And engage the locking claw 11b into the locking hole 8. Locking claw 11
The push button switch 5 locked and fixed by engaging a and 11b with the locking holes 8 and 8, respectively, causes the push button handle 32 to protrude from the window hole 6 of the mounting frame 2. In this manner, since the body is formed to have dimensions that can be attached to the standardized mounting frame 2, the mounting frame 2 and the like can be shared with an embedded wiring device using the mounting frame 2. There is no need to manufacture a new mounting member, which leads to a reduction in manufacturing costs. In addition, there is an advantage that it is not necessary to learn a new technology because the same construction technology as that of the wiring device can be applied during construction. .

The push button switch 5 mounted on the mounting frame 2 is provided with a piano handle 43. The piano handle 43 is as shown in FIG. 3 and FIG. 4, and a locking foot 43a provided on one side edge of the piano handle 43 is locked to a locking projection 70 of the cover 5b, and a fulcrum projection 71 is provided. When the lower surface of the piano handle 43 is in contact with the lower surface of the piano handle 43, the locking leg 43b on the other side edge of the piano handle 43 is inserted into the hole 72 at the other end of the cover 5b so as to be vertically movable and the locking leg 4
The locking portion 3b is locked to the locking edge 72a of the hole 72. When the locking feet 43a and 43b are released, the piano handle 43 can be removed. With the piano handle 43 attached as described above, the push button handle 32 can be pushed and driven by pushing and rotating the piano handle 43. In this state, the semicircular projection 73 on the upper surface of the push button handle 32 contacts the lower surface of the piano handle 43.

Next, the operation of the switch of the present invention will be described with reference to FIGS.

First, the piano handle 43 in the state of FIG. 5 (the piano handle 43 is omitted in FIG. 5).
When the push button handle 32 is pressed down, the push button handle 32 is pressed down against the spring piece 37a.
The reversing handle 31 in which the vicinity of the base of the inner inclined surface of the engaging cam body 38 at the end (the left side in FIG. 5B) is inclined.
5 (b).
When the push button handle 32 is further pressed (FIG. 6 (b)), the engaging projection 34 is pushed down along the inner inclined surface of the engaging cam body 38, and the reversing handle 31 is moved from FIGS. 7 (b) to 9 (b). )
It turns reversely like. By the way, when one engaging cam body 38 of the slide cam 33 slides while engaging with one engaging protrusion 34 of the reversing handle 31, the other engaging cam body 38 is turned before the reversing handle 31 that rotates reversibly becomes horizontal. The length between the pair of engaging cam bodies 38 and the length between the pair of engaging projections 34 are set so as to move and be positioned inside the other engaging projection 34. With the above-described configuration, the hooking projection 34 is turned from FIG. 5 (b) to FIG. 6 (b) to FIG.
As shown in FIG. 8 (b) and FIG. 9 (b), it rotates counterclockwise, and with this rotation, the engaging cam body 38 is opposed to the spring piece 33a by the engaging projection 34 in FIG. 6 (a) → FIG. 7 (a) → FIG. 8 (a) → Slide to the left as shown in FIG.
As shown in (a), the slide cam 33 slides to the left even when the reversing handle 32 is rotated to a position beyond the horizontal position during the reversal of the reversing handle 32 and the other engaging projection 34 rises. The engaging cam body 38 at the other end (right side in FIG. 7B) is located on the left side of the engaging projection 34 on the right side, so that it does not hinder the reversing rotation of the reversing handle 31. . Here, as shown in FIG. 15, if an inner inclined surface is formed inside the engaging projection 34, the inner inclined surface is formed so that the engaging cam body 38 located inside does not interfere when the engaging projection 34 rotates upward. You can escape with. Further, when the reversing handle 31 is rotated in reverse by pushing down the push button handle 32 as described above, the reversing handle 31 is inverted while sliding the slide cam 33 against the spring piece 33a. Reference numeral 33 indicates that the reversing handle 31 can be smoothly reversed by the sliding frictional resistance of the line contact.

When the reversing handle 31 is reversingly rotated as described above, the coil spring 30 reciprocates and swings, the opening / closing body 24 is reversed, and the movable contact 29 is separated from the one fixed contact 25a in contact therewith. , Comes into contact with the other fixed contact 25b.

When the pressing force of the piano handle 43 is released after the reversal, the push button handle 32 is pushed up by the spring piece 37a of the return spring 37 as shown in FIG. 10B, and the piano handle 43 also returns to the original state. become. At the same time, the slide cam 33 slides and returns to the central portion by the spring force of the spring piece 33a, as shown in FIG. If the piano handle 43 is pressed down in this state, the opening / closing body 24 can be inverted by the same operation as described above. After the reversal, if the pressing force of the piano handle 43 is released, the state returns to the state shown in FIG.

In the embodiment shown in FIG. 3, the mounting frame 2 is formed to have three dimensions (three modules) of standardized wiring devices. In the embodiment shown in FIG. One push button switch 5 of one module is mounted on the mounting frame 2 shown, and one piano handle 43 of three modules in size is mounted on the mounting frame 2 of three modules. Although the switch 5 is operated, two push button switches 5 may be mounted on the mounting frame 2 and two piano handles 43 having a size of 1.5 modules may be mounted as shown in FIG. Alternatively, as shown in FIG. 13, three push button switches 5 may be mounted on the mounting frame 2 and three piano handles 43 may be mounted. In this embodiment, as shown in FIG. 13, when the central piano handle 43 is pushed, the piano handles 43 on both sides can be pushed at the same time, and the piano handles 43 on both sides may be pushed alone. As shown in FIG. 14 (c), two piano handles 43 each having a size of 1.5 modules are mounted on one mounting frame 2, and one two-module piano handle 43 is mounted next thereto. Is also good.
In FIGS. 14A, 14B and 14C, K is a decorative frame, which covers the mounting frame 2.
