Embodiment

With reference to Fig. 1, it shows press-key structure 100 of the present utility model, comprises that a film circuit board 110, a substrate 120, a button cover 130, one pressure and touch assembly 140 and elastic body 150.Film circuit board 110 comprises that a plurality of first signals produce point 111 and one secondary signal and produce point 112.Substrate 120 is located under this film circuit board 110, in order to carry this film circuit board 110.Button lid 130 comprises a body 131, a plurality of protruding part 132 and a major axis 101, and these protruding parts 132 are located on this body 131, and corresponding these first signals produce point 111, and are positioned on this major axis 101.Pressure is touched assembly 140 and is located on this secondary signal generation point 112, and covers 130 center corresponding to this button.When actual assembled, press and touch assembly 140 between these protruding parts 132.Elastic body 150 is located between this button lid 130 and this substrate 120.

With reference to Fig. 2 a, when button lid 130 was not subjected to pressed by external force, this button lid 130 was positioned at a primary importance P1.With reference to Fig. 2 b, when external force F put on the middle position of button lid 130, this button lid 130 was pressed down to a second place P2.At this moment, these protruding parts 132 are pressed and are touched these first signals generation points 111, and this pressure is touched assembly 140 pressures and touched this secondary signal generation point 112, produces a signal of telecommunication whereby.

With reference to Fig. 3, when external force F put on the lateral location of button lid 130, protruding part 132 pressures were touched this first signal generation point 111 and are produced the signal of telecommunication whereby.At this moment, abundant the pressure touched this secondary signal generation point 112 even pressure is touched assembly 140, and the signal of telecommunication still can produce.Therefore, use the utility model, no matter external force F puts on button covers any position of 130, and the signal of user's desire input all can be by certain input, comfort level and convenience when increasing the signal input.

This elastic body 150 is a scissors shape structure, and a restoring force is provided, so that this button covers from this second site reversion to this primary importance.These elastic bodies 150 are located at the top that these first signals produce point 111, and pass film circuit board 110, this substrate 120 of butt and this button lid 130.In embodiment of the present utility model,, therefore omit the action that shows elastic body 150 for the situation that contacts between clearer demonstration protruding part and first signal generation point.

In the above-described embodiments, this pressure is touched the rubber assembly that assembly is a hemisphere (Dome), and these protruding parts also are rubber assembly.Right its do not limit the utility model, and pressure touches assembly and protruding part can also be other shape, or made by other material.

With reference to Fig. 4, it shows the press-key structure 100 ' of the utility model one variation, wherein, this secondary signal produces point 112 and can omit, produce the signal of telecommunication and produce point 111 with first signal merely, in the embodiment of Fig. 4, press the function of touching assembly 140 to be to provide paragraph sense.

With reference to Fig. 5, it shows the press-key structure 100 of another variation of the utility model ", wherein, this secondary signal generation point 112 and this pressure are touched assembly 140 and also can be omitted simultaneously, produce the signal of telecommunication and produce point 111 with secondary signal merely.

Though in embodiment of the present utility model, these elastic bodies 150 are located at the top that these first signals produce point 111, so it does not limit the utility model, and elastic body 150 also can be arranged on other position between this button lid 130 and this substrate 120.

Though the utility model with concrete preferred embodiment openly as above; right its is not in order to limit the utility model; any insider; in not breaking away from spirit and scope of the present utility model; still can do a little change and retouching, therefore protection range of the present utility model is as the criterion when looking claims person of defining.
