The body (7) and the cover (8) are fixed with the mounting screws shown in Fig. 1, 4η. Fig. 6 shows the mounting frame and 3゛θ attached to the cover (8) fixed to the body (7). The attached state is shown.The body (A) corresponds to the quick connection terminal plate (3) of fC terminal block block B.
A wire insertion hole 1481 is drilled in each of the holes.This wire insertion hole! When the conductor +49) of the 481K electric wire is inserted, the display piece (14) is housed in the body f71, so that the connection of the electric wire can be visually observed from the outside. Also, as shown in Figure 5 of the terminal holding plate (I6), press the cover (7) with A and tighten the terminal holding plate (I6) with the top screw α.
It is doubly fixed by No and the cover (8). Figures 8 to 10 show a wireless switch body A with a mounting frame 3η attached, and a decorative frame (5215 #Shi blade (53) for hand operation and transparent native decorative plate I for remote operation). This shows the condition.The lower frame (72 is attached to construction materials to be described later), and the lower frame (72) and the decorative frame sister are used to hold the mounting frame; 371, and the decorative frame f521 is fixed by screwing the frame-shaped middle frame (71) located in the opening of the decorative frame (5) to the mounting frame 3. In other words, the opening of the decorative frame +52j A locking piece (73) protrudes from the periphery of the frame, and the inner frame 171) presses and fixes the decorative frame 1.One decorative play +531 is shown in FIG. 10(a). As shown in FIG. 10(b), the handle (271 is fitted into the fixed spring 40'. The other decorative plate) 1541 is fitted into the opening of the #υ frame (52) as shown in FIG. 10(b).

When attaching the wireless switch body A to the construction surface WK claw by wire, as shown in Figure 11, first fix the wireless switch body A to the mounting frame and wire it, and then attach the mounting frame 3η to the embedded box It is fixed to the construction surface W with screws (74). Next, attach a decorative material Y such as a ribbon to the construction 1frW, and cut the decorative material Y along the mounting frame and the three forces to expose the Wiseless switch body htm. After loosening the screw screw, attach the lower frame σ to the bottom of the mounting frame. At this time, first, attach the screw (74) to the notch near fi in the frame layer.
) and place the bottom frame (72) on top of the bottom frame i79 through the central opening of the bottom frame (72). This is a book that can be attached to the bottom of the first verse.Then, place the mounting frame 3 force on the bottom frame r7, and fit the hole of the mounting frame 3 force into the protrusion of the bottom frame, i. Therefore, even if the decorative material Y is thick, by tightening the screws, the entire decorative material Y in contact with the lower frame ('72) is pressed against the construction surface W side. Decorative frame 152
