This invention relates to a switch device in which a mode and a push button with a two-mode display can be exchanged.

[Conventional technology]

2. Description of the Related Art Recently, vehicles and the like are equipped with many devices in order to meet the diversified demands of users. The operation switches for these various devices are concentrated in one place, making operations easier and at the same time making the device more compact.

A switch incorporated in a conventional mode panel includes, for example, a switch equipped with a one-stage lock mechanism disclosed in Japanese Utility Model Application Publication No. 126128/1983. Therefore, the mode switching mechanism is composed of a large number of switches and push buttons for operating the switches. Also, when installing new equipment as an option, the switch, switch operation unit, and electrical wiring for operating the equipment are changed.

In particular, when installing a new device or changing the specifications of an existing device on a mode panel that has operation switches for various devices gathered in one place, it is necessary to convert the mode panel itself or remove the mode panel from the vehicle body. , After removing the old switch, install the new switch. After redoing the electrical wiring and assembling the switch operation section, lighting section, push buttons, etc., the mode panel was attached to the vehicle body.

[The problem that the idea attempts to solve]

In this way, conventional mode panels are composed of switches with a one-stage locking mechanism, so in order to satisfy the request for multiple mode changes, many switches must be used, and the mode panel becomes Become larger. In addition, because the operating devices including switches are not compatible with newly installed equipment, the mode panel itself must be replaced each time, or the mode panel must be removed from the vehicle body and some parts replaced, making it extremely difficult. There is a problem of poor workability.

The purpose of this invention is to operate a switch device equipped with a two-stage lock mechanism switch and an illumination mechanism that displays two modes as a one-stage lock and one mode display switch device.

[Means to solve the problem]

The above object consists of a vertical first light guide that is divided into two parts that are optically independent from each other, and a reflective surface that guides light from the horizontal direction at the bottom of both of the first vertical light guides. and a switch operating body that is slidably supported so that the vertical first light guide projects from the switch case, and a switch operating body that is attached to a lower end portion of the switch operating body that is located inside the switch case. a switch with a two-stage locking mechanism, a first light guide in the horizontal direction corresponding to the reflective surface of the switch operating body when the switch is turned off, and a first light guide in the horizontal direction provided at the open end of the first light guide in the horizontal direction. a first light source; a lateral second light guide corresponding to the reflective surface of the switch operating body when the switch is in the first and second stage lock; and an open end of the lateral second light guide. a second light source provided in the lateral direction, a first shield body is interposed between the lateral first light guide and the lateral second light guide; The light guide has an illumination section provided with a second shingle body facing the reflective surface on the opposite side from the second light source when the switch operating body is locked in the first stage, and a single mode display on the top surface. A mark plate is fixed, and a restriction part is provided to prevent the switch from being pushed from the first stage to the second stage lock, and a first light guide in the vertical direction of the switch operating body is provided on the lower surface of the mark plate. A light diffuser for diffusing light from one side is provided, a first push button that is detachable from the switch operating body, and a mark plate with a two-mode display on the top surface are fixed to the first and second stages of the switch. This is achieved by including a mechanism that allows the switch to be pushed into the step lock, and in combination with a second push button that is detachable from the switch operating body.

[Effect]

According to the above configuration, when only the first stage lock is used, the first push button is attached to the switch operating body. And when non-mode is selected (when switch is OFF)
In this case, the reflective surface of the switch operation body is located on the first light guide in the lateral direction, but if it is daytime and the first light source is turned off, the first push button is not illuminated. next,
When the first push button is pressed down to select the first stage mode, the reflective surface of the switch operating body moves from the first lateral light guide to the first position of the second lateral light guide. Then, the light emitted from the second light source of the second light guide in the horizontal direction is reflected on the reflective surface that does not face the shield plate, and the light emitted from the first light guide in the vertical direction corresponding to the reflective surface is reflected. After passing, the light is diffused by a light diffuser having a light diffusing means provided on the first push button, brightly illuminating the entire surface of the first push button. At this point, when the first push button is pushed down further, the restriction part provided on the first push button comes into contact with a part of the switch case, preventing further movement and making it impossible to enter the second stage lock state. .

On the other hand, when using the first and second stage locks, a second push button is attached to the switch operating body. When non-mode is selected, the usage is the same as above, so
The second pushbutton is not illuminated. First, when the second push button is pressed down to select the first stage mode, the reflective surface of the switch operating body moves from the first horizontal light guide to the first position of the second horizontal light guide. This horizontal second light guide is provided with a shield plate to prevent direct entry of light, so the light emitted from the second light source is transmitted to each reflecting surface with a difference in illuminance. , and illuminates one side of the second push button brightly and dimly illuminates the other half through the first vertical light guide and the second vertical light guide provided on the second push button. An illumination display indicates that the first stage mode has been selected. Furthermore, when the second push button is pressed down to select the second stage mode, the reflective surface of the switch operating body moves to the second position of the second light guide in the lateral direction. In this position, the incident light is reflected by both reflective surfaces, illuminates the entire surface of the second push button through the first light guides in both vertical directions and the second light guides in both vertical directions of the second push button, and illuminates the entire surface of the second push button. An illumination display indicates that the two-stage mode has been selected. When used in a dark environment such as at night, if the first light source of the first light guide in the horizontal direction is turned on, it will be reflected by both reflective surfaces of the switch operation body when the non-mode is selected, and the light will be reflected in both vertical and vertical directions. The entire surfaces of the first and second push buttons can be illuminated through the first light guide in the direction.
