Reference numeral 77 is an unlock button made of an insulating material for releasing the locked state of the electric wire 1.

Therefore, the switch mechanism portion is the body 55.
By assembling the cover 56 housed inside, and screwing the assembly screw 9 into the screw hole 8 of the frame 1, the assembly of the switch body 7 is completed. Next, a method for attaching the wiring device of the present invention to the construction surface W will be described. First, as shown in FIG. 10, the switch body 7 is fixed to the mounting frame 1 and wiring is performed, and the mounting frame 1 is fixed to the embedded box X or the construction surface W with the screw 2. Next, a decorative material Y such as cloth is attached to the construction surface W, and the decorative material Y is cut along the attachment frame 1 to expose the switch body 7. Then, after loosening the screws 2, the lower frame 24 is attached to the mounting frame 1.
Attach to the bottom surface of. In this case, first, the notch 2a is loosely fitted to the screw 2, the mounting frame 1 is positioned on the lower frame 24 through the opening 25, and then the lower frame 24 is moved to the stereotactic value. Therefore, without removing the mounting frame 1, the lower frame 24
Can be attached to the lower surface of the mounting frame 1.
Then, the mounting frame 1 is placed on the abutting portion 26 of the lower frame 24, the holes 4 of the mounting frame 1 are fitted into the protrusions 26 a of the lower frame 24, and the screws 2 are tightened. Therefore, even when the decorative material Y is thick, by tightening the screw 2, the entire decorative material Y that is in contact with the lower frame 24 is pressed against the construction surface W side.
Next, the plate body 30 is fixed to the mounting frame 1 by the fixing screw 40.
Then, the operation handle 6 is loosely fitted in the window hole 34, and the cylindrical rib 41 of the operation handle 6 is pushed into the recessed chamber 13 of the operation body 10 so that the cylindrical rib 41 of the locking piece 20 of the fixed spring 14 can be inserted. The switch main body 7 is mounted by locking the protrusion 43. Therefore, there is no need to worry about dirt on the operating body 10 due to the decorative material Y such as cloth. And in this case
By fixing the middle frame 37 to the mounting frame 1 and forming the contact portion 39, the operation handle 6 that is connected to the operation body 10 of the switch body 7 is positioned, and when the operation handle 6 is larger than the operation body 10. Also allows the reversal angle to be maintained at a regular position.

By the way, since the display element is fixed to the switch body 7 at a position different from the operating body 10, the display elements 22 and 2 are located above the switch mechanism portion interlocking with the operating body 10.
The fixed position of No. 3 is displaced, and each display element 22, 2
Numeral 3 is electrically insulated from the switch mechanism section, and the display elements 22 and 23 are damaged by an arc when the contacts are opened and closed, and the display elements 22 and 23 themselves do not move like the operating body 10 and therefore do not break. Further, since the display elements 22 and 23 are not provided in the operating body 10 which moves further, it is not necessary to assemble the display elements 22 and 23 and the operating body 10 at the same time, which facilitates the assembly.

FIG. 11 shows a switch circuit formed by using the wiring device of the present invention, in which the power source e is connected to the terminal plate 52 and the load is connected to one fixed terminal plate 60. The other fixed terminal plate 62 is used when forming a three-way switch circuit. In this state, the load L is off,
A current flows through the display element 22 formed of a neon lamp and the light is turned on. The lighting of the display element 22 indicates that the load L is in the off state. At this time, as shown in FIG. 12A, the operation handle 6 is tilted toward the display element 22 side, and the transparent body 44 of the operation handle 6 approaches the display element 22 by the pushing operation of the operation handle 6. The light of the display element 22 is illuminated by the light of the display element 22 to make the light emitting element bright and easy to see from the outside. Next, as shown in FIG. 12 (b), when the operation handle 6 is reversed, the load L is turned on by the power source e.
When the display element 22 is turned off and the display element 22 is turned off, a current flows through the primary winding N ₁ of the power transformer 50, and the secondary output of the current transformer 50 causes the display element 23 to be a light emitting diode that indicates the ON state of the load L Lights up. At this time,
Since the display element 23 on which the operation handle 6 is pressed is turned on, the transparent body 44 approaches the display element 23 to brighten the display, making it easier to see the lighting state from the outside. Then, when the display element 22 is turned on, the transparent body 70 provides a light emission display using green light, and when the display element 23 is turned on, a light emission display is provided with red light, so that the operating state of the switch can be visually recognized by color. FIG. 13 shows the connection in the case of a three-way switch circuit.

In the above embodiment, one switch body 7 is arranged.
