Description

A kind of electric thin switch

Technical field

The present invention relates to a kind of electric thin switch, especially relate to a kind of electric thin switch that has long button.

Background technology

Thin film switch is made of lead-out wire, upper electrode circuit, lower electrode circuit, intermediate isolating layer and panel layer etc., is used in the electronic products such as office equipment, household electrical appliance more.In some electric thin switches, certain class button can be realized different functions by repeatedly triggering, such as realizing " starting/suspend/stop " three kinds of functions, the triggering each time of thin film switch button is all to signal of control chip, realize three kinds of different functions by the chip controls circuit, just need a key position is marked three kinds of different functions at panel layer, the position that its mark takies is longer relatively, accordingly, the electric thin switch key generally also needs to occupy equal length and form a kind of long button with its mark, can both play the effect of control switch function in the scope of the button of rectificating.

The length of long button is generally more than 20mm, on the separator of thin film switch inside, correspondingly be split into whole oblong aperture, elliptical aperture or circular hole, line button is correspondingly done rectangularity or circle, but easy like this because of the separator perforate excessive, be easy to cause that button operation power is undesirable, even cause circuit to stay causing short circuit making product failure.

Summary of the invention

For avoiding the defective of prior art, the invention provides and a kind ofly can in the scope of long button, play the control switch effect, can satisfy the button operation power of product and the electric thin switch that electric property requires again.

The present invention is achieved in that

A kind of electric thin switch, comprise panel layer, face glue-line, last circuit layer, separator, following circuit layer and primer layer, be pasted together successively between each layer, panel is provided with plurality of keys, wherein has a long button at least, the last circuit layer corresponding with described long button, following circuit layer position are printed with conductive contact respectively, the separator position corresponding with long button is provided with the strip hole, the strip hole is made up of the aperture that is no less than two, aperture intersects in twos and is communicated with, and the formed distance in intersection is the narrowest.

The shape of conductive contact is identical with the shape in described strip hole, and the aperture of forming described strip hole is not less than 5mm in the narrowest distance that intersects connection place.This structure can guarantee on the one hand in any position of long button to push with certain pressure and make upper and lower circuit contact contact, and the narrowest place can effectively separate upper and lower layer of circuit on the other hand, the electric fault of avoiding circuit to stay causing.

Described aperture is a kind of in circular hole, elliptical aperture or the polygonal hole.

Be printed with insulating point on the conductive contact of following circuit by the product failure that short circuit causes for further avoiding circuit to stay causing, the diameter of insulating point is φ 0.5～0.Smm, highly is 20～30 μ m, and distribution density is 1～3 point in every orifice region.

The present invention has solved the defect problem of prior art well, can both play the effect of switch in by key range in panel length, and is easy to operate; Electric thin switch of the present invention has good electric property, can not form short circuit phenomenon, and button operation power satisfies the requirement of product.

Description of drawings

Fig. 1 is the internal structure decomposing schematic representation of electric thin switch of the present invention.

Fig. 2 is the internal structure part section enlarged diagram of the long key position of electric thin switch of the present invention.

Fig. 3～Fig. 6 is the strip hole schematic diagram of different embodiment.

Embodiment

As depicted in figs. 1 and 2, electric thin switch of the present invention includes panel layer 1, face glue-line 2, last circuit layer 3, separator 4, following circuit layer 5 and primer layer 6, is pasted together successively between each layer.

Panel 1 is provided with a plurality of buttons, wherein button 11 is long button, and length is more than the 20mm, and separator 4 is to intersect the strip holes 40 that form by three elliptical apertures 401 with the long button 11 corresponding Position Design of panel 1, distance between the intersection point is not less than 5mm, and the mould punching and shaping is adopted in hole 40.Respectively be printed with the

conductive contact

7 and 8 identical in last circuit layer 3 and following circuit layer 4 and long button 11 corresponding positions, so both widened the contact range of long key switch, meet the requirement of product operation power again with hole 40 shapes.

Be printed with insulating point 9 on the conductive contact 8 of following circuit layer 5, be distributed on the central point in hole 401, the diameter of insulating point 9 is φ 0.5～0.8mm, highly is 20～30 μ m, has further improved the reliability of switch electric property.If the area of long button is excessive, can also on following circuit layer 5, increase the quantity of insulating point, can establish 3 insulating point in each aperture at most.

Fig. 3 is the shape that is intersected the strip hole 40 that forms by circular hole; Fig. 4 is the shape that is intersected the strip hole 40 that forms by elliptical aperture; Fig. 5 is the shape that is intersected the strip hole 40 that forms by polygonal hole; Fig. 6 is the shape that is intersected the strip hole 40 that forms by circular hole and polygonal hole; also exist other hole to intersect and form strip hole 40; can't be exhaustive; no matter intersect in the hole of which kind of shape; the stage casing in formed strip hole 40 all can form the position of narrowing that is connected, thereby all drops into protection scope of the present invention.
