Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch with a display used for a power window switch of a vehicle.

[0002]

2. Description of the Related Art A conventional power window switch for a vehicle is shown in FIG. 4 which is an external perspective view and FIG. 5 which is a vertical sectional view thereof.
Is installed. As shown in the figure, the internal switch 102 has a switch terminal 103 formed on the bottom surface thereof, and operation knobs 104a and 104b of movable pieces project on the side surfaces thereof. Now, the power window switch case 105 has a switch knob 1
06 and the actuator 107 are rotatably held, and are configured to drive the operation knobs 104a and 104b in the left-right direction. And switch knob 106 at night
When the power window is in operation by indicating the operation direction of or by operating the internal switch 102, the display 108 such as a light emitting diode is used for display. In FIG. 5, an illumination substrate 110 is provided on the lower surface of the Zebel 109, and a display unit 108 and a cylindrical reflector 111 are attached to the illumination substrate to display the operation.

[0003]

However, according to such a conventional power window switch, since a lighting substrate for mounting a display is required independently of the switch substrate, the structure becomes complicated and the number of components is increased. However, there was a drawback that it was expensive. In addition, it is difficult to make the power window switch module thinner.

The present invention has been made in view of the above conventional problems, and it is a technical object to easily hold an indicator on an internal switch and to make a switch module thin. .

[0005]

The present invention is a switch with a display, which has fixed contacts on the bottom surface and has a predetermined pitch (3a to 3d) on both sides or an integral multiple of the predetermined pitch (3e to 3f). A tubular terminal holder part for holding the terminals of the display is provided, which has a switch base having switch terminals provided, a movable contact held in the switch base, and a switch cover covering the upper part of the switch base. ,
Provided on both side walls of the switch base so that the distance between the terminals of the display and the switch terminals is the same as the specified pitch or an integral multiple of the specified pitch. The terminal is held by a terminal holder portion.

[0006]

According to the present invention having such a feature, switch terminals having a predetermined pitch or an integral multiple of the pitch are provided on both sides of the switch base, and the indicator is attached to the switch cover covering the switch base. ing. The terminals of the display are also held by the terminal holders on both sides of the switch base, and are arranged so as to have the same predetermined pitch as the switch terminals or an integral multiple thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an assembly configuration diagram of a slide switch according to an embodiment of the present invention, and FIG. 2 is a perspective view thereof. As shown in the figure, the slide switch 1 according to the present invention is provided with a switch base 2 having a lead frame formed as a fixed contact on the bottom surface. The lead frame is formed as a fixed contact and a common contact of the switch. The lead frame is cut and bent as shown in the figure at positions close to the switch base to form the switch terminals 3a to 3f. To do. In this way, the switch terminals 3a to 3d can be terminals with the same pitch.
The switch base 2 is divided at the central portion thereof, and the side walls of each portion are provided with rectangular openings 2a, 2 in the longitudinal direction as shown in the drawing.
b is formed. Then, on the sides of the switch terminals 3a and 3e formed of the lead frame, terminal holder portions 4a and 4b having vertical cylindrical openings at the same intervals as the switch terminals are formed on both sides thereof. Now, the movable contacts 5 and 6 are inserted into the respective partitioned parts in the switch base 2, and the movable pieces 9 and 10 are provided via the spring retainers 7 and 8 whose central portions are curved. As shown in FIG. 1, the movable pieces 9 and 10 are provided with operation pieces 9a and 10a on their sides. Further, a cylindrical opening is provided along the longitudinal direction, and return springs 11 and 12 are inserted into the openings, respectively. Further, the spring retainer 1 having a curved central portion is formed in the groove on the upper surface of the movable pieces 9 and 10.
3, 14 are attached. A cover 15 that covers the opening is attached to the upper portion of the switch base 2. The cover 15 is a substantially rectangular member, and an element holder portion 16 for positioning a display element such as a light emitting diode and holding the element itself is provided on the upper surface of the cover 15. Element holder part 1
Reference numeral 6 is a cylindrical protrusion having a hollow in the center. Protrusions 17a and 17b having through holes forming a terminal holder portion are formed on the left and right sides of the cover 15 at positions having the same pitch as the terminals 3a to 3f of the lead frame.

When assembling this slide switch, the movable contacts 5 and 6, the spring retainers 7, 8, 13, and 14 and the operation pieces 9a and 10a of the movable pieces 9 and 10 described above are formed in the switch base 2 through the openings 2a and 2. 2b is projected and inserted, and the upper opening is covered and fixed by the cover 15. Then, a display element, for example, terminals 18a, 18 of the light emitting diode 18
b are inserted into the protrusions 17a and 17b and the element holder portions 4a and 4b of the switch base 2, respectively, and the element 18
The element c is held and fixed in the element holder portion 16.
In this way, the display can be fixed to the upper part of the slide switch as shown in FIG.

As shown in the longitudinal sectional view of the switch module of the power window switch in FIG. 3, when the slide switch 1 is used to form a switch module, the slide switch 1 is mounted on a printed circuit board 20. By forming the pattern of the display at the same time, the display can be attached to the switch module without using the pattern dedicated to the display. In FIG. 3, the switch case 105 is formed thinner than in FIG. 5, the switch knob 106 is rotatably attached to the switch case, and the actuator 107 operates the operation pieces 9a and 10a of the movable piece of the slide switch. This is similar to the above-mentioned conventional example. In this case, since the indicator is held on the upper portion of the slide switch, the substrate for illumination is not required, the structure is simplified, and the switch module itself can be thinned.

Although this embodiment shows an example in which the slide switch is applied to a power window switch of a vehicle,
It goes without saying that the slide switch with a display according to the present invention can be used alone or can be incorporated in another switch module for use.

Further, although the present embodiment describes the embodiment in which the display is attached to the slide switch, the present invention can be applied to other types of switches such as a push button switch.

[0012]

Therefore, according to the present invention, the switch and the indicator can be integrated, and the position and operation state of the switch can be displayed. Also, when a power window switch module is constructed using this switch with a display, a substrate for illumination is not required and the structure can be simplified. In addition, the power window switch module itself can be made thinner.
