Seeing also Fig. 4, it is the object of present invention electrical property state schematic diagram when electrode.As it can be seen, Fig. 4
Profile for the ZZ ' direction of Fig. 3.Contactor control device 13 comprises those first electrodes 20 and those the second electrodes 21, and those are first years old
Electrode pole 20 and those the second electrodes 21 have electrical property state.When object 14 touches contactor control device 13, object 14 and the first electrode
20 and the second part faradism line of forces 22 between electrode 21 are affected by object 14 and reduce generation one touch sensing electric lines of force
23, from Fig. 4 comparison diagram 2, the present invention reduce because of those electrode break 25 those first electrodes 20 with those second
The basic electric capacity of electrode 21, and when making object 14 touch those first electrodes 20 with those second electrodes 21, its faradism line of force
The variable quantity of 22 knows the variable quantity of the faradism line of force 12 between the electrode 10 of technology and electrode 11 more than former times, and promotes contactor control device

The basic electric capacity of electrode 21, and correspondence makes the faradism line of force between those first electrodes 20 and those the second electrodes 21 relatively large
Amplitude variation, and promote the detecting sensitivity of contactor control device.
Accepting above-mentioned, when the first electrode 20 does not comprises electrode break 25, the area of the first electrode 20 is 100%, but,
When the first electrode 20 comprises an electrode break 25, the area of the first electrode 20 is the first electrode not comprising electrode break 25
The 90～95% of the area of 20, the area of electrode break 25 is the 5% of the area of the first electrode 20 not comprising electrode break 25
To 10%.Similarly, the area of the second electrode 21 is the 90～95% of the area of the second electrode 21 not comprising electrode break 25,
The area of electrode break 25 is the 5% to 10% of the area of the second electrode 21 not comprising electrode break 25.If additionally, the first electricity
When pole 20 comprises four electrode break 25, the area of the first electrode 20 is the area of the first electrode 20 not comprising electrode break 25
60～80%, the area of electrode break 25 is the 20% to 40% of the area of the first electrode 20 not comprising electrode break 25.
Accept above-mentioned, comprise four electrode break 25 respectively according to the first electrode 20 and the second electrode 21, and, the first electrode

After touching contactor control device 13, the variable quantity 24 of the faradism line of force is 10%, and the faradism line of force 22 is left 90%, therefore induction power
The variable quantity 24 of line accounts for associative perception and answers electric lines of force 22 for 10/100=10%.But, if the first electrode 20 and the second electrode 21 wrap
During containing those electrode break 25, the variable quantity 24 of the faradism line of force between object 14 and the first electrode 20, it accounts for associative perception should
The ratio of electric lines of force 22 is then promoted to 16.7%, and when i.e. object 14 does not touches contactor control device 13, the faradism line of force 22 is 60% (this
Weight for the faradism line of force 22 compared to the touch control electrode module not comprising electrode break 25), object 14 touches touch-control dress
The variable quantity 24 putting the faradism line of force after 13 is equally 10%, and the faradism line of force 22 is left 50%, therefore the change of the faradism line of force
Change amount 24 accounts for associative perception and answers electric lines of force 22 to be promoted to 10/60=16.7%.In other words, the sense between object 14 and the first electrode 20
Answer that the variable quantity 24 of electric lines of force is fixing to be accounted for associative perception and answer the ratio of electric lines of force 22 to be promoted to 16.7%.Therefore, by electrode break
The setting of 25 and increase the weight of the variable quantity 24 of the faradism line of force, and increase the sensitive of contactor control device 13 detecting touch position
Degree.But, above-mentioned explanation is only a citing of the present invention, and the present invention is not limiting as the design category of touch control electrode module, i.e.
The present invention does not limits the variable quantity 24 of the faradism line of force and accounts for associative perception and answer the weight of electric lines of force 22.
