の合図に利用できるというものである。[Prior Art] Conventionally, as a switch device equipped with a plurality of independently operated switches for driving different functions, there is, for example, one shown in Japanese Utility Model Application Publication No. 54-175574. By providing the operation buttons in different positions for each purpose, this product allows multiple operation buttons to be used for different purposes without confusing the operation, and also hides the existence of a single operation button from anyone other than a specific person. This operation button can be used for internal signals.

However, in this case, the hidden operation button is operated in a direction perpendicular to the first operation button, and when the hidden operation button is pressed, the side surface of the cover plate that covers this operation button gets in the way of operation. The drawback was that it was difficult to press the switch and it was difficult to obtain the predetermined operating stroke necessary to close the switch.

Therefore, this invention provides at least two through holes on the top surface of the main body case that lead to the inner surface of the main body case, and inserts the operation rods of the independent switch operation buttons into each through hole, so that the individual switch operation buttons stored inside the main body case can be connected to each other. One of the switch operation buttons is exposed from an opening on the top of a decorative case that is larger in appearance than the main case, and is attached to the top side of the main case, and the operating direction is controlled. It is arranged so that it can be pressed from the top surface to the bottom surface of the main body case, and the other one of the switch operation buttons
One is a position that extends from the top surface to the side surface of the main body case and is hidden by the decorative case when viewed from above, and is arranged so that the operating direction is from the bottom surface of the main body case to the top surface. By exposing the hidden operation button from the joint, the operability of the hidden operation button is greatly improved, and a stable operation stroke can be obtained at any time.
以下この考案の実施例を図面により説明する。 Examples of this invention will be described below with reference to the drawings.
第１図において、１はABS樹脂製の本体ケー

する。 Reference numeral 26 denotes a decorative case that is attached to the top surface of the main body case 1, which has a larger external shape than the main case 1, and has an opening 27 through which the first switch operation button 13 is exposed on a surface corresponding to the above-mentioned top surface. It can be pressed directly from the front. Further, a notch 28 is provided in a part of the side surface of the decorative case 26, and the second switch operation button 15 is arranged so as to be hidden by the decorative case 26 when viewed from above when the decorative case 26 is attached to the main body case 1. And then the third
As shown in the figure, the tip of the second switch operation button 15 is exposed from the joint S between the two, allowing it to see-saw toward the notch 28 side. This operation button 15
The thumb O is decorated with the case 26 as shown in Fig. 3.
If you place your index finger H on the operation button 15 and then pinch it, the operation button 15 will be pressed.
makes a see-saw motion by the support shaft 24, and the operating rod 16 at the tip further penetrates and presses the switch B to close it.

る。 In this way, the first switch operation button 13 is pressed from the front side of the decorative case 26, while the second switch operation button 15 is operated by pulling it back toward you from the rear side of the decorative case 26.
The operating directions for both are completely opposite, so there is no mistake in using it, and the second switch operation button 15 is exposed in a hidden part from the front, so it can only be seen by those in the inner circle, making it difficult to identify who is operating it. This can be determined by the behavior of different functions such as tone.

わらず構造が複雑になることもない。 In particular, when operating the second operation button 15, place the thumb O on the top surface of the decorative case 26 that covers the operation button 15, and use the thumb O as a fulcrum to pinch and operate the index finger placed on the operation button 15. operation button 15 in a hidden position.
can be easily operated, the predetermined operation stroke can be easily obtained, and the existing decorative case 26 can be used as an auxiliary means when operating the operation button 15, so even though it has become easier to operate. The structure does not become complicated.
このようなスイツチ操作釦１３，１５は２つだ
けではなく、操作される機能数に応じて、例えば

除するように形成されている。 Note that the cutout 28 of the decorative case 26 for the pull-back stroke of the second switch operation button 15 is
By setting the width to 6 to 8 mm, the operating button 15 can be inserted into the opening, but the finger cannot be inserted into the opening, thereby limiting the operating stroke and preventing unnecessary deformation of the movable contact plate 10. 29 is a discharge hole that emits sound from the built-in speaker 2, and the decorative case 26
Since the sound emission performance deteriorates when the decorative case 26 is covered with a sound emission hole, it is necessary to provide a sound emission hole in the decorative case 26 as well. However, if this type of sound emitting hole is opened too wide, rain will easily enter when used outdoors, but in this case, a raised part 30 is provided protrudingly as shown in Fig. 2, and the raised part 30 is horizontally Sound emission hole 31 to open
In addition, on the main body case 1 side, a vertical surrounding rib 32 is provided protruding from the periphery of the sound emission hole 29 of the speaker 2, so that even if rain enters through the sound emission hole 31 of the decorative case 26, this The enclosing rib 32 is formed to prevent entry into the speaker 2 and exclude it from the case.

It also surrounds the mounting surface P of the second switch operation button 15 and the terminal window 7. In the drawing, 33 is a polyethylene waterproof sheet that is clamped between the sound emission hole 29 and the speaker 2, and 34 is a
This is a gasket attached to the bottom surface of the main body case 1 to absorb external force when the main body case 1 is attached to a wall.
Made of NBR and silicone rubber.

By pulling up the operation button 13 to the position indicated by the broken line, it will be exposed, and after the screw is fixed, it will be covered and hidden by returning the operation button 13 to its original position. Since only the upper screw hole 35 can be seen,
Especially not prone to theft.

Two through holes 11, 12 are provided, each through hole 11, 1
2, the operation rods 14 and 16 of the independent switch operation buttons 13 and 15 are inserted to open and close the individual switches A and B housed inside the main body case, One is
The decorative case 26, which is attached to the upper surface of the main body case 1 and has a larger external shape than the main case 1, is exposed through the upper opening 27, and the operation direction is pressed from the upper surface to the lower surface of the main body case 1. The other one of the switch operation buttons extends from the top surface of the main body case 1 to the side surface, is in a position hidden by the decorative case 26 when viewed from above, and has its operation direction directed toward the main body. Since the case 1 is exposed from the joint between the main case 1 and the decorative case 26 from the bottom surface to the top surface, it is suitable for a switch device having hidden operation buttons with different operation directions so that the user can operate them without confusion. Therefore, with an extremely simple structure, the decorative case is used as an auxiliary means during operation to improve the operability of the hidden operation button and to obtain a reliable operation stroke.
