Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch device equipped with a lighting device.

For example, in a switch device installed in a car,
A switch and a lighting device, such as a lamp for night lighting, are arranged inside the switch case, and a knob for controlling the opening and closing of the switch is positioned in the opening of the switch case so that it can be moved in the axial and circumferential directions. A switch case is provided in which the switch case is attached to an instrument panel of an automobile such that the knob thereof is located on the front side of the instrument panel. However, in this type of switch device, since the opening of the switch case is traditionally closed by a knob, the lamp is attached to the inner wall of the switch case so that it can be attached and detached from the rear, so it is difficult to replace the lamp. In this case, the switch case had to be removed from the instrument panel, which was extremely inconvenient.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a very convenient switch device that allows the lighting fixture to be replaced while the switch case is attached to the mounting board.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a substantially cylindrical switch case having an intermediate partition wall 2, and both end faces thereof are open.

(See Figure 3). One ends of the fixed contacts 18, 19 and 20 are provided with a common terminal 18a and a setting terminal 19 on the left side surface of the terminal board 8, respectively, as shown in FIG.
a and a resume terminal 20a. On the other hand, 22 shown in FIG.
This is a movable contact piece made of a leaf spring attached opposite to the pressing part 7, and its base end 22a is connected to the common terminal 18a by printed wiring. Reference numeral 23 shown in FIGS. 3 and 5 is a fixed contact piece disposed on the terminal plate 8 facing the contact 22b of the movable contact piece 22, and this fixed contact piece 23 and the movable contact piece 22 are used for canceling. A switch 24 is configured. Reference numeral 25 shown in FIGS. 1 and 2 is a notch formed in the opening of the right cylindrical portion 1b of the switch case 1, and 26 is a lens attached to this notch 25. Reference numerals 27 and 27 denote support strips made of a conductive material, and the opposing base ends of the support strips 27 and 27 are located on the opening 1c side of the right cylindrical portion 1b in the switch case 1. It is attached to the lens 26. Each tip 27 of this support strip 27, 27
a, 27a are led out to the outside via the terminal plate 8, as shown in FIG. The reference numeral 28 shown in FIG.
It is removably mounted in a mounting hole 30 formed between the proximal end portions 7 and 27 by a so-called bayonet method. A groove (attachment/detachment part) 31 is formed in the base body 29 facing the opening 1c for inserting an attachment/detachment tool such as a screwdriver, and a tool (not shown) can be inserted into this groove 31 and turned. This allows the attachment and detachment to be carried out. 32 shown in FIGS. 1 to 3 is an opening 1 of the cylindrical portion 1b of the switch case 1.
The knob is large enough to cover part c, and its central part is removably fixed to the right end of the shaft 4 with a screw 33, so that the knob 32 is attached to the right side of the switch case 1 in the direction of arrow B. (in the direction opposite to arrow A), in the direction of arrow C, and in the opposite direction of arrow C (see FIG. 2). The inner surface of the knob 32 is formed with protrusions 34 and 35 (see FIG. 3) that fit into the fitting recesses 16 and 17 of the rotating body 9, respectively, and the knob 32 rotates together with the rotating body 9. It's becoming like that. As a result, the rotation of the knob 32 from the original position shown in FIG. 2 in the direction of the arrow C and in the direction opposite to the arrow C is restricted by the rotating body 9 to a range of angle α, respectively, and after the rotation, the knob 32 automatically returns to the original position. It's becoming like that. Further, although not shown, the knob 32 has transparent portions shaped like the letters ``RESUME'', ``OFF'', and ``SET'' formed at portions corresponding to the lenses 26. In FIG. 1, 36 is a steel ball disposed so as to be pressed against the outer surface of the shaft 4 between the intermediate partition wall 2 of the switch case 1 and the rotating body 9.
37 is a groove formed in the shaft 4. Therefore, the groove 3
Reference numeral 7 indicates that when the shaft 4 is moved in the direction of arrow B by pushing the knob 32, it engages with the steel ball 36 to give the user a sense of moderation. Here, the switch case 1 is assembled into an instrument panel 38 of an automobile, which is a mounting board, and the switch device configured as described above constitutes a switch device in a speed control device of an automobile.
The lamp 28 is turned on at night together with the vehicle side lights, etc., and emits light from the transparent portions indicating the above-mentioned ``RESUME'', ``OFF'', and ``SET''. Further, the setting terminal 19a and the common terminal 18a of the switch 21 are closed by rotating the knob 32 in the direction of arrow C to generate a set signal.
The speed of the vehicle is now set to the actual speed at the time of this operation.
Further, the cancel switch 24 is closed by pressing the knob 32 in the direction of arrow B to generate a cancel signal, thereby canceling the above-mentioned set state. Then, the connection between the resume terminal 20a and the common terminal 18a of the switch 21 is closed by rotating the knob 32 in the opposite direction of arrow C to generate a resume signal, whereby the speed of the vehicle is set in advance. The speed is automatically set to the specified speed. The set speed is also automatically canceled when the driver steps on the accelerator or brake.

According to this embodiment having the above configuration, the knob 32
A support strip 27 for the lamp 28 is provided inside the switch case 1 on the side of the opening 1c, and a groove 31 is formed in the support strip 27 so that the lamp 28 can be attached or removed at the opening of the switch case 1. The switch case 1 is inserted through the opening 1c.
Since it faces outward, the knob 32 can be removed from the front side of the instrument panel 38, and the lamp 28 can also be removed from the front side of the instrument panel 38, making it easy to replace the lamp 28. In this case, it is not necessary to remove the switch case 1 from the instrument panel 38, which is very convenient. by the way,
The lamp 28 has a groove 31 in its base 29 which is an attachment/detachment part.
Therefore, it is necessary to arrange the base body 29 on the side of the opening 1c of the switch case 1, and in this case, there is a concern that the arrangement space at the opening 1c will be difficult. However, in this embodiment, the support strips 27, 27 that support the lamp 28 are made of a conductive material, and serve both as a conductor for supplying electricity to the lamp 28 and as a support member. In this embodiment, which is configured to be directly attached to the camera, no special support member is required, and no space is required accordingly.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but may be modified in various ways without departing from the spirit, for example, it can be applied to devices other than speed control devices for automobiles, and even to devices other than automobiles. It can be implemented by

As explained above, the present invention includes a switch case that is attached to a mounting board and has one side open, a switch provided in the switch case, and a switch that is removably and movably attached to the opening of the switch case. a knob that controls the opening and closing of the switch by its movement operation; a lens attached near the opening of the switch case; and a proximal end of the lens attached to the opening of the switch case. a support strip made of a conductive material whose tip is led out from a terminal board provided on the opposite side to the opening side; and a support strip made of a conductive material that is removably attached to the base end of the support strip and whose attachment/detachment portion is attached to the switch case. A lighting fixture having a base disposed to face the opening side, and a light-transmitting portion formed in a portion of the knob corresponding to the lens and illuminated by the lighting fixture through the lens. With this, the lighting fixture can be removed from the switch case without removing the switch case from the mounting board, making it easy and convenient to replace the lighting fixture. Even though the attachment/detachment part of the switch case is located on the opening side of the switch case, there is no need to provide a special support member in addition to the conductor for energizing the lighting equipment to support the lighting equipment, and it also requires less space. Therefore, there are various effects such as not having to worry about the space for arranging components in the opening.
