In conventional push button switches, the method of converting the switch to reverse operation has problems such as a deep embedding depth and poor workability.

The present invention has been made in view of the above-mentioned problems and disadvantages, and its objectives are to provide easy operation with annotouch operation, a good appearance, and a thin design with opening/closing performance similar to that of conventional wave switches. It is to provide a piano handle type switch that can be on the same level as the piano.

[! ! Means for Solving the Problem] The piano handle type switch of the present invention includes an opening/closing body 24 that is rotatably supported within a body and opens and closes a contact portion, and a head that is exposed from the surface of the body. A push button handle 32 is mounted inside the container so as to be movable in a direction perpendicular to the plane, and an opening/closing body 24 is operated in conjunction with the push of the push button S handle 32.

A push button switch 5 includes a return means for biasing the push button handle 32 in the forward exposure direction, and a push button handle 5 whose one side is rotatably supported on the outside of the push button switch 5 and whose back surface is pivoted.
In the anno-handle type switch, the reversing means is connected to the opening/closing body 24 via a fill spring 30 to control the direction of rotation of the opening/closing body 24. It is pivoted to the instrument body so that it can freely see-saw and the direction of the rotation axis is parallel to the direction of the rotation axis of the piano handle 43, and engaging protrusions 34 are formed on the surfaces of the push button handles 32 at both ends. Among the reversing handle 31 and the engaging cam bodies 38 formed at both ends in conjunction with the pushing of the push button handle 5, the reversing handle 31 corresponds to one of the engaging protrusions 34 that approaches the push button handle 32 due to the inclination of the reversing handle 31. A slide cam 33 made of synthetic resin that applies a reversing rotational force to the reversing handle 31 by sliding on the back surface of the push button handle 32 in a direction perpendicular to the pushing direction while pressing and engaging the engaging protrusion 34 with an engaging cam body 38. , and a return elastic body that is integrally molded with the slide cam 33 and whose free end is connected to the push button handle 32@ to provide an elastic force in the counter-sliding direction with respect to the sliding of the slide cam 33. 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 rotates in reverse until the reversing handle 31 becomes horizontal. The length of the pair of engaging cam bodies 38 and the length between the pair of engaging protrusions 34 are set so that the engaging cam body 38 moves and is located inside the other engaging protrusion 34, and this By adopting such a configuration, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[Function] According to the present invention, by pushing down the piano handle 43, the push button handle 32 is pushed down, and the push button handle 32 is pushed down.

The slide cam 33 is slid by one engaging cam body 38 engaging with the rotating engaging protrusion 34 , and in this case, one engaging cam body 38 of the slide cam 33 engages with one engaging protrusion 34 of the reversing handle 31 . The pair of engaging cam bodies 38 are arranged so that the other engaging cam body 38 moves and is positioned inside the other engaging protrusion 34 before the reversing handle 31, which rotates without sliding while being engaged with the inverting handle 31, becomes horizontal. By setting the length between the two engagement protrusions 34 and the length between the pair of engagement protrusions 34, even if the reversing handle 31 rotates and the other engagement protrusion 34 rises, the slide cam 3
3, and the reversing rotation of the reversing handle 31 is no longer hindered.

Instead of the fulcrum projection 71 provided on the lower surface of the piano handle 43, a fulcrum projection 71 may be provided on the lower surface of the piano handle 43.

Next, the operation of the via seven handle type switch of the present invention will be explained based on FIGS. 5 to 10.

First, in the state shown in FIG.
When the piano handle 43 is omitted in the figure) is pushed down, the push button handle 32 is pushed down against the spring piece 37a, and as the push button handle 32 is pushed down, the slide cam 33 is lowered and one of the slide cams 33 (the fifth The vicinity of the base of the inner inclined surface of the engaging cam body 38 at the end (left side in FIG. 5(b)) hits the engaging protrusion 34 on the upper side (left side in FIG. 5(b)) of the inverted handle 31 ( The state shown in Fig. 6(b)!! and the push button handle 32
When pressed, the engaging protrusion 34 is pushed down along the inner slope of the engaging cam body 38, and the reversing handle 31 moves as shown in FIG.
b) to reverse rotation as shown in FIG. 9(b).

By the way, when one of the engaging cam bodies 38 of the slide cam 33 slides while engaging with one of the engaging protrusions 34 of the reversing handle 31, the other engaging cam body 38 becomes horizontal before the reversing handle 31 that rotates in reverse becomes horizontal. Move to the other engaging protrusion 3
The length between the pair of engaging cam bodies 38 and the length between the pair of engaging protrusions 34 are set such that the length between the pair of engaging cam bodies 38 and the length between the pair of engaging protrusions 34 are located on the inside of the cam body 4. With the above configuration, as the reversing handle 31 is reversed by pressing down the push button handle 32, the engaging protrusion 34 changes as shown in FIG. 5(b), FIG. 6(b)→FIG. 7(b)→FIG. 8. (
b)→It rotates counterclockwise as shown in FIG. 9(b), and with this rotation, the engaging cam body 38 is moved by the engaging protrusion 34 against the spring piece 33a as shown in FIG. 5(a). Slide to the left as shown in Figure 6 (, ) → Figure 7 (, ) → Figure 8 (a) → Figure 9 (a), and flip as shown in Figure 8 (b) / ) Handle 3
Even if the reversing knob 1 handle 32 rotates beyond the horizontal position during the reversal of the second end 1 (17 In Figure (b), the right engaging cam body 38 is located to the left of the right engaging protrusion 34 so that it does not interfere with the reverse rotation of the reversing nozzle 31.

Here, if an inwardly inclined surface is formed on the inside of the engaging protrusion 34 as shown in FIG. 15, the inwardly inclined surface can be formed so that the engaging cam body 38 located on the inner side does not interfere when the engaging protrusion 34 rotates upwardly. You can get away with it. In addition, when the reversing handle 31 is rotated in the reverse direction by pressing down the push button handle 32 as described above, the reversing handle 31 is rotated by reversing the reversing handle 31 while sliding the slide cam 33 against the spring piece 33a. The slide cam 33 is capable of smoothly rotating the reversing nozzle 31 in reverse without receiving sliding frictional resistance.

When the reversing handle 31 is reversely rotated as described above, the coil spring 30 is reversely swung, the opening/closing body 24 is reversed, and one of the fixed contacts 25a with which the movable contact 29 is in contact
It separates from the contact point 25b and contacts the other fixed contact point 25b.

After this reversal, when the pressing force of the piano handle 43 is released, the spring piece 37 of the return spring 37 is
At step a, the push button handle 32 is pushed up, and the piano handle 43 also returns to its original state. At the same time, the slide cover 33 also slides back to the central position by the spring force of the spring piece 33a, as shown in No. 10l6). In this state, via 7
By pushing down the handle 43, the opening/closing body 24 can be reversed by the same operation as described above. After this reversal, if the downward force on the piano handle 43 is released, the state shown in FIG. 5 will be restored.

By the way, in the embodiment shown in FIG. 3, the mounting frame 2 is formed to a size (3 monoyl) for three standardized wiring devices, and in the embodiment shown in FIG. A 1-monoyl 1@ push button switch 5 is attached to the mounting frame 2 shown, and a 3-monoyl piano handle 43 is attached to the 3-module mounting frame 2, and the large piano handle 43 allows one push button to be pressed. The switch 5 is to be operated, and as shown in FIG. 12, the 2 @ push button switch 5 is attached to the mounting frame 2, and two piano handles 43 each having the size of a 1.5 monologue are attached. Alternatively, as shown in FIG. 13, three @ push button switches 5 may be attached to the mounting frame 2 and three vias 7 handles 43 may be attached. Furthermore, in this embodiment, as shown in FIG. 13, when the central piano handle 43 is pushed, the anno handles 43 on both sides can be pushed simultaneously, and the anno handles 43 on both sides can be pushed independently. Good too. In addition, as shown in FIG. 14(c), two piano handles 43 each having a size of 1.5 modules are attached to one mounting frame 2, and one
A two-monoyl piano handle 43 may be attached. In addition, in FIG. 14 (-Hb) (c), K is a decorative frame that covers the mounting frame 2.

[Effects of the Invention 1] As described above, the reversing means of the present invention is coupled to the opening/closing body via a coil spring so as to be freely movable in the rotating direction of the opening/closing body, and the direction of the rotation axis is via a via. 7) A reversible handle that is pivoted on the body so as to be parallel to the direction of the rotation axis of the handle and has engaging protrusions formed on the push button handle side surfaces of both ends, and the push button is interlocked with the push of the handle. Among the engaging cam bodies formed at both ends, the engaging cam body corresponding to one of the engaging protrusions that approaches the push button handle due to the inclination of the above-mentioned reversing handle presses and engages the engaging protrusion while pressing in the pushing direction. A slide cam made of synthetic resin that slides on the back surface of the push button handle in the orthogonal direction and applies a reversal rotation force to the reversal/handle, and is integrally molded with this slide cam, and the free end is connected to the handle side of the push button. It is composed of a return elastic body that applies a resilient force in the counter-sliding direction to the sliding of the slide cam, and one engaging cam body of the slide cam slides while engaging one engaging protrusion of the reversing handle. The length between the pair of hooking cam bodies and the distance between the pair of hooking protrusions are determined so that the other hooking cam body moves and is positioned inside the other hooking protrusion before the reversing handle that rotates in reverse when moving is turned into a water bottle. Since the length is set, the pushbutton handle is pushed down by the push-down operation of the piano handle, and the push-down motion can be smoothly converted to the inversion rotational motion of the inversion handle via the slide cam, and the push-down motion can be reversed. The mechanism that converts into rotational motion has a simple configuration and is thin.As a result, it is easy to operate with via/touch operations, has a good appearance, and has the same opening/closing performance as a conventional wave switch. It is something that can be done.
