Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a three-color light-emitting button switch having a light-emitting diode that is linked to a switch in a telephone or the like.

2. Prior Art FIG. 1 is an external perspective view of a conventional button telephone having a channel selection button and a light emitting diode that lights up correspondingly to the button, and FIG. 2 is a sectional view of the button switch portion.

The configuration of this conventional example will be explained below with reference to FIGS. 1 and 2. In Figure 1, 1,
1' is a channel selection button, and 2 and 2' are transparent parts that diffuse the light from the light emitting diode. In FIG. 2, 3 and 3' are light emitting diodes, 4 and 4' are rubber contacts, and 5 and 5' are contacts provided on the printed circuit board 7, which correspond to the rubber contacts 4 and 4'. 6
is the top cover.

Next, the operation of the above conventional example will be explained. Second
In the figure, by pressing the channel selection buttons 1 and 1', the rubber contacts 4 and 4' are connected to the contacts 5 and 5 of the printed circuit board 7.
5', this turns on the circuit of the printed circuit board 7, causing the light emitting diodes 3 and 3' to emit light.
The structure is such that lighting is confirmed by diffusing the light through the transmitting parts 2 and 2'.

Problems to be Solved by the Invention However, in the above-mentioned conventional technology, the channel selection button and the transparent part are separated, and a light emitting diode display corresponds to each channel selection button.
For this reason, as shown in FIG. 1, when there are a large number of channel selection buttons, there is a problem in that the width of the case becomes wide.

The present invention solves the above-mentioned conventional problems, and allows the switch buttons to be configured without increasing the width of the case when configuring a large number of channel selection buttons and corresponding displays using light emitting diodes. With one switch button, 3
Three operating states can be distinguished and displayed.
The object of the present invention is to provide a color-emitting button switch.

Means for Solving the Problems In order to achieve the above object, the present invention arranges a two-color light emitting diode below the transparent part of one switch button, and connects two contacts to energize the light emitting diode for each color. 2.
Two rubber contacts are provided on the switch button to correspond to these contacts.

Therefore, according to the present invention, a two-color light emitting diode is provided below one switch button, so that one switch button can cause the two-color light emitting diode to emit light in three colors.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is an external perspective view of a telephone according to an embodiment of the present invention. In Fig. 3, the switch buttons are channel selection buttons 9, 9', transparent part 1
Consists of 0. FIG. 4 shows a cross-sectional view of the three-color light-emitting button switch, and shows the transparent part 10.
is provided between the channel selection button 9 and the channel selection button 9', and is made of a material that diffuses the light emitting diode 11. Rubber contacts 12 and 12' are provided below the channel selection buttons 9 and 9', respectively, via a transmission section 15. 14 is a top cover, and on the printed circuit board 16 are chips of two colors (red and green).
a light emitting diode 11 with a rubber contact 12,1
Contacts 13, 13' are provided which make contact with 2'. When the rubber contacts 12 and 12' come into contact with the contacts 13 and 13' on the printed circuit board 16, one chip (red or green) of the light emitting diode is activated.
The circuit is configured such that when the rubber contacts 12, 12' and the contacts 13, 13' on the printed circuit board come into contact at the same time, the two chips of the light emitting diodes emit light.

The operation of the above embodiment will be explained. In FIG. 4, when the channel selection button 9 is pressed, the rubber contact 12 and the contact 13 on the printed circuit board 16 come into contact, turning on the circuit. As a result, one chip (red) of the light emitting diode lights up, the light is diffused through the transmission part 10, and lighting is confirmed. On the other hand, when the channel selection button 9' is pressed, the rubber contact 12' and the contact 13' on the printed circuit board 16 similarly come into contact, turning on another circuit, which turns on one chip (green) of the light emitting diode 11. lights up. In addition, when the selection buttons 9 and 9' are pressed at the same time, the rubber contacts 12 and 12' and the contacts 13 and 13 on the printed circuit board 16,
13' comes into contact with the light emitting diode 11.
The two chips emit light and the orange color lights up.

As described above, according to the above embodiment, by configuring two channel selection buttons with one switch button, the width of the telephone can be narrowed, and
When you press the channel selection button 9, the red color lights up, when you press the channel selection button 9', the green color lights up, and when you press both, the orange color lights up. This has the effect of being able to distinguish and display three operating states.

Effects of the Invention As is clear from the above embodiment, the present invention provides a two-color light emitting diode under the transparent part of one switch button, thereby making it possible to narrow the width of the case and displaying three colors. Since the operation can be performed by color-coding with one switch button, it has the effect that the three operating states can be distinguished and displayed.
