[0017]

(Embodiment 1) FIG. 1 is an exploded perspective view of Embodiment 1 of the present invention. The wiring device in the present embodiment is a so-called tumbler switch (hereinafter, abbreviated as "switch") 40, and a synthetic resin body 40a and a cover 40b are connected by a metal assembly frame as shown in FIGS. The contact opening / closing mechanism is housed inside the body assembled by the assembly, and the boss portion 40 protruding from the cover 40b is provided.
By operating the operation handle 3 which is swingably exposed on the front surface of the contact c, the contact opening / closing mechanism operates to open / close the contact. Since the internal structure of such a switch 40 is conventionally known, illustration and detailed description thereof are omitted.

The body of the switch 40 is formed to have a module size (see JIS C 8304) of a large-sized continuous wiring device standardized by Japanese Industrial Standards (JIS), as shown in FIG. It is mounted on a metal mounting frame 30. The mounting frame 30 is a mounting frame (refer to JIS C 8375) for the large-sized continuous wiring device, and is mounted on an opening surface side of an embedding box 50 buried in a wall by box screws 51, 51, and further combined. A resin plate frame 52 is attached to the front surface by mounting screws 53,53. A decorative plate 54 is attached to the plate frame 52 so as to cover the front surface thereof, and the plate frame 52 and the decorative plate 54 constitute a plate.

On both sides 31a and 31b of the mounting frame 30, an engaging projection 32a is provided for engaging with the groove 1a provided on the assembly frame 1 of the switch 40, and a groove 33 is provided on one side 31b. The thin portion 34 is formed between the opening portion 30a and the opening window 30a. Here, the switch 40 to the mounting frame 30
Is attached to the boss 40c of the switch 40 by the mounting frame 3.
0 so as to be inserted into the opening window 30a.
The engaging projection 32a is engaged with the groove 1a of the assembly frame 1 on one side, and a tool such as a screwdriver is inserted into the groove 33 and pryed to deform the thin portion 34 so as to protrude and deform the other side 31b.
Is engaged with the groove 1a of the assembly frame 1 on the opposite side. The connecting portions 35, 35 connecting the side portions 31a, 31b are engaged with a long hole 35a into which the box screw 51 is inserted, and a clip metal for mounting the mounting frame 30 to a wall material such as a wall panel. And a fixing screw 53 for mounting the plate frame 52.
Is provided with a screw hole 35c into which is screwed. Thus, the box screw 51 is inserted into the long hole 35a of the mounting frame 30 to which the switch 40 is mounted, and the box screw 51 is screwed into the screw hole 50b provided on the tongue piece 50a of the embedding box 50 for mounting. The frame 30 is attached to the front of the embedding box 50.

The plate frame 52 is formed in a rectangular frame shape from a synthetic resin, and has mounting pieces 52a,
A mounting screw 53 is inserted through a screw insertion hole 52b provided in the mounting frame 52a.
Is attached to the front surface of the mounting frame 30 by being screwed into the screw hole 35c provided in the mounting frame 30. The decorative plate 54 has an opening 54 a exposing the boss 40 c of the switch 40, and a locking projection (not shown) protruding near the four corners on the rear surface side is provided on the plate frame 52. It is attached so as to cover the front surface of the plate frame 52 by engaging with the hole 52c.

In this embodiment, as shown in FIG. 2, Braille display portions 20a and 20b are provided on both end surfaces of the operation handle 3 of the switch 40 in the swing direction. Each of the Braille display units 20a and 20b indicates a state of the load operated by the switch 40, that is, “OFF” or “OFF”;
Braille representing "on" or "on" is formed by engraving. Therefore, the state of the switch 40 (the state of the load corresponding to the switch 40) can be known by touching the surface of the operation handle 3 with a finger. For example, if the load is a lighting fixture, forget to turn off the switch 40. After that, the operator can check the state of the switch 40 by touching the Braille display sections 20a and 20b with his / her finger and then press the operation handle 3 with his / her finger as it is to operate the switch 40. Operability can be improved. Also, Braille display unit 2
Since 0a and 20b are formed by engraving, the Braille display portions 20a and 20b are difficult to remove from the operation handle 3, and
In addition, the braille display portions 20a and 20b are separately formed by being integrally formed with the operation handle 3 by engraving.
There is an advantage that the work of attaching to the device becomes unnecessary.

By the way, the contents of the braille display section are not limited to the above-mentioned load state, but the position of the load operated by the switch 40 (for example, "Japanese-style room" or "entrance").
Where lighting equipment is installed as a load),
Alternatively, the type of load (for example, “ventilator” or “lighting”) may be used, and the braille display units 21 and 22 that represent the position of such a load in braille are operated as shown in FIG. 3 or FIG. It may be provided at a substantially central portion of the handle 3.
Thus, the Braille display unit 2 indicating the position of the load and the type of the load
By providing the surfaces 1 and 22 on the surface of the operation handle 3, the usability and operability for visually impaired persons can be further improved.

(Embodiment 2) In this embodiment, as shown in FIG. 5, a handle cover 5a formed of a translucent material such as an acrylic resin into a substantially box shape and removably fitted to the operation handle 3. Braille display portions 23a,
23b is provided.

That is, a name card (not shown) in which information such as the position of the load and the type of the load is written in characters is interposed between the operation handle 3 and the handle cover 5a. Usability and operability can be improved, and at the same time, the Braille display portions 23a and 23b provided on the handle cover 5a improve operability and operability for visually impaired persons.
