(embodiment 1)
Fig. 1 is the sectional view of the panel-switch of embodiments of the present invention 1.In Fig. 1, base material 11 is to be the tympan of 25～200 μ m by the thickness that polyethylene terephthalate or polycarbonate, polyimide etc. constitute.Below this base material 11, the synthetic resin of phenolic aldehyde by having disperseed carbon dust or epoxy, phenoxy group, fluororubber etc., forming the sheet resistance value is the first resistive element layer 12 of 0.5k Ω～30k Ω/unit area.
By having disperseed the synthetic resin of carbon dust, it is 50k Ω～5M Ω/unit area that the second resistive element layer forms the sheet resistance value, and thickness is 1～50 μ m, overlap the first resistive element layer 12 below.Further, in this second resistive element layer 13, the particle diameter of urethanes or glass etc. is that the spherical of 5～100 μ m and particle 14 that particle diameter is different are separated into 10～80 weight % and constitute pressure sensitive conductive sheet 15.
Pressure sensitive conductive sheet 15, after forming the first resistive element layer 12 by serigraphy on the base material 11, the overlapping version of using SUS300～100 meshes thereon forms and has made the second resistive element layer 13 that is dispersed with particle 14 by serigraphy.Substrate 16 is film like of polyethylene terephthalate or polycarbonate etc., or inserts the plate object of the epoxy etc. of paper phenolic aldehyde or glass.Substrate 16 be configured in pressure sensitive conductive sheet 15 below.In addition, on substrate 16, vacate the gap of 0.2mm front and back and be formed with silver or a plurality of fixed contact 17A such as carbon, Copper Foil, 17B.
Between pressure sensitive conductive sheet 15 and substrate 16,, form pad 18 by insulating resins such as polyester or epoxies to surround the mode of fixed contact 17A, 17B.And the second resistive element layer 13 and fixed contact 17A, 17B by in the relative mode in space before and after 10～100 μ m, have constituted panel-switch.
The panel-switch of Gou Chenging is installed in the operating portion of electronic device like this.And,, fixed contact 17A, 17B are connected on the electronic circuit (not shown) of instrument via lead-in wire (not shown) etc.
Sectional view when Fig. 2 is the pressing operation of panel-switch of embodiments of the present invention 1.In Fig. 2, when carrying out pressing operation above to pressure sensitive conductive sheet 15, pressure sensitive conductive sheet 15 is crooked downwards, and the second resistive element layer 13 that is dispersed with the part of big particle 14A of particle diameter or 14B contacts with fixed contact 17A, 17B.And via the second resistive element layer 13 and the first resistive element layer 12, fixed contact 17A and fixed contact 17B are electrically connected.At this moment, the part that contacts with fixed contact 17A, 17B mainly is big particle 14A, the 14B of particle diameter that is dispersed in the second resistive element layer 13.

With respect to this, use the pressing force P2 bigger to push than P1, the part that particle 14C, the 14D that the particle diameter in the second resistive element layer 13 is little disperses is also represented with R4 with the resistance value of fixed contact 17A and fixed contact 17B state of contact.Resistance value R4 is contact resistance r4, r5 and the conductor resistance r6 parallel connection and resistance value R3 addition value afterwards of this part in Fig. 3.Thus, resistance value R4 is the value littler than resistance value R3.
Like this,, utilize the different particle of particle diameter 14 to form the concavo-convex second resistive element layer 13, increase with the contact portion of fixed contact 17A, 17B along with the increase of pressing force.And by add the second resistive element layer 13 that the sheet resistance value is different and the conductor resistance of the first resistive element layer 12 in this contact resistance, resistance value changes in the mode of curve C.In addition, the electrical connection between this fixed contact 17A and the fixed contact 17B or the variation of resistance value are detected by electronic circuit, can carry out the various function operations of instrument.
Even under the situation of carrying out repeatedly as above pressing operation, the change of its resistance value is little.For example shown in Figure 4, even the pressing operation by 1,000,000 times is a curve D by the curve C change, resistance value R3 under pressing force P1 and the difference of R5 are also just before and after the number k Ω.Promptly, form the second concavo-convex resistive element layer 13 by the different particle 14 of particle diameter, contact with fixed contact 17A, 17B corresponding to pressing force, and via sheet resistance the value different second resistive element layer 13 and the first resistive element layer 12, can be electrically connected, therefore the change of the resistance value that causes of repeatable operation is little, can obtain stable resistance change.
In the above description, the sheet resistance value of establishing the first resistive element layer 12 is 0.5k Ω～30k Ω/unit area, and the sheet resistance value of establishing the second resistive element layer 13 is that 50k Ω～5M Ω/unit area illustrates.But, the sheet resistance value of the preferred first resistive element layer 12 is 2k Ω～10k Ω/unit area, and the sheet resistance value of the second resistive element layer 13 is 100k Ω～1M Ω/unit area, in addition, the ratio of the particle 14 that disperses in the second resistive element layer 13 also is preferably 50～70 weight %.
Fig. 5 is the measured drawing of resistance characteristic of the panel-switch of embodiments of the present invention 1.In Fig. 5, under the too little situation of the sheet resistance value of the first resistive element layer 12 and the second resistive element layer 13, diminish at once with mode resistance value under little pressing force of curve E.In addition, under the too big situation of sheet resistance value, with the variation for pressing force of the mode of curve F, it is very little that resistance change becomes.But,, can obtain and the corresponding smooth resistance change of the pressing force as curve C by being made as sheet resistance value as described above.
In addition, because pressure sensitive conductive sheet 15 is on the base material 11 of film like, the first resistive element layer 12 and the 13 overlapping printing of the second resistive element layer form, and therefore can form pressure sensitive conductive sheet 15 with the thickness below the 0.3mm, can seek slimming easily.
