In order to enable further to understand this creation for reaching technology, means and the effect that predetermined purpose is taked, see also following detailed description and accompanying drawing about this creation, believe purpose, feature and the characteristics of this creation, go deep into and concrete understanding when getting one thus, yet because this creation applies for is press-key structure, so can be used on the many kinds of input units, therefore this creation is that embodiment is illustrated with the remote controller, and appended graphic only provide embodiment with reference to and explanation usefulness, be not to be used for this is created in addition limitr.

Seeing also shown in Figure 1ly, is the first embodiment sectional perspective exploded view of this creation, creates the side cutaway view of first embodiment and Fig. 2 is this.The remote controller of this creation mainly includes a housing 10, be provided with in one first button face 11 and one second button face 12, the housing 10 and have an accommodation space, and on the first button face 11 and the second button face 12, be provided with most first key holes 110 and second key hole 120, and these first key hole, 110 relative these second key holes 120 are arranged for asymmetric manner, just arbitrary key hole 110 of the first button face 11 is between two key holes 120 corresponding to the second button face 12, for mutual staggered pattern, as Fig. 2.

In this accommodation space, be provided with one first circuit layer 21, an insulating barrier 22, a second circuit layer 23, this first, second circuit layer the 21, the 22nd is film circuit wafer, all be laid with the majority circuit line on it, and on the inner layer surface of first and

second circuit layer

21,23, be laid with the symmetrical majority first button electric contact 211 and most second button electric contact 231.

This insulating barrier 22 is to be a film circuit wafer, be located between this first circuit layer 21 and the second circuit layer 23, and all be provided with respect to the position of those button electric contacts 211,231 on this insulating barrier 22 and run through circular hole 221, those symmetrical button electric contacts 211,231 can be separated because of the thickness of this insulating barrier 22.

Most elastic components 41 are round aecidioid and can be rubber, can Open Side Down be attached to this first or the outer layer surface of

second circuit layer

21,23 on, and with respect to the position of those button electric contacts 211,231, the inner face top of this elastic component 41 is provided with a projection 42, corresponding to those button electric contact 211 tops, and the top, outside of this elastic component 41 is provided with a button projection 43, outside proper extended this first key hole 110 or second key hole 120, and can print on the end face of this button projection 43 or mint-mark function literal or pattern.

When the user pushes this button projection 43, make the projection 42 of this elastic component 41 push the electric contact 211,231 of this first or second

thin circuits layer

21,23 downwards, the circular hole 221 that runs through that makes electric contact 211,231 can see through this insulating barrier 22 electrically contacts mutually, to reach the purpose that electrically conducts.

Again as shown in Figure 3, be the second embodiment sectional perspective exploded view, and Fig. 4 is a side cutaway view of creating second embodiment for this for this creation.This housing 10 of creating among second embodiment is identical with first embodiment, difference is in second embodiment and is provided with one first circuit layer 51, one second circuit layer 52, one intermediate circuit layer 53, and this first circuit layer 51 and 53 on this intermediate circuit layer are provided with one first insulating barrier 54, and this second circuit layer 52 and 53 on this intermediate circuit layer are provided with one second insulating barrier 55, this first circuit layer 51, be laid with the majority circuit line on second circuit layer 52 and this intermediate circuit layer 53, and on the inner layer surface of first circuit layer 51 and second circuit layer 52, be laid with most first button electric contacts 511 and most second button electric contact 521, and on this intermediate circuit layer 53 with respect to those button electric contacts 511,521 position is provided with most corresponding electric contacts 531.

Because this intermediate circuit layer 53 can be slim hard circuit board, and can be multilayer circuit board, so the button electric contact 511 of this first circuit layer 51 can be symmetrical with the button electric contact 521 of second circuit layer 52, need not be in staggered distribution.

The first button electric contact, 511 places of this first circuit layer 51 of symmetry are provided with and run through circular hole 541 on this first exhausted layer 54, and this first button electric contact 511 can be separated because of the thickness of this first insulating barrier 54 with the corresponding electric contact 531 of intermediate circuit layer 53.

Similarly, the second button electric contact, 521 places of this second circuit layer 52 of symmetry are provided with and run through circular hole 551 on this second exhausted layer 55, and this second button electric contact 521 can be separated because of the thickness of this second insulating barrier 55 with the corresponding electric contact 531 of intermediate circuit layer 53.

Similarly, be provided with most elastic components 61 and be round aecidioid, be equipped on the outer layer surface of this first and second circuit layer 51,52, and be symmetrical in the position of those button electric contacts 511,521, the inner face top of this elastic component 61 is provided with a projection 62, corresponding to those button electric contact 511,521 tops, and a button projection 63 is established at the outer top of this elastic component 61, outside the key hole 110 of proper extended this upper shell 11 or the key hole 120 of lower house 12, and can print on the end face of this button projection 63 or mint-mark function literal or pattern.

When the user pushes this button projection 63, make the projection 62 of this elastic component 61 push downwards this first or those button electric contacts 511,521 of second circuit layer 51,52, what make that those button electric contacts 511,521 can see through this insulating barrier 54,55 runs through the electrically corresponding electric contacts 531 of these intermediate circuit layers 53 of contact of circular hole 541,551, to reach the purpose that electrically conducts.

First embodiment of this creation is because first circuit layer, second circuit layer and insulating barrier all be soft type thin layer, so the two-sided button that sets need stagger mutually, and feasible button that can the false touch another side when pushing a button.And second embodiment of this creation is because of there being a hard intermediate circuit layer, so the two-sided button that sets does not just need to have staggered mutually.

Above-mentioned disclosed graphic, explanation only be the embodiment of this creation, allly is skillful in this technical staff when can doing other all improvement according to above-mentioned explanation, and these change still to belong in this novel protection range and reach in the claim.
