Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a thin planar switch.

[0002]

2. Description of the Related Art The applicant has proposed Japanese Utility Model Publication No. 3-41382 as a flat-type push switch. In this proposal, a fitting groove is provided in the center of the upper surface of the plate-shaped main body to insert a pressure-conductive type switch element at a step height, and a hook groove is provided below both sides of the main body, and a side plate and a side plate are provided on both sides. A flat-type push switch is described, wherein a pressure-sensitive plate provided with a hook plate is attached to the main body, and the hook plate is hooked in an opposed hook groove.

[0003]

However, in this proposal, a code switch is used as a switch element, which is sandwiched between a rigid main body and a pressure-sensitive plate to form a switch body. Nevertheless, it has a considerable thickness, and there is a problem that the range of use is limited.

[0004]

According to the present invention, there is provided an insulating member comprising two thin plate-like contact plates having both flexibility and restoring property, and a plurality of insulating rods stretched over a wide parallel interval. A thin flat switch, which is disposed facing the frame body, abuts the support frame body on one outer surface of the contact plate, and the support frame body is provided with a support member positioned parallel to the middle of the insulating rod body; It is intended to solve such a problem.

[0005]

The thin flat switch of the present invention normally has a state in which the two contact plates are separated by an insulating frame therebetween, and the contact plate on which the support frame is not disposed is pressed against the contact plate. When a point or area pressure is applied, one or both contact plates are flexed by the pressing force to make partial contact in proximity to each other, so that electricity is supplied and a switch action is performed. When the pressing is released, each contact plate returns to a normal state due to its restoring property.
When the switch of the present invention is housed in a bag-shaped flexible plastic case or the like for shape-retaining protection and for waterproofing and dust-proofing, the handling becomes simple.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention, in which a metal or a dielectric is deposited on one surface of a metal plate such as a copper plate or a plastic substrate so that flexibility and restorability are improved. Two insulated first contact plates 1 and second contact plates 2 are formed, and the two contact plates 1 and 2 are spaced apart from each other by a large parallel distance between two sides thereof. 3 are arranged facing each other with an insulating frame 3a formed in a thin flat shape made of a plastic plate or the like on which the third contact plate 3 is stretched.
The plane switch 5 is constructed by arranging “a”. The support frame 4a is provided with a support bar 4 positioned parallel to the middle between the insulating rods 3. Also, the members of the flat switch 5 may be adhered and fixed, and when they are housed and covered in a bag-shaped flexible plastic case 7 as shown in FIG. May be. When the coating is performed in this manner, the manufacturing is facilitated and the switch body is also protected, so that the waterproofing and dustproofing are excellent and the handling can be made extremely convenient. 6a and 6b are lead wires connected to each contact plate. In the embodiment, all of the members such as the first contact plate 1 are formed in a rectangular shape having a size of about 6 × 10 cm square, but the size and shape can be freely set.

As shown in FIG. 2, in the planar switch 5 constructed as described above, the first contact plate 1 and the second contact plate 2 are normally separated by the insulating rod 3 of the insulating frame 3a as shown in FIG. When the first contact plate 1 is pressed from this state, FIG.
As shown in FIG. 5 to FIG. 5, one or both contact plates are bent,
Depending on the bent state, the two contact plates 1 and 2 are partially in contact with each other and are energized to act as a switch. Note that FIG.
4 shows a case where a point press (arrow) is applied in the middle between the insulating rods 3, FIG. 4 shows a case where a point press (arrow) is applied on the insulating rod 3, and FIG. (Indicated by arrows (arrows)) indicates the flexing contact state of each contact plate when applied, and in the embodiment, a plurality of insulating rods 3 are stretched with a wide parallel interval therebetween, and a supporting support is provided therebetween. Since the bars 4 are provided so as to be parallel to each other, there is no so-called dead zone on the planar switch 5 where no point is lightly pressed and the switch is not activated. When the pressing is released, the contact plate that has been bent returns to the face shape due to its own restoring property, and returns to the normal position in FIG.

The flat switch 5 is used by placing it on a floor or a table with the support frame 4a side down, or by attaching it to one surface of a wall or an instrument. It is also possible to operate the apparatus by suspending it in the air and pressing it with a finger.

[0010]

[Effect of the Invention] As described above, the present invention can manufacture an ultra-thin planar switch with a simple structure without requiring any mechanical element. It is possible to provide a further enlargement, maintenance is not required, and the cost can be reduced.

The insulating frame sandwiching the contact plate is formed by extending several insulating rods at wide parallel intervals, and the supporting frame to be placed underneath has a supporting rod parallel to the middle between the insulating rods. As a result, the flat switch can be turned on even if any point is lightly pressed, so that a dead zone is not formed.

[0012] Since several insulating members of the insulating frame are provided at a wide parallel interval and the supporting members of the supporting frame are provided in the middle between the insulating members, the switching operation is performed with good sensitivity and without unevenness. Has the effect of doing
