Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a switch with an indicator used for a power window switch or the like of a vehicle.

[Conventional technology]

A power window switch of a conventional vehicle has an internal switch 102 mounted on an internal switch substrate 101, as shown in its external perspective view in FIG. 4 and its longitudinal sectional view in FIG.
The internal switch 102 has a switch terminal 103 on the bottom as shown.
The operation knobs 104a and 104b, which are movable pieces, project from the side surface of the movable knob. Well, power window switch case 105
The switch knob 106 and the actuator 107 are rotatably held by the switch knob 106 and are configured to drive the operation knobs 104a and 104b in the left-right direction. And switch knob 10 at night
While the power window is operating by indicating the operation direction of 6 or 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 108 and a cylindrical reflector 111 are attached to the illumination substrate to display the operation.

[Problems to be solved by the device]

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 is complicated and the number of parts is large and the cost is high. was there. In addition, it is difficult to make the power window switch module thinner.

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

[Means for Solving the Problems]

The present invention is a switch with a display, a switch base having fixed contacts on the bottom surface and switch terminals provided on both sides at a predetermined pitch (3a to 3d) or at a pitch (3e to 3f) that is an integral multiple of the predetermined pitch. , A cylindrical terminal holder portion having a movable contact held in the switch base and a switch cover covering the upper part of the switch base, and holding a terminal of the display unit, a terminal of the display unit and a switch terminal. Provided on both side walls of the switch base so that the distance between them is equal to the specified pitch or an integral multiple of the specified pitch, the display body is placed on the upper surface of the switch cover, and the terminals of the display are held by the terminal holder part. It is characterized by having done.

[Action]

According to the present invention having such characteristics, the switch base is provided with the switch terminals having a predetermined pitch on both sides or a pitch which is an integral multiple of the pitch, and the indicator is attached to the switch cover covering the switch base. 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.

[Effect of device]

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.

[Explanation of Examples]

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 as a fixed contact on the bottom surface. The lead frame is formed as a fixed contact and a common contact of the switch, and the tip is cut and bent as shown in the figure at a position 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. Switch base 2
The center part is partitioned off, and rectangular openings 2a, 2b are formed in the longitudinal direction in the side wall of each part as shown in the figure.
And switch terminals 3a, 3e formed by lead frame
On the side of the above, terminal holder portions 4a, 4b having vertical cylindrical openings at the same intervals as the switch terminals are formed on both sides thereof. Now, movable contacts 5 and 6 are inserted into the respective partitioned parts in the switch base 2, and movable pieces 9 and 10 are provided via spring retainers 7 and 8 whose central parts are curved. Movable piece 9,1
As for 0, as shown in FIG. 1, operation pieces 9a and 10a are provided on the side. A cylindrical opening is provided along the longitudinal direction, and return springs 11 and 12 are inserted in the opening. Movable piece
A spring retainer with a curved center portion is placed in the groove on the top surface of 9,10.
Is installed. A cover 15 covering the opening is attached to the upper part 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. The element holder portion 16 is a cylindrical protrusion having a hollow at the center. Further, 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.

By the way, when assembling this slide switch, the movable contacts 5 and 6 and the spring retainers 7, 8, 13 and
14 and the operation pieces 9a, 10a of the movable pieces 9, 10 are inserted so as to project from the openings 2a, 2b, and the upper opening is covered with the cover 15 and fixed.
And a display element, for example, terminals 18a, 18 of the light emitting diode 18
b is the protrusion 17a, 17b and the element holder portion 4 of the switch base 2
The elements 18c are inserted into a and 4b, respectively, and the elements 18c are fixed so as to be held by the element holder portion 16. By doing so, 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, an indicator is mounted on the printed circuit board 20 on which the slide switch 1 is mounted. The pattern can be formed at the same time so that the display can be attached to the switch module without using a dedicated pattern for the display. In FIG. 3, the switch case 105 is formed thinner than that in FIG. 5, the switch knob 106 is rotatably attached to the switch case, and the actuator 107 operates the operation pieces 9a, 10a of the movable piece of the slide switch. This is the same as 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, the slide switch with a display according to the present invention can be used alone or can be used by being incorporated in other switch modules. Needless to say.

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 push button switches.
