[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of a switch, particularly a board type switch which is highly versatile and can be used in many devices and systems.

[0002]

[Background of the Invention] In recent years, switches have recently been reduced in size in accordance with the equipment to be equipped, eliminating any protrusions such as knobs on key tops, eliminating the stroke at all, or acting with a very small stroke. A membrane switch with a flat surface, with the surface of the mechanism being covered with a sheet, has also been developed.

[0003]

However, the above-mentioned membrane switch has a flat surface, which causes slippage during operation, has no clicking feeling and causes anxiety, and has a simple appearance. It is difficult to reflect the tastes of the consumers because it has become too large, and a unique material is required for the tact member to be used, which has contributed to high costs.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made mainly by focusing on the problem of the membrane switch described above, and has a click feeling that gives an operator recognition of operation while using the membrane switch as a base. To provide a switch structure capable of reducing costs by using parts whose materials are not limited and by simplifying the assembling process, while also remaining flexible to meet the tastes of consumers. It is an object.

[0005]

In order to achieve this object, the structure of the switch according to the present invention comprises a plurality of flexible switches.
Laminating the Le a wiring substrate, in the structure of the switch for connecting the pattern of the wiring substrate, possesses elasticity at the connection position between the pattern includes a variable dynamic protrusion substantially in the center lower surface
Decor rubber inverted cup-shaped member, the structure of the switch, characterized in that is attached to the top member to the top of the inverted cup-shaped member, laminated wiring board and the
A plurality of spacer boards are bonded and laminated on the
Sub-board has a small through hole in the lower spacer board
The upper spacer board is provided with a large-diameter through hole,
The base end of the inverted cup member is a lower spacer board.
Into the through hole of the upper spacer board.
And the upper surface of the lower spacer board
The key top member is provided as a stopper .

[0006]

With the above arrangement, when connecting the patterns of the laminated wiring boards, a click feeling is generated by pressing the inverted cup-shaped member and moving its movable contact, and the top member is also required. Can be changed freely. Further, since the mechanism for connecting the patterns is of a push type using an elastic material, it is possible to apply a conventional component, and assembling becomes easy, so that a significant cost reduction can be achieved.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a plan view of a switching board embodying the present invention, FIG. 2 is a sectional view of the same, FIG. 3 is a perspective view showing a top member and an inverted cup-shaped member, and FIG. 4 is a bottom view of the top member.

In the drawing, reference numeral 1 denotes a switching board embodying the present invention. The switching board 1 has a plurality of flexible wiring boards 2 and 3 and a through hole 4 above a connection between the patterns of the wiring boards 2 and 3. Are formed by sequentially bonding and laminating a plurality of spacer boards 5, 6 and a cover member 7 provided with a release sheet 8 which is peeled off when the switching board 1 is attached to an appropriate place. On the surface of the cover member 7, a decorative cover 9 describing the operation contents corresponding to the device to be used is stuck.
In addition, a part of the flexible wiring board 2 is partially protruded for connection with a device.

Further, a switch operating mechanism is attached to the through holes 4 provided in the spacer boards 5 and 6 of the switching board 1. The through hole 4 provided by the spacer boards 5 and 6 has a smaller diameter at the portion of the spacer board 5 and a larger diameter at the portion 6, and a through hole in the spacer board 5 portion has a rubber inverted cup. A hole 13 provided on the bottom surface of a top member 12 is fitted to a rectangular support portion 11 formed on the top of the inverted cup-shaped member 10 and formed around the top member 12. The provided flange 14 is engaged with the rear surface of the cover member 7 to prevent the cover member 7 from falling off.

The inverted cup-shaped member 10 is positioned at the bottom, and a movable projection 15 is integrally formed on the lower surface of the support portion 11. This movable projection 15
Is lowered by the bending of the bent side wall 16, and presses the connection portion 3 a of the wiring board 3 to conduct with the connection portion 2 a of the wiring board 2. The operation of the movable protrusion 15 is obtained by pushing the top member 12 from the outside, and thereafter, the movable member 15 is restored to the original position by the elasticity of the side wall 16 of the inverted cup-shaped member 10.

The through holes 4 formed by the spacer boards 5 and 6
Are different from each other, a step 17 is formed between the spacer boards 5 and 6, so that even when the top member 12 is operated in one side, the inclined top member 1
The reference numeral 2 indicates that the step portion 17 serves as a stopper, and the inclination thereof is stopped so that a necessary pressing force can be transmitted to the inverted cup-shaped member 10.

Further, since the top member 12 and the inverted cup-shaped member 10 are formed by fitting the support portion 11 and the hole 13, even if the appearance of the top member 12 is changed,
If only the shape of No. 3 is uniform, all of them will be compatible, and the versatility of the parts will be very large.

The structure of the switch according to the present embodiment is as described above. Therefore, a click feeling can be generated for a general membrane switch. In this embodiment, a board switch is used and a flexible wiring board is used. However, the present invention is not limited to this, and a hard board can be applied. Of course you can.

[0014]

As described above, according to the structure of the switch according to the present invention, a sufficient click feeling can be generated even in a so-called membrane switch, and anxiety in operation is eliminated. In addition, it is possible to freely perform processing in terms of design, and it is possible to respond to the needs of consumers' preference and to give a sense of quality. Further, as the parts, conventional products can be applied, and the assembling work becomes easy, so that the product cost can be reduced.
