Description

[Detailed explanation of the idea] Industrial applications This invention relates to a seesaw switch.

BACKGROUND ART Conventionally, as described in Japanese Utility Model Application No. 61-720, a switch case with a built-in switch part is provided with a rotatable knob for operating the switch part. First and second lamps are arranged in parallel in a direction perpendicular to the direction, a translucent display plate is provided at one end of the knob, and the switch part is turned on by rotating the knob, and the load such as a heater and the second lamp are turned on. Connect the lamp to the power supply and turn on the second lamp to indicate the operating status. Also, at night, turn on the lighting switch to turn on the first lamp, so you can easily locate the knob even in the dark. There is a seesaw switch that makes this clear.

In addition, as described in Japanese Utility Model Application No. 61-139529, two lamps are installed inside the switch case, and one lamp reveals the location of the knob at night, and the switch is turned on to operate the load. There is a seesaw switch that is equipped with a means for turning off a lamp for night illumination when the other lamp is turned on.

Problems that the invention aims to solve The invention described in Utility Model Application Publication No. 1983-720 illuminates the display board with a lamp to reveal the location of the knob and to display the operating status of the switch section. However, the display board is placed close to the end of the knob so that the shadow of the shaft, which is the fulcrum of rotation of the knob, cannot be seen. Therefore, in order to operate the knob, the user must place his or her finger on the display board, which tends to get dirty and make it difficult to see the display status. Increasing the brightness of the lamp will make it easier to see even if the display board is dirty, but power consumption will increase. In particular, when a load is connected to a power source at night, power consumption increases because a night illumination lamp and an operation display lamp are turned on. In addition, the switch case requires space to allow the rotation of the knob, but by arranging the first and second lamps in the direction perpendicular to the rotation direction of the knob, the switch case can only be used in the width direction. Therefore, it must be made larger in the thickness direction as well. As a result, the operating sound of the knob reverberates inside the switch case, making it unpleasant to the ears.

In addition, the idea described in Japanese Utility Model Application Publication No. 61-139529 reduces power consumption by turning off the night illumination lamp when the load and the lamp that displays the operating status of this load are connected to the power source at night. However, since two lamps are required, there must be enough space inside the switch case.

Furthermore, since it is necessary to change the emission color of the two lamps, two types of lamps are required, and work such as covering the lamps with caps of different colors is required, which increases the number of assembly steps.

Means for Solving the Problem: Inside a switch case containing a built-in switch section for connecting a load to a power source, there is a switch that is connected to the power source via the switch section and also connected to the power source via a lighting switch. A light-emitting element is provided, and the switch case is rotatably provided with an operation member having a translucent display section and a lens that partially faces the inside of the display section, and the switch case interferes with the switch section. A portion is provided on the lens to form first and second light-receiving surfaces on the lens that are colored in different colors and alternately face the light-emitting element by rotational movement of the operating member.

Function: Therefore, when the operating member is rotated, the switch section is operated by the switch switching section, the load and the light emitting element are connected to the power source, and the second light receiving surface of the lens is made to face the light emitting element, and the light emitting element is The operating status of the load is displayed by transmitting the light from the display section, and at night, the light emitting element is connected to the power source by the lighting switch, the first light receiving surface of the lens is faced to the light emitting element, and the light from the light emitting element is displayed. The location of the operating member is made clear by transmitting light from the display section. At this time, by coloring the first and second light-receiving surfaces in different colors, the lighting state at night and the state indicating the operation of the load are clearly distinguished. This allows only one light-emitting element to be used, thereby reducing the size of the switch case, reducing power consumption, and reducing the number of assembly steps.

Embodiment A first embodiment of this invention will be described based on FIGS. 1 to 3. Reference numeral 1 denotes a switch case with an opening on one side, and an operating member 2 is rotatably attached to the switch case 1 via a shaft 3. The operating member 2 includes an opaque knob 4, a display section 5 located at the center of the knob 4 and formed of a transparent plate, and a lens 6. Engagement portions 7 are formed on both sides of the knob 4 and the lens 6, and are comprised of holes and protrusions that elastically engage with each other. The lens 6 also includes a facing surface 8 that contacts the side surface of the display section 5;
First and second light receiving surfaces 9 and 10 are formed that are arranged along the rotational direction of the operating member 2. Although these first and second light-receiving surfaces 9 and 10 are colored by means such as painting, their translucency is maintained. The color of the first light receiving surface 9 is, for example, green, and the color of the second light receiving surface 10 is, for example, orange. The switch case 1 also includes one lamp 1 which is a light emitting element.
1 is provided.

Furthermore, the board 1 fixed to the switch case 1
2 is provided with a seesaw type switch section 13. This switch part 13 is connected to the conductive connection plate 1
It consists of a movable contact plate 15 which is swingably held at 4 and fixed contacts 16 and 17. Further, in the center of the lens 6, a pusher 18, which is a switch switching section, is biased by a spring 19 and held so as to be swingable. This switch section 13 is for connecting the lamp 11 and a load such as a fog lamp (not shown) to a power source. Further, the lamp 11 is also connected to a power source by a lighting switch (not shown).

In such a configuration, the state shown in FIG. 1 is a state in which the load and lamp 11 are disconnected from the power source. When the operating member 2 is rotated clockwise from the state shown in FIG. 1 to the position shown in FIG. The movable contact plate 15 rotates counterclockwise and contacts the fixed contact 16.
As a result, the load and the lamp 11 are connected to the power source, the second light-receiving surface 10 of the lens 6 faces the lamp 11, and the light beam of the lamp 11 enters the orange second light-receiving surface 10, and the lens 6 Light is transmitted from the display section 5 through the display section 5. The operating state of the load can be recognized by this transparent state. And operation member 2
1, the presser 18 moves from the left side of the movable contact plate 15 to the right side of the movable contact plate 15 over the connecting plate 14, which serves as a fulcrum, as shown in FIG. The fixed contact 16 rotates in the direction
The lamp 11 and the load are separated from the power supply.

In addition, in the state shown in FIG. 1, the first light-receiving surface 9 faces the lamp 11, and when the lighting switch is turned on in this state, the lamp 11 lights up and this light enters the green first light-receiving surface 9. Light is transmitted from the display section 5 through the lens 6. Therefore, the location of the operating member 2 can be recognized even at night. When the operating member 2 is rotated clockwise in this state, the movable contact plate 15 is rotated counterclockwise and comes into contact with the fixed contact 16, as shown in FIG. As a result, the load and the lamp 11 are connected to the power source via the switch section 13, and the second light receiving surface 10 of the lens 6 is connected to the power source via the switch section 13.
faces the lamp 11 , and the light beam from the lamp 11 enters the orange second light-receiving surface 10 and is transmitted from the display section 5 through the lens 6 . The operating state of the load can be recognized by this transparent state.

As described above, by turning the operating member 2 to make the first and second light receiving surfaces 9 and 10 face the lamp 11 and changing the color of light transmitted in the display section 5, the lamp 11 and the display section 5 This makes it possible to reduce the internal volume of the switch case 1 and prevent echoes of sound when the operating member 2 is rotated.

In addition, by guiding the light beam from the lamp 11 to the display section 5, even if the display section 5 is positioned at the center of the operation member 2, the shadow of the shaft 3, which is the rotational fulcrum of the operation member 2, will not appear on the display section 5. do not have. Therefore, when the finger is placed on the end of the operating member 2 and operated, the finger touches the display section 5.
This prevents the display unit 5 from getting dirty without touching it.
A sufficient lighting effect can be obtained with a small amount of brightness, and even if the load is operated at night, only one lamp 11 is lit, so power consumption can be reduced. Furthermore, the work of covering the lamp with a cap of a different color can be omitted.

In order to color the first and second light-receiving surfaces 9 and 10, a method may be used in which a colored thin piece of synthetic resin such as polycarbonate is adhered to the colorless and transparent lens 6 using double-sided adhesive tape, or the lens 6 may be colored. It is also possible to use a method of printing and coloring the lens 6, or a method of coloring the surface of the lens 6 by two-color molding.

Further, as shown in FIG. 1, when the first light receiving surface 9 faces the lamp 11, the incident angle of the light beam of the lamp 11 with respect to the first light receiving surface 9 is small, and the second light receiving surface 10 Since the angle of incidence of the light rays from the lamp 11 on the light receiving surface increases, many light rays pass through the first light-receiving surface 9, but fewer light rays pass through the second light-receiving surface 10, where reflection takes priority. As a result, the color of the first light-receiving surface 9 overcomes the color of the second light-receiving surface 10, and the light beam transmitted from the display section 5 becomes green.
Conversely, as shown in FIG. 2, when the second light-receiving surface 10 faces the lamp 11, the angle of incidence of the light beam of the lamp 11 with respect to the second light-receiving surface 10 is small, and the first light-receiving surface Since the angle of incidence of the light rays from the lamp 11 with respect to the light receiving surface 9 becomes large, more light rays pass through the second light receiving surface 10, but fewer light rays pass through the first light receiving surface 9 due to priority of reflection. As a result, the color of the second light receiving surface 10 overcomes the color of the first light receiving surface 9,
The light beam transmitted from the display section 5 becomes orange. However, although there is some color mixing of green and orange, the distinction between the night illumination state and the operation display state is clear.

Next, a second embodiment of this invention will be explained based on FIGS. 4 and 5. The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, a projecting piece 20 that projects at an acute angle toward the lamp 11 is formed on the lens 6, and a first light receiving surface 9 and a second light receiving surface are formed in V-shaped recesses formed on both sides of this projecting piece 20. 10.

Therefore, as shown in FIG.
3 is OFF, the first light-receiving surface 9 passes the light rays of the lamp 11 toward the display section 5, or the light rays traveling from the first light-receiving surface 9 to the second light-receiving surface 10 pass through the lens 6.
Transparent to the outside. Further, as shown in FIG. 5, when the switch section 13 is ON, the second light-receiving surface 10 passes the light beam of the lamp 11 toward the display section 5, but the second light-receiving surface 10 passes the light beam of the lamp 11 toward the display section 5. Light rays directed towards surface 9 are transmitted to the outside of lens 6. Therefore, color mixing of green and orange can be prevented.

Effects of the invention Since this invention is configured as described above, the light beam of the light emitting element enters from the first light receiving surface to illuminate the display section to clarify the location of the operating member, and the light beam of the light emitting element enters the second light receiving surface. The operating status of the load can be displayed by entering the light from the light-receiving surface of the display unit and illuminating the display unit.This allows only one light-emitting element and display unit to be required, thereby reducing the size of the switch case. At the same time, power consumption can be saved, and since only one light-emitting element is used, the work of covering the light-emitting element with a cap of a different color is omitted, and the number of assembly steps can be reduced.
