Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a changeover switch mounting structure that easily displays the channel of the changeover switch.

(B) Prior Art In the conventional channel display etc. of a changeover switch, for example, numbers for channel display are arranged on the panel surface to which the changeover switch is attached or around the changeover switch itself.

However, this type of changeover switch has the problem that many numbers are visible to the operator with the same brightness, making it difficult to immediately discern the number indicated by the changeover switch, which may lead to erroneous recognition.

On the other hand, switches with a structure that hides numbers other than those indicated have also been proposed, but such switches have the disadvantage of being complex and expensive.

(c) Purpose The purpose of this invention is to provide a switch mounting structure that allows an operator to easily recognize channel indications, etc., even though it has a relatively simple configuration.

(d) Configuration The changeover switch mounting structure according to this invention includes a knob having a translucent flange,
The display includes a display provided around the flange portion and a panel located below the flange portion, and the panel has a color in a portion corresponding to the indicated position of the switch that has a brightness difference with respect to the color of the display. In addition to being set to a certain color, the color of the area other than the indicated position is set to approximately the same brightness as the color of the display, and the display located at a position other than the indicated position on the panel is visually recognized by being confused with the color of the panel. The display at the indicated position on the panel is constructed so that it stands out in the color of the indicated position.

(E) Embodiment FIG. 1 is an explanatory diagram schematically showing the structure of an embodiment of the changeover switch mounting structure according to this invention.

In the figure, 10 is a changeover switch, and this changeover switch 10 includes a truncated conical knob 11, a flange portion 12 provided at the bottom of the knob 11, a switch body 14 equipped with a multi-contact switching mechanism, and a switch body 14. It consists of a shaft 15 connecting a knob 11. The flange portion 12 is made of transparent synthetic resin, and has, for example, “1” on its back side.
Displays 13 drawn in black such as ``5'' are arranged in an arc shape at equal intervals.

Reference numeral 20 denotes a panel formed from a transparent synthetic resin plate, the back surface 21 of which is colored black.
The indicating portion 22, which is the panel portion corresponding to the indicated position of the changeover switch, and the function display 23 of the changeover switch are colored transparent white. Such coloring is performed, for example, by attaching synthetic resin sheets of predetermined patterns of respective colors to the flange portion 12 or panel 20.

30 is a board to which the switch body 14 and a lamp 31 that is turned on when the surroundings are dark are connected. The lamp 31 is connected to the instruction section 22 and the function display 2.
It is installed in a position opposite to 3.

In the changeover switch mounting structure having the above-described configuration, when the knob 11 is rotated to bring the appropriate display 13 to the position of the instruction section 22,
Since the indicator 22 is white, the black display 13 ("1" in FIG. 1) stands out above the indicator 22 and is easily read. On the other hand, the display 13 located outside the position of the instruction section 22
Since the panel 22 is black ("2" to "5" in the figure), it looks like a protective color, making it difficult to visually recognize it.

Further, when the surroundings are dark, the lamp 31 is turned on. Since the instruction section 22 and the function display 23 are colored transparent white, the light from the lamp 31 passes through the colored section, the panel 20, and the flange section 12, and is irradiated to the outside. Therefore, even at night, the indicated display 13 and function display 2
3 stands out, while display 13, which is not designated, is hardly noticeable.

In the above-described embodiment, the lamp 31 was provided in consideration of display when the surroundings are dark, and the panel 20 was accordingly formed of a transparent material. However, when such considerations are not required, lamp 31 is not required and panel 20 does not need to be formed from a transparent material. However, in this case, the coloring of the panel 20 is of course applied to the surface.

In addition, in the description of the embodiment, the display 13 and the back surface 21 of the panel are black, the instruction section 22 and the function display 2 are black.
3 is colored white, but this invention is not limited to this; for example, the display 13 and the back surface 21 of the panel may be colored white, and the indicator 22, etc. may be colored black. Furthermore, it goes without saying that the coloring of each part is not limited to black or white, but any two colors with different lightness, or more colors as necessary. Furthermore, the same effect can be obtained by making the white part transparent or by forming a particularly white display part by engraving, since it is possible to obtain a difference in brightness from other parts.

(F) Effect The changeover switch mounting structure according to this invention is such that the flange of the knob on which the display is attached is made transparent, and the color of the display and the background panel are approximately the same brightness. Since the panel portion is colored in a color with a brightness difference from the above color, the indicated display can be easily recognized, and errors in reading or setting of the changeover switch can be reduced.

In addition, this changeover switch mounting structure allows the display to be seen by the difference in brightness between the color of the indicated position and the color of the display, so light-emitting elements such as lamps are used to make the display visible. However, it is not necessarily necessary.

Furthermore, since the configuration is relatively simple, it can be realized at low cost and has high practical utility value.

Claims (1)

[Scope of utility model registration request] It is equipped with a knob having a translucent flange, a display provided around the flange, and a panel located below the flange. The color is set to a color that has a brightness difference from the displayed color, and the color of the area other than the indicated position is set to approximately the same brightness as the displayed color, and the color of the part other than the indicated position is set to approximately the same brightness as the displayed color. A changeover switch mounting structure characterized in that a certain display is blended with the color of the panel and cannot be visually recognized, and a display located at a designated position on the panel is raised within the color of the designated position.
