Description

[Detailed description of the invention] The present invention relates to a switch device that brightly displays a push button by reflecting external light without using a light source.
To provide a device capable of displaying a larger display by slightly increasing the brim of a push button.

An example of a conventional switch device is shown in FIGS. 1 and 2.

A board 7 (to which the switch body B is attached) has a sliding rod 6 protruding from the board 7 that turns the switch body 8 on and off.

A push button main body 6 slides within a frame 4 located above the substrate 7, the lower end of the push button main body 5 abuts the tip of the sliding rod 6, the upper end has an inclined surface 9, and further It has a protruding piece 10 extending upward.

Reference numeral 1 indicates a push button made of a transparent material, and the lower surface thereof is the push button body 5.
It has an inclined surface 2 that extends along the inclined surface 9c, and is connected to the push button main body 5 by adhesive or the like.

A colored surface 3 is formed on the inner surface of the frame 4 which faces the inclined surface 2 when the push button 1 is pushed in.

The push button 1 is made of a material that totally reflects external light when it is incident, and the inclined surface 2 acts as a reflective surface.

FIG. 1 shows the state in which the push button 1 is pushed in, and the switch body 8 assumes a first state with the sliding rod 6 pushed in. At this time, the inclined surface 2 of the push button 1 is exactly opposite to the colored surface 3.

For this reason, the external light that enters the push button 1 hits the inclined surface 2 and illuminates the colored surface 3, and the light hits the inclined surface 2 again and is reflected and returns to the outside. When you look at 1, the transparent push button 1 looks as if it has been colored.

One solution (Fig. 2) (As shown in this figure, when the push button 1 is not pressed, the push button 1 protrudes from the frame 4 due to the spring force of the switch body 8, so the inclined surface 2 and the colored surface 3 do not face each other, and the push button 1
has its own color (it cannot be seen in its colored state).

The purpose of the present invention is to improve the above-mentioned conventional switch device, and to effectively utilize the area of the pushbutton brim when the pushbutton switch 5 is in the single state to display a bright and large colored display using external light. .

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, the same reference numerals as in FIGS. 1 and 2 are given to the Fl- portions for explanation.

A reflector 12 made of the same material as the push button 1 is fixed inside the frame 4 along the push button 1.

The lower surface of this reflector 12 is formed with an inclined surface 13 that faces the inclined surface 2 of the push button 1, and the lower surface of the reflector 12 that faces the push button 1 is
In this way, colored surfaces 3 are formed at the sandwiched points.

The reflector 12 is connected to the push button 1. It is fixed to the frame 4 so as not to move together with the push button body 5.

Further, the upper end of the push button 1 is provided with a planar flange 11 that covers the upper surface of the reflector 12.

The upper end of the push button body 5 has a cylindrical body projecting in the horizontal direction.
The entire upper opening end of this cylindrical body (the collar 11 of the push button 1 comes into contact with it).

When the push button 1 is pushed in, as shown in Fig. 3,
The switch body 8 is in the first state when the sliding rod 6 is pushed in, and the inclined surface 2 of the push button 1 and the inclined surface 13 of the reflector 12 are positioned opposite to each other with the colored surface 3 in between.

Therefore, the external light incident from the push button 1 is reflected by the inclined surface 2, transmitted through the colored surface 3, and reflected by the inclined surface 13 of the reflector 1.
2 and appears on the surface of the collar 11.

Further, external light incident on the collar 11 is reflected by the inclined surface 13, transmitted through the colored surface 3, reflected by the inclined surface 2, passes through the inside of the push button 1, and appears on the surface of the push button 1.

In addition to the above, light incident from various directions is reflected in various ways and returns to the surface (muffled).

Therefore, the reflected light on the surface of the push button 1, including the part 11, looks bright and bright, and the color of the colored surface 3 makes it look as if it has been colored, so a push button with a large and bright display surface can be obtained. It is something.

The flange 11 is in contact with the entire upper open end of the cylindrical body 5 of the push button, so that even if the flange 11 is pressed, a good switching operation can be performed.

On the other hand, when the push button 1 is not pushed in, the switch body 8 is not pushed in and is in the second state, as shown in FIG. 4, and the inclined surface 2 of the push button 1 and the inclined surface 13 of the reflector 12 do not face each other. .

Further, a space 14 is created between the flange 11 and the upper surface of the reflector 12.

In this state, the light incident from the push button 1 does not face the colored surface 3, so the reflected light is not colored, and the light incident from the flange 11 is also affected by the reflector 12 and the colored surface 3 because the space 14 exists. does not reach a sufficient level, and as a result, the surface of the push button 1, including the collar 11, is not colored.

In the switch device of this invention, the surface of the pushbutton brim is sufficiently large, and when the pushbutton is operated, the entire pushbutton brim appears colored, making it easy to clearly distinguish between the first and second states of the switch body. It can be separated by color.

Moreover, since the display uses reflected light from outside without using a light source such as a light bulb, the number of parts is small, the structure is simple and inexpensive, and maintenance costs are also low.

Moreover, the switch can be operated accurately no matter where on the brim you press.

In addition, in the above embodiment, when the push button is pressed down, the push button appears colored, but by changing the position of the reflector, it can be made to appear colored when the push button is not pressed. is also possible.
