It is to be investigated outside through (86). Moreover, the cover piece 87 which protrudes toward the exterior is provided from the front periphery of the light transmission window 86 (end perimeter of the light shield 84).

On the other hand, the pair of bearing projections 23 provided on the cover 20 is a pair of differences in the shape of a strip plate in a form opposite to the light-transmitting window 86 opened on both sides of the protection portion 83 of the lamp cover 80. The miner 27 is provided. Then, the inversion handle 50 is swingable with respect to the cover 20 in a state where the front end portion including the light shielding body 84 of the protective portion 83 is inserted between the pair of light shielding portions 27. Is mounted.

The handle block 2 is comprised of the operation handle 60 formed in the rectangle larger than the front surface of the switch main body 1, and the prism 90 couple | bonded with the back side of the operation handle 60. As shown in FIG. The operation handle 60 includes a main portion 61 formed in a smooth curved shape whose front surface is convex forward, a pair of side walls 62 vertically lowered rearward than both sides in the longitudinal direction of the main portion 61, and a main portion ( Four engaging legs 63 protruding rearward from the four corners of 61 are provided. The cylindrical protrusion 61a which shows the operation position of the operation handle 60 protrudes in the center of the both ends in the longitudinal direction of the front part of the main part 61.

As shown in Figs. 8A to 8F, the prism 90 is a molded product of a transparent synthetic resin, which is arranged to block both sides of the operation handle 60 opposite to the longitudinal direction, so as to light the position indicator 71. It has two display parts 91 which exit outside through the display surface, and the incident surface 92a which is connected to the display part 91 at one end side, and injects the light of the position indicator 71 at the other end side. It engages with the coupling ring 53 provided in the inversion handle 50, and the bow-shaped connection part 93 which connects the two light collecting parts 92, the entrance surface 92a of the two light collecting parts 92, and the like. The engagement ring 94a is provided in the front-end | tip, and it is provided in total in 6 engagement protrusion pieces 94 which protrude rearward from each condensing part 92, and is provided in the longitudinal direction both ends in the inner surface of the display part 91, and is operated. The engaging piece 95 which catches the ring 63a protrudingly provided in the front-end | tip of the engaging leg 63 of the handle 60 is provided. And the operating handle 60 is arrange | positioned between two display parts 91 so that the light condensing part 92 and the connection part 93 may be covered from the front, and it will be at the front-end | tip of the four engaging legs 63 of the operation handle 60. As shown in FIG. The prism 90 is coupled to the back side of the operation handle 60 by engaging the protruding ring 63a with the engaging pieces 95 at both ends of each display portion 91 to form the handle block 2.

The handle block 2 configured as described above has an engagement ring provided at any one end of each of the three engagement protrusions 94 protruding rearward from the two light collecting portions 92 of the prism 90. 94a) is engaged to the front side of the inversion handle 50 by engaging the engagement ring 53 of the inversion handle 50. In other words, the plate frame 101 is provided with three sets of device holes 102, and at most three switch bodies 1 can be attached side by side in the short width direction (see Figs. 2A to 2D). The switch main body 1 attached to the hole 102 is connected to the switch main body 1 attached to the device holes 102 at both ends by using the engaging ring 94a of the center engaging projection piece 94. For example, by using the engagement ring 94a of the engagement projection piece 94 at either end, the device position of the handle block 2 is shifted away from the short width direction of the switch main body 1 (refer FIG. 1). . With such a configuration, it is not necessary to prepare three types of handle blocks 2 according to the device position of the switch body 1 with respect to the plate rim 101, and it is common regardless of the device position of the switch body 1. Since the handle block 2 can be used, there exists an advantage that a workability improves. Here, in the handle block 2 attached to the switch main body 1 located in the both ends of the plate edge 101, only the engagement ring 94a (engagement projection piece 94) of one end side is inverted handle ( Used for engagement with 50), the engagement hook 94a (the engagement protrusion 94) on the other end side is pushed out of the opening 103 of the plate rim 101, so that it is pushed out It is necessary to provide the receiving means for receiving the fitting ring 94a (the locking projection 94) on the plate rim 101. Therefore, in the present embodiment, the engagement ring pushed out from the opening 103 of the plate frame 101 is combined with a pair of holes 106 provided in the plate frame 101 to attach the metal parts. Each of the holes 94a (engaging projections 94) can be inserted into the holes 106 and received. In addition, an increase in the manufacturing cost of the plate frame 101 can be suppressed as compared with the case of separately providing a receiving means.

Thus, the operation of the present embodiment constituted as described above will be briefly explained. When the right end of the operation handle 60 (the handle block 2) is located behind the left end (below the figure) as shown in FIG. The movable contact 42b is in contact with the fixed contact 41b. In this state, the reverse spring 44 is in a state in which the intermediate portion is bent to the left side with respect to both ends, so that the movable contact 42b is pressed against the fixed contact 41b by the reverse spring 44 to apply a contact pressure. On the other hand, when the left end of the operation handle 60 is pushed backward from this state, since the reversal handle 50 swings in the counterclockwise direction in the drawing, the reversal spring 44 is in a state in which the intermediate part is bent to the right with respect to both ends. At this time, the opening / closing element 43 is rotated in the clockwise direction in the drawing to separate the movable contact 42b from the fixed contact 41b, and simultaneously contact the movable contact 42a with the fixed contact 41a. In the state where the movable contact 42a is in contact with the fixed contact 41a, the left end of the operation handle 60 is located behind the right end. That is, whenever an end portion located forward of the operation handle 60 is pushed backward, the contact device 40 has the fixed contact 41a, the movable contact 42a, the fixed contact 41b and the movable contact ( The contacting and work separation of 42b) are alternatively converted.

By the way, in the state in which the switch main body 1 and the handle block 2 were couple | bonded, on the optical path between the position indicator 71 and the light condensing part 92 of the prism 90, the bearing of the cover 20 is carried out. A pair of light shielding portions 27 arranged between the projection pieces 23 are disposed at opposing positions with the swinging points of the operation handle 60 (the handle block 2) interposed therebetween, and the lamp cover ( The light shielding body 84 provided in 80 is arrange | positioned in the position which opposes these pair of light shielding parts 27 and the switch main body 1 in the front-back direction (up-down direction in FIG. 3). Therefore, both end portions of the operation handle 60 are moved from the front to the rear or the rear to the front, respectively, in response to the pressing operation, and the swinging point of the operation handle 60 (point projection of the inversion handle 50) at the end moved back. (51) end position (cover piece 87) of the light shielding body 84 overlaps (or abuts, is the same below) the one light shielding part 27 provided in the said end side, and a position indicator light is shown. An optical path between the light source 71 and the light collecting portion 92 of the prism 90 is shielded. In addition, in the end part which moved forward, the edge part of the light shielding body 84 does not overlap with the other light shielding part 27 provided in the said end side with respect to the rocking | fluctuation point of the operation handle 60, and a position indicator light The light path between the 71 and the light collecting portion 92 of the prism 90 is not blocked. For example, in the state where the left end of the operation handle 60 is in the front and the right end is in the rear, as shown in FIG. 3, the right end of the light shielding body 84 (the lid piece 87) is attached to the right light blocking part 27. Since the light transmission window 86 is almost blocked by overlapping, the light path between the right light collecting portion 92 and the position indicator 71 is shielded by the light blocking portion 27 and the light shielding body 84 so that the right display portion 91 The light of the position indicator 71 is not emitted to the outside from the display surface. However, the left light-shielding portion 27 does not overlap the left end of the light-shielding body 84, and the light-transmitting window 86 is not blocked, so the light path between the left light-collecting portion 92 and the position indicator 71 is shielded. Light of the position indicator 71 is radiated to the outside from the display surface of the display part 91 on the left side without being shielded by the 27 and the light shield 84. In addition, although detailed description is abbreviate | omitted, in FIG. 3, the position indication is shown from only the right display part 91 which is front even in the state which the right end of the operation handle 60 is in front, and the left end is rearward, contrary to the above description. It is apparent that the light of the lamp 71 is emitted and the light of the position indicator 71 is not emitted from the left display portion 91 at the rear.

As described above, in the present embodiment, since the light of the position indicator 71 is emitted only from the display surface of the display portion 91 provided at the end of the operation handle 60 of the portion to be operated next, the operation handle The display position of (60) can be completely aligned with the operation direction, and the operability can be improved as compared with the conventional example. In addition, even when the light shielding portion 27 is not provided between the bearing protrusions 23 of the cover 20 as shown in FIG. 9, the light of the position indicator 71 is displayed in two display portions 91. The display position and the operation direction of the operation handle 60 are simultaneously emitted from two display portions 91 provided at both ends of the operation handle 60 and exited from the display surface of the control panel 60 at the same time. By matching, the operability can be improved.

In addition, in this embodiment, the attachment part (locking piece 95) which attaches the operation handle 60 to the front side is provided, and the engaging part (engaging ring 94a) which engages with the inversion handle 50 on the back side. Is provided, and since the prism 90 can be coupled to the inversion handle 50 after the operation handle 60 is attached to the prism 90, the assembling operation becomes easy. Moreover, the position indicator 71 is exposed and installed in the front side of the inversion handle 50, and the light shield 84 of the lamp cover 80 is formed in the umbrella shape which covers the position indicator 71 from the front. Therefore, by arranging the position indicator 71 in the vicinity of the prism 90, the light of the position indicator 71 can be efficiently collected in the light collecting portion 92, and the brightness of the display portion 91 is also improved. have. Here, in the present embodiment, since the two display portions 91 are formed in substantially the same dimensions as the ends of the operation handles 60, the display portions 91 are easy to confirm. In addition, when the diffusion material is mixed with the transparent synthetic resin material to have diffusivity in the display portion 91 or the entire prism 90 including the display portion 91, the emission range of light is widened to confirm the display portion 91. Easier

In the present embodiment, the lamp cover 80 is made of a synthetic resin molded article. However, when the entire lamp cover 80 or the protection portion 83 or the light shield 84 is formed of a metallic material having a gloss, the position indicator ( The light of 71 may be reflected by the light shield 84 or the inner surface of the protection unit 83 and efficiently collected by the light collecting unit 92, thereby improving the brightness of the display unit 91. However, when the whole or part of the lamp cover 80 is made of metal, it is necessary to insulate the position indicator 71, the resistance element 72, etc., so that the lamp cover 80 made of a synthetic resin molding having insulation A reflective sheet formed by adhering a sheet material that reflects the light of the position indicator 71 to the inner surface of the light shield 84 or the protection portion 83 of the < RTI ID = 0.0 >), or < / RTI > By providing a reflective layer formed by coating a dye or a metallic material), the brightness of the display portion 91 can be improved without insulating the position indicator 71 or the like.

In addition, in this embodiment, although the case where three switch main bodies 1 are attached to the plate edge 101 was illustrated, as shown to FIG. 10A and FIG. 10B, two switch main bodies are provided at both ends of the plate edge 101. FIG. In the case of attaching (1) or in the case of attaching one switch main body 1 to the center of the plate rim 101 as shown in Figs. 11A and 11B, the short main direction of the switch main body 1 What is necessary is just to combine with the handle block 2 which consists of the operation handle 60 and the prism 90 which enlarged the width dimension 1.5 times and 3 times, respectively.

(Example 2)

As shown in FIG. 12, the basic structure of this embodiment is common with Example 1, the same code | symbol is attached | subjected to a common component, and illustration and description are abbreviate | omitted suitably. In addition, even if the shape is slightly different, the same reference numerals are given if the functions are common.

In the first embodiment, the lamp cover 80 and the light shield 84 are integrally formed, but in the present embodiment, the lamp cover 80 and the light shield 84 are formed separately, and the light shield 84 is covered. The rotation is made of material according to the swinging direction of (20).

The lamp cover 80 includes a main part 81 having a center opening of an insertion passage hole 81a through which the tube part 54 is inserted into a rectangular box shape having a rear surface open as shown in FIGS. 13A to 13D, and a main part. A pair of protrusions 82 protrude forward from both ends of the 81 to accommodate the resistance element 72 therein, and the tubular portion 54 is inserted through the insertion hole 81a of the main portion 81. It is fixed to the inversion handle 50 by connecting the locking ring 85 which protruded from the longitudinal direction both sides of the main part 81 to the locking parts 56 provided in the both sides of the inversion handle 50 in the state (refer FIG. 12). .

As shown in Figs. 14 and 15A to 15C, the light shield 84 has a semi-cylindrical light shield 84a whose cross-sectional shape is curved along the tube wall of the position indicator 71, and the light shield 84a. The triangular support part 84b which protrudes outward along the axial direction from the both ends of the axial direction of () is integrally formed as a synthetic resin molding. Around both ends in the axial direction of the light shielding portion 84a, a rectangular recess 84c and a lid piece 84d protruding outward from the periphery of the recess 84c are provided, respectively. Moreover, the support part 84b has a cylindrical hole whose center axis coincides with the axial direction of the light shielding part 84a, and the bearing hole 84e which a part was opened along the axial direction, and the front-back direction (up and down in FIG. 14) by the square in plan view. Direction 84f which penetrated in the (direction) is provided, respectively.

On the other hand, as shown in FIG. 16, the pair of bearing projections 23 of the cover 20 has a cylindrical shaft projection 23a at a portion closer to the tip side than the bearing recesses 24 on opposite surfaces. Are projected respectively. Thus, by filling the bearing holes 84e with the two shaft protrusions 23a of the bearing protrusions 23, respectively, the light shielding body 84 has the shaft protrusion 23a as a point, and is inverted with respect to the cover 20. It becomes rotatable in the same direction as the swinging direction of 50. Moreover, as shown in FIG. 17, as for the inversion handle 50, the fixing rib 57 which protrudes forward (upper in FIG. 17) rather than the front periphery of a pair of point protrusion 51 is provided, respectively. . That is, the light shielding body 84 is connected with the inversion handle 50 by inserting the front end of the fixed rib 57 into the connection hole 84f provided in the support part 84b of the light shielding body 84.

Thus, the operation of the present embodiment configured as described above will be briefly described. For example, as shown in FIG. 12, in the state where the left end of the operation handle 60 is in the front (upper in FIG. 12) and the right end is in the rear (lower in FIG. 12), the right light shielding portion 27 ), The right end (cover piece 84d) of the light shielding body 84 overlaps, so that an optical path between the light collecting portion 92 on the right side and the position indicator 71 is formed. 84, the light of the position indicator 71 is not emitted from the display surface of the display part 91 on the right side to the outside. However, the left light-shielding portion 27 does not overlap the left end of the light-shielding body 84, so the light path between the light-collecting portion 92 on the left side and the position indicator 71 is provided with the light-shielding portion 27 and the light-shielding body ( The light of the position indicator 71 is emitted to the outside from the display surface of the left display portion 91 without being shielded by the light 84. Similarly, in FIG. 12, the light of the position indicator 71 is emitted from only the display portion 91 on the right side, which is in front even when the right end of the operation handle 60 is in the front and the left end is in the rear, The light of the position indicator 71 is not emitted from the display portion 91 on the left side at the rear side.

Here, in Embodiment 1, since the light shield 84 is integrally formed with the lamp cover 80, the rotation point of the light shield 84 is the swing point of the operation handle 60 (the point projection of the inversion handle 50) 51)), in the present embodiment, the rotation point of the light shielding body 84 becomes the shaft protrusion 23a provided on the bearing protrusion 23 of the cover 20, and furthermore, Since the fixed rib 57 is formed to be slightly thinner than the inner diameter of the connection hole 84f, the rotation angle of the light shield 84 becomes larger than the swing angle of the inversion handle 50. As a result, as compared with the case where the light shield 84 does not rotate with respect to the inversion handle 50 as in the first embodiment, the light shield 84 and the light shield portion 27 do not overlap between them in a state where they do not overlap. Since the gap (light path) becomes large, the brightness of the display portion 91 can be increased. In addition, since the amount of overlap between the light shield 84 and the light shield 27 is increased, light leakage to the display portion 91 can be suppressed.

(Example 3)

This embodiment is characterized by the handle block 2, and other configurations are common to the second embodiment as shown in Figs. Therefore, the same code | symbol is attached | subjected to the component common to Example 2, and illustration and description are abbreviate | omitted suitably. In addition, even if the shape is slightly different, the same reference numerals are given if the functions are common.

The handle block 2 according to the present embodiment has an operation handle 60 formed in a flat box shape which is open in a rectangular shape in the rear view (downward in FIG. 18), the display portion 91 and the light collecting portion 92. It consists of two prisms (90, 90) having a. The two prisms 90 are the same, and as shown in FIG. 20, the display portion 91 and the light collecting portion 92 are integrally formed of a transparent synthetic resin material. The light collecting portion 92 is fixed to the inner bottom surface of the operation handle 60 by a fixing piece 92c protruding from one end in a flat rectangular shape. That is, a pair of holes penetrate the fixing piece 92c in the thickness direction, and each of the protrusions 64 protruding from the inner bottom surface of the operation handle 60 is inserted into the hole to caulk the tip end. ), The fixing piece 92c is fixed to the operation handle 60 (see FIG. 21). At this time, the inner end surface (incidence surface) of the light collecting portion 92 opposes the gap (light path) between the light blocking body 84 and the light blocking portion 27 (see FIG. 19). Further, at the end of the light collecting portion 92 on the side where the fixing piece 92c protrudes, an inclined surface 92b is formed on the back side, and the display portion 91 is provided on the front surface side that faces the inclined surface 92b. The display portion 91 is formed in a belt shape projecting in an elliptical shape in plan view, and the cross-sectional shape of the tip portion thereof is formed in an arc shape. The elliptical long hole 67 penetrates in the front-back direction at both ends of the operation handle 60, and when the fixing piece 92a is fixed to the operation handle 60, the display part 91 has the long hole 67 The front end portion of the display portion 91 protrudes from the front surface of the manipulation handle 60 by being inserted into the through portion (see FIG. 19).

As shown in FIG. 21, four engagement protrusions 68 provided with the engaging ring 68a at the front end are engaged with the engaging ring 53 of the inversion handle 50 on the inner bottom surface of the operation handle 60. As shown in FIG. The prism 90 is arrange | positioned between the two engagement protrusion pieces 68 which protrude in the back and become neighbors in a short width direction, respectively.

Thus, as in the second embodiment, the light of the position indicator 71 emerging from the gap between the light shielding body 84 and the light shielding portion 27 is incident on the light collecting portion 92 of the prism 90 from the incident surface. Since the light refracted by the inclined surface 92b is emitted only to the front of the operation handle 60 through the display portion 91, the display portion 91 viewed from the front as compared to the first and second embodiments which are emitted not only to the front but also to the side. ) Has the advantage of improving the brightness. In addition, in this embodiment, although the engaging projection piece 68 for coupling the handle block 2 to the inversion handle 50 is provided in the operation handle 60, the prism (like Example 1 or Example 2) is provided. Providing the engaging projection pieces at 90 and 90 has the advantage that the degree of freedom of the shape of the prism 90 is improved because a space for avoiding the engaging projection 68 provided in the operation handle 60 is unnecessary. In addition, although the projection piece 94 is provided in the prism 90 in the said embodiment, the projection piece 94 may be provided in the operation handle 60. As shown in FIG.

According to the present invention, when the power supply from the power supply to the load is stopped, the light emitting source emits light and the light is guided to the light collecting portion and is emitted from the display surface of the two display portions (or the first and second display portions) to the outside. Therefore, the display is simultaneously performed on the two display units (or the first and second display units) provided at both ends of the swinging operation handles, so that even when a twin throw contact device is used, the display position of the operation handles coincides with the operation direction. This has the effect of being improved.
