The top conductive part 221 will not contact the bottom conductive part 211, therefore the top conductive part 221 will not generate electricity with the bottom conductive part 211
Connection.
Refering to Fig. 3,5, and when user presses the press unit 3, it can first overcome the elastic force of the elastomer 42 and interlock
First pushing and pressing part 423 of the elastomer 42 is made to contact second compression zone 523 of the elastic component 52, and then user is allowed to experience
To the resistance of first stage, therefore in this process, user can experience the pressing touch of first segment.
Refering to Fig. 3,6, when user continues to press the press unit 3, and the elastic force of the elastic component 52 is overcome and interlocking makes
Second pushing and pressing part 524 of the elastic component 52 pushes against the top layer 22 through second perforation 511, and makes the top conductive part 221
When contacting and being electrically connected the bottom conductive part 211, user experiences the resistance of second stage at this time, in this process, uses
Person can experience the pressing touch of second segment.
And when user no longer presses the press unit 3, which can be subject to the elastic component 52 and the elasticity
The elastic force of body 42 and reply initial position.
In this way, just can according to the top conductive part 221 and the bottom conductive part 211 be electrically connected situation judge button whether by
It presses.
Since the base portion 521, second elastic ring are made around portion 522 and second compression zone 523 of metal material, and
First elastic ring is made around portion 421 and first compression zone 422 of flexible plastic material, therefore user is in the process of pressing
In, the sense of touch of first segment can be more soft compared to the sense of touch of second segment, and first soft sense of touch variation order firm again is with regard to that can carry
Supply the more comfortable press sense of user.
In conclusion by setting the elastomer 42 and being spaced the elastic component 52 of the elastomer 42 setting, user is allowed to exist
There can be the sense of touch of two-part during pressing, and then promote the comfort level of user's pressing, so the utility model can be reached really
Purpose.
As described above, be only the utility model embodiment, when cannot be limited with this utility model implementation
Scope, i.e., all simple equivalent changes and modificationss made according to the utility model claims book and description, all still belongs to
The scope of the utility model.
