Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a switch device that includes a light emitting body and uses the light emitted by the light emitting body to indicate a switch operation or the like.

(Prior Art) Conventionally, this type of switch device has a switch case equipped with an operator, a light emitting body, and a switch section, and based on the operation of the operator, the switch section is caused to perform a switch operation, and the light emitting body is It is provided by a structure that emits light from its body and from a light emitting port. Generally, in this type of switch device, the presence or absence of a switch operation is determined based on the presence or absence of light, such as whether light is not emitted or light is emitted.

(Problem to be solved by the invention) Recently, it has been considered to provide a colored body that can emit light so that it is possible to judge the difference in the operation mode of the switch based on the difference in the color of the light. However, simply providing a colored body has low added value, and there is a demand for effective use of this colored body.

Therefore, an object of the present invention is to provide a switch device in which the operating state of a switch can be determined by a change in the color of light, and furthermore, this colored body part can be used to form other switch parts. .

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a switch case with an operator, a light emitting body, and a switch section, and causes the switch section to perform a switch operation based on the operation of the operator. In the device that causes the light emitting body to emit light and emits light from the light emitting port, the operator is provided with a colored body that is movably capable of emitting light, and the colored body is attached to the switch case as the operator is operated. A feature is that a guide part consisting of a fixed contact piece that is guided and moved to be positioned between the light emitting body and the light emitting port is provided, and a movable contact piece that comes into contact with the guide part is provided on the colored body. have

(Function) According to the above means, the operator is provided with a colored body capable of emitting light in a movable manner, and the colored body is guided and moved in the switch case in accordance with the operation of the operator, thereby connecting the light emitting body and the light emitting body. Since a guide section is provided to be positioned between the light emitting body and the mouth, based on the operation of the operator, the colored object is guided to the guide section and positioned between the light emitting body and the light emitting port. . Therefore, the color of the light emitted from the light emitter changes depending on whether it passes through the colored body or not. Thereby, the operating state of the switch can be determined by the change in the color of the light. Furthermore, by forming the guide part from a fixed contact piece and providing the colored body with a movable contact piece that contacts the guide part, it can be used to form other switch parts.

(Embodiment) Hereinafter, one embodiment of the present invention applied to a switch device for a so-called air conditioner (air conditioner) of an automobile will be described with reference to the drawings. First, in Figures 1 and 2, 1 is the switch base 2.
The switch case is composed of a switch cover 3 and a switch cover 3, and a holder 4 is provided protruding from the right end of the switch case. A light emitting body 5 such as a lamp is disposed inside the switch case 1, and three fixed contact pieces 6, 6 and 6a (third
(see figure) is provided. Reference numeral 7 denotes an operator, which includes a hollow push button 8 provided in the holder 4 so as to be movable in the left-right direction, and a colorless and transparent moving body whose base end is fitted and connected to a through hole 8a of the push button 8. 9, and the outer opening of the through hole 8a of the push button 8 serves as a light emitting port 10. Furthermore, this light emitting port 10
A transparent panel body 10a is attached to the panel body 10a. A space 11 is formed in the movable body 9 at a portion located inside the switch case 1 to allow the light emitting body 5 to escape, and three contact portions are provided at the lower part of the tip (left end) of the movable body 9. A movable contact piece 12 having 12a, 12a and 12b (see FIG. 3) is arranged together with a spring 13. This movable contact piece 12 and the three fixed contact pieces 6, 6, and 6a constitute a switch portion 14. Reference numeral 15 denotes a spring provided in the holder 4, which returns the operator 7 to the right. Reference numeral 16 denotes a lock mechanism, which is composed of a lock base 17 disposed on the top of the tip of the movable body 9, and a lock lever 18 that moves relatively on the lock base 17. It engages with the first recess 17a and second recess 17b in the base 17, and moves the operator 7 to the first lock position (FIG. 5) and the second lock position (sixth lock position).
(Fig.). Reference numeral 19 is a translucent colored body, for example green, in which a cutout recess 19a is formed as shown in FIG. The colored body 10 is provided at the right end of a space 11 in the movable body 9 of the operator 7 so as to be able to move up and down, and is always urged against the upper surface of the switch base 2 by a spring 20. Further, a movable contact piece 21 is attached to the lower part of the colored body 19 as shown in FIG.
In the state shown in FIG. 1, the colored body 19 is located slightly below the light emitter 5 and the light emitting port 10. 2
Reference numeral 2 designates a pair of guide parts disposed in front of the light emitter 5 in the switch base 2 of the switch case 1, which is connected to the fixed contact piece that forms the switch part 23 with the movable contact piece 21 of the colored body 19. The first flat surface portion 22a is flush with the upper surface of the switch base 2, the slope portion 22b is continuous with the first flat surface portion 22a, and the second slope portion 22b is continuous with the upper end portion of the slope portion 22b.
It has a flat surface portion 22c.

Next, we will discuss the effect. From the state shown in Figure 1, the operator 7
is held in the first locked position by the locking mechanism 16 by pressing it to the left (see FIG. 5). Then, the two fixed contact pieces 6,
6 is short-circuited by the movable contact piece 12 to perform the first switch operation, and as a result, the light emitter 5 is turned on and the air conditioner (not shown) is operated at a lower operating rate than normal, resulting in so-called "economy operation". ” will be carried out. Further, in this first lock position, the colored body 19 is attached to the first flat surface portion 22a of the guide portion 22.
As a result, the pair of guide parts 22 in the switch part 23 are short-circuited by the movable contact piece 21,
That is, the switch is operated to light an illumination lamp of an instrument panel (not shown) that is different from the light emitter 5. Here, since the colored body 19 is located on the first flat surface portion 22a that is flush with the switch base 2, there is no change in height, so that the orange color (emission color of the light emitter 5) from the light emitter 5 is emitted from the light emitter 5. The light passes through the notched recess 19a of the colored body 19, passes through the colorless and transparent moving body 9, and is emitted from the light emitting port 10 in its orange color, thereby indicating that the air conditioner is in the "economy operation" state. . Next, the operator 7 is further pressed and held at the second lock position by the lock mechanism 16 (see FIG. 6). Then, the three fixed contact pieces 6, 6, and 6a are short-circuited by the movable contact piece 12 in the switch part 14, and a second switch operation is performed, whereby the light emitting body 5 remains lit and the air conditioner operates normally. The so-called "standard operation" is performed by operating at a certain rate. On the other hand, the colored body 19 is moved from the first flat surface part 22a of the guide part 22 through the slope part 22b to the second flat surface part 22c by the operation of the operator 7. is higher than in the locked position, and the light emitter 5
and the light emitting port 10. Therefore, the light from the light emitter 5 passes through the colored body 19, and as a result, green light is emitted from the light emitting port 10, thereby indicating that the air conditioner is in the "normal operation" state. . In this case, since the movable contact piece 21 of the colored body 19 slides while being in contact with the guide section 22, there is no change in the switch operation of the switch section 23. If the operator 7 is further pressed after this, the lock by the lock mechanism 16 is released, so the operator 7 is returned to the position shown in FIG. 1, and the switch section 14 and the switch section 23 are respectively turned off. .

Furthermore, in the above case, the guide part 22 is composed of a fixed contact piece, and the colored body 19 is provided with the movable contact piece 21 that contacts this guide part 22, so that the colored body 19 and the guide part 22 are connected to the switch part 14. can be used to form another switch section 23.

In the above embodiment, the illumination lamp of the instrument panel (not shown) is turned on by the switch operation of the switch section 23, but the light emitting body 5 may be turned on, for example.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope of the invention, for example, it can be applied not only to automobile air conditioners but also as a switch device for various types of equipment.
