Four lower contacts 220) for be illustrated, but should not be limited with this, there is usual knowledge in technical field of the present invention
Person can arbitrarily change number of keys included by the membrane pushbutton structure 2 on demand, and (such as the membrane pushbutton structure 2 only includes
Single group of key, or including 104 groups of keys).
Continue please refer to Fig. 2, Fig. 3 A, Fig. 3 B and Fig. 3 C.Fig. 3 A is that the diaphragm type of the first specific embodiment of the invention is pressed
First action schematic diagram of bond structure.Fig. 3 B is that the second movement of the membrane pushbutton structure of the first specific embodiment of the invention is shown
It is intended to.Fig. 3 C is the third action schematic diagram of the membrane pushbutton structure of the first specific embodiment of the invention, to illustrate this hair
How the bright membrane pushbutton structure 2 triggers the digital signal and the analog signal.
In this present embodiment, being only includes single group of key (i.e. single keycap 280, list with the membrane pushbutton structure 2
It one elastic parts 282, the single sensing area 240, the single upper contact 200, the single location hole 2600 and single connects under this
It is illustrated for putting 220).

The sequence of barrier film 260, the lower film 22 and the substrate 262 from top to bottom storehouse.
As shown in Figure 3A, when the user does not press the keycap 280, which is in a reset position.This
When, since the sensing area 240 is not applied to any external force, therefore the impedance of the sensing area 240 will not change, without
Trigger the analog signal.Also, under this state, due to the barrier of the barrier film 260, the upper contact 200 will not under this
Contact 220 connects, and the membrane pushbutton structure 2 will not trigger the digital signal.
As shown in Figure 3B, when the user applies the external force to the keycap 280, which is pressed down against the elasticity
Component 282, the pressure-sensing film 24 and film 20 on this, and make the elastic parts 282, the pressure-sensing film 24 and this on
Film 20 generates deformation and keeps the upper contact 200 close towards the lower contact 220.At this point, since the sensing area 240 has been applied this
The impedance of external force, the sensing area 240 changes, and can trigger the analog signal of the corresponding current external force.Also, such as
Shown in Fig. 3 B, since the upper contact 200 is not connected with the lower contact 220 yet, so when the membrane pushbutton structure 2 will not trigger
The digital signal.
As shown in Figure 3 C, when the user continues to increase the external force, which is moved downward to a trigger position,
And the elastic parts 282, the pressure-sensing film 24 and film 20 on this are squeezed, and make the elastic parts 282, the pressure-sensing
Film 24 and the generation of film 20 deformation on this, and so that the upper contact 200 is passed through the location hole 2600 and connect the lower contact 220.This
When, since the sensing area 240 is applied the bigger external force, the impedance of the sensing area 240 changes again, and touches
The analog signal (that is, being different from the analog signal in Fig. 3 B) of the corresponding current external force of hair.Also, as shown in Figure 3 C,
Since the upper contact 200 and the lower contact 220 directly connect, so when the membrane pushbutton structure 2 trigger the digital signal.
Membrane pushbutton structure of the invention and the exportable digital signal of thin film type keyboard and corresponding user's pressing keys
The analog signal of strength, and there is more preferably practicability.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
