a, the vertical dimension is formed smaller than that of the engagement claw 26a of the central engagement projection piece 26. The central operation handle 2 is attached to the reversing handle 9 using the engagement claw 26a of the central engagement projection piece 26. In the operation handle 2 at both ends, the engagement projection piece 26 at either end is attached. The engaging claw 26a and the engaging claw 26a of the central engaging projection 26 are attached to the reversing handle 9.

  Here, in the operation handle 2 at both ends, the engagement projection piece 26 on one end side is used for coupling with the reversing handle 9, and the engagement projection piece 26 on the other end side is outside the mounting window 15 of the plate frame 11. The protruding protruding protrusion 26 is inserted into the pinching metal fitting hole 17 of the plate frame 11 so as not to interfere with the plate frame 11.

  When two switches SW are mounted, the switch body 3 is mounted with the center of the mounting window 15 being opened as shown in FIG. 3C, and both the operation handles 2 are connected to the switch body 3 to be mounted. It is attached at the attachment position where the centers in the vertical direction coincide. The operation handle 2 used at this time is the two operation handles 2 described above. Furthermore, when one switch SW is mounted, the switch body 3 is mounted at the center of the mounting window 15 as shown in FIG. 4 (c), and the operation handle 2 is mounted as shown in FIG. 4 (b). The target switch body 3 and the center in the vertical direction are attached at the attachment position. The operation handle 2 used at this time is the one operation handle 2 described above.

  By the way, the plate frame 11 has an outer frame portion 30 around the mounting position of the operation handle 2, and the locking hole 23 is formed in the outer frame portion 30. Here, since the operation handle 2 is arranged so as to fit between a pair of ribs 24 provided on both the vertical frames 13 in the left-right direction, each vertical frame 13 has a mounting window in the left-right direction with respect to the ribs 24, respectively. The part opposite to 25 and the rib 24 form the outer frame part 30. Since the outer frame portion 30 is provided around the attachment position, the outer handle portion 30 is not covered by the operation handle 2 even when the operation handle 2 is attached.

  Here, the switch SW attaches the switch body 3 to the mounting window 15 by inserting the front end portion of the switch body 3 with the operation handle 2 removed from the back side of the plate frame 11 into the mounting window 15. After the frame 11 is attached to the construction surface, the operation handle 2 is installed on the front side of the switch body 3. However, in this type of switch SW, the front surface of the switch body 3 is hidden by the operation handle 2, so that the installation position of the operation handle 2 is difficult to understand when the operation handle 2 is installed, and the operation handle 2 is displaced from the installation position. There is a possibility of causing installation errors.

  Accordingly, as shown in FIG. 1A, the plate frame 11 of the present embodiment has marks M1 to M3 as position display means for indicating the mounting position of the operation handle 2 on the outer frame portion 30 around the mounting position. is doing. Each of the marks M1 to M3 is provided on an extension of the boundary line of the mounting position in each vertical frame 13. Here, three marks M <b> 1 to M <b> 3 are arranged in parallel along the longitudinal direction of the attachment window 15 on each rib 24. Each of the marks M1 to M3 is given by forming an uneven shape on the vertical frame 13 using engraving. However, the present invention is not limited to this example, and the marks M1 to M3 may be given by, for example, laser printing or printing. Here, of the three marks M1 to M3, the round marks M1 and M3 at both ends are the boundary lines of the mounting position of the operation handle 2 when three switches SW are mounted as shown in FIG. The triangular mark M2 at the center is provided on the extension line of the boundary of the mounting position of the operation handle 2 when two switches SW are mounted as shown in FIG. It has been.

  Therefore, when three switches SW are mounted, the operation handle 2 is adjusted so that the edge of each operation handle 2 is aligned with either one of the marks M1 and M3 in the vertical direction according to the marks M1 and M3 at both ends. By attaching, it becomes difficult to produce the construction mistake in which the operation handle 2 is displaced from the attachment position. When two switches SW are mounted, the operation handle 2 is attached by attaching the operation handle 2 so that the edge of each operation handle 2 is aligned with the center mark M2 in the vertical direction according to the center mark M2. Installation errors that are shifted from the mounting position are less likely to occur.

  In addition, since the marks M1 to M3 are provided on the outer frame portion 30 that is not covered with the operation handle 2 even when the operation handle 2 is attached, the operation handle 2 is attached even after the operation handle 2 is attached. It can be confirmed whether or not the mounting position is shifted from the mounting position. Therefore, when a plurality of operation handles 2 are attached, it is possible to avoid a situation in which another operation handle 2 is attached with a deviation from the attachment position without noticing that one operation handle 2 is displaced from the attachment position. . As a result, it is possible to attach the operation handle 2 more easily than attaching the plurality of operation handles 2 and then attaching the plurality of operation handles 2 to the correct attachment position. Improved workability.

  When only one switch SW is mounted, only one operation handle 2 is attached to the center of the plate frame 11. Therefore, even if there is no mark, the operation handle 2 is attached with a deviation from the attachment position. There is little to be done. However, as shown in FIG. 4A, when a projection 25 representing the operation position of the operation handle 2 is provided at the center of each end portion in the swing direction of the operation surface 2a of the operation handle 2, The operation handle 2 may be attached according to the center mark M2 so that the protrusion 25 is aligned with the center mark M2.

(Embodiment 2)
As shown in FIG. 5, the switch plate 1 of the present embodiment represents the maximum number of the operation handles 2 that can be attached when the position display means attaches the operation handles 2 at the corresponding attachment positions. The point which has the number display parts N1-N3 is different from the plate 1 for switches of Embodiment 1. FIG. In the example of FIG. 5, number display portions N <b> 1 to N <b> 3 are provided on the ribs 24 instead of the marks M <b> 1 to M <b> 3 shown in the first embodiment. Other configurations and functions are the same as those of the first embodiment. 5A to 5D, the plate frame 11 without the switch SW, the plate frame 11 with the three switches SW installed, the plate frame 11 with the two switches SW installed, and the switch SW, respectively. The plate frame 11 which mounted | wore 1 is shown.

  That is, in this embodiment, as shown in FIG. 5B, the number display indicated as “3” on the extended line of the boundary of the mounting position of the operation handle 2 when three switches SW are mounted. When the two switches SW are mounted as shown in FIG. 5 (c), the number display portion displayed as “2” is displayed on the extension of the boundary of the mounting position of the operation handle 2 when the portions N1 and N3 are provided. N2 is provided.

  According to this configuration, when three switches SW are mounted, the operation handle 2 may be mounted according to the number display portions N1 and N3 displayed as “3”, while on the other hand, when two switches SW are mounted. In this case, it is only necessary to attach the operation handle 2 in accordance with the number display portion N2 displayed as “2”, and the position display means to be used can be easily distinguished from among the plurality of position display means. Therefore, it is possible to easily avoid a construction mistake that makes the installation position of the operation handle 2 wrong, and the workability of installation of the operation handle 2 is further improved.

  In addition, as shown in FIG. 6, linear line display portions L1 to L3 along the boundary line of the mounting position of the operation handle 2 are added to each of the number display portions N1 to N3, and the number display portions N1 to N3 You may make it comprise a position display means with the line display parts L1-L3. 6A to 6C show a plate frame 11 on which no switch SW is mounted, a plate frame 11 on which two switches SW are mounted, and a plate frame 11 on which one switch SW is mounted. According to this configuration, since the attachment positions represented by the number display parts N1 to N3 are clarified by the line display parts L1 to L3, it is possible to avoid misreading the number display parts N1 to N3. Further, here, line display portions L1 to L3 are provided on each rib 24 as shown in FIG. 7, and the number display portion is provided at a portion of the vertical frame 13 opposite to the mounting window 15 with respect to the rib 24 in the width direction. N1 to N3 are provided. As described above, when the line display portions L1 to L3 and the number display portions N1 to N3 are arranged side by side in the width direction of the attachment window 15, the number of the line display portions L1 to L3 on the attachment window 15 side is the number. It is easier to align the operation handle 2 when attaching the operation handle 2 than when the display portions N1 to N3 are on the attachment window 15 side.

  In the embodiment described above, on the extended line of the boundary of the mounting position of the operation handle 2 when three switches SW are mounted, and on the extended line of the boundary of the mounting position of the operating handle 2 when two switches SW are mounted. Are provided with the number display portions N1 to N3. However, as shown in FIG. 8, only “3” is provided on the extension of the boundary of the mounting position of the operation handle 2 when three switches SW are mounted. The number display portions N1 and N3 displayed as “” are provided, and a center mark C other than numerals is provided on the extended line of the boundary of the mounting position of the operation handle 2 when two switches SW are mounted.
