Abstract
The present invention is about a kind of push-button switch, mainly comprise at least one reversal film, and at least one briquetting, reversal film includes counter-rotating portion, described counter-rotating portion can stressedly reverse, wherein the surface of counter-rotating portion depression is provided with at least one detent, and described briquetting can be located and is contained in this detent.
Description
[technical field]
The invention relates to a kind of push-button switch that console switch in the various electric equipments uses that can be used as, particularly have reverse function, be vaulted movable contact point assembly.
[background technology]
As existing contact panel and the structure that uses the push-button switch of this contact panel, by the base that has formed fixed contact, have on this base with the opposed dome-shaped reversal film of fixed contact and stick on the sticking tablet that can freely bend on the reversal film and constitute.Above-mentioned sticking tablet sticks on the outside of reversal film, under the usual condition, and by from the decoration panel of electronic equipment or push panel and push sticking tablet, so that bonding with it reversal film counter-rotating and contacting with fixed contact, thereby carry out the switching of contact.
The mode of operation of above-mentioned push-button switch has in the industry cycle been implemented for many years; and in the process of implementing; improvement on the relevant art is also arranged; for example: better push feel when the pressing button switch is operated for the user has; usually can be between aforesaid sticking tablet and reversal film; add a briquetting; this briquetting can make the user when pushing this push-button switch; has good hand feeling; when sticking tablet is subjected to pushing; pressing force conducts to reversal film by briquetting, so reversal film is along with reverse by pressure sensitivity with the contact fixed contact " click is rattled away ".
This mode has been brought the convenience of operation to the user; but also exist some hidden danger simultaneously; when briquetting is subjected to user's pressing force and have the trend of moving to reversal film; because the top of reversal film is domed-face usually; and the part that inverse block contacts with this domed-face is the plane; reversal film and briquetting through regular meeting because this plane causes contact unstable with contacting of domed-face, sometimes even contact can occur and misplace.
Given this, being necessary to design a kind of new push-button switch solves the problems referred to above in fact.
[summary of the invention]
The technical problem to be solved in the present invention is to make push-button switch keep having more stable mode of operation under the prerequisite of excellent handle.
The present invention solves the problems of the technologies described above like this: a kind of push-button switch, mainly comprise at least one reversal film, and at least one briquetting, reversal film includes counter-rotating portion, described counter-rotating portion can stressedly reverse, wherein the surface of counter-rotating portion depression is provided with at least one detent, and described briquetting can be located and is contained in this detent.
Compared with prior art, the present invention has the following advantages: by be concaved with detent on reversal film, briquetting is partly accommodated and is positioned and makes briquetting when being under pressure in the described detent, can remain in the detent, is not easy displacement.

Fig. 2 is the three-dimensional exploded view of push-button switch of the present invention.
Fig. 3 is the three-dimensional exploded view of another angle of push-button switch of the present invention.
Fig. 4 is the profile of push-button switch of the present invention along A-A line among Fig. 1.
[embodiment]
Below, will describe in further detail the present invention in conjunction with the accompanying drawings.
See also Fig. 1 to Fig. 3, push-button switch 1 includes reversal film 10, contact with reversal film push and rounded briquetting 20 and with reversal film 10 mutual bonding sticking tablets 30.
Briquetting 20 is an oblate cylinder, is made by the material of no conductivity such as resin or rubber.
See also Fig. 4, when reversal film 10, briquetting 20 and sticking tablet 30 fit together, the counter-rotating portion 101 of the adhered layer of sticking tablet 30 and reversal film 10 is more firm being bonded together, reversal film 10 is close to each other with sticking tablet 30 in the time of can guaranteeing user's pressing button switch 1, and transposition does not take place.And briquetting 20 is not easy transposition equally owing to be subjected to the positioning action of the detent 102 of reversal film 10.When user's pressing button switch 1, briquetting 20 conducts to pressure on the reversal film 10, the counter-rotating portion 101 of reversal film 10 also is subjected to displacement along pressure direction counter-rotating thereupon, makes contact site 103 contact the whole switching circuit of conducting with fixed contact on the printed circuit board (PCB) at last.
Certainly, in the above-described embodiment, sticking tablet 30 is not necessary element, does not have sticking tablet 30 or sticking tablet 30 not bonding with reversal film 10, this push-button switch 1 can be implemented equally, and concrete execution mode determines according to technical staff and enforcement product characteristics.
Technology contents of the present invention and technical characterstic disclose as above, yet those of ordinary skill in the art still may carry out all replacement and modifications that does not deviate from spirit of the present invention based on teaching of the present invention and announcement.Therefore, protection scope of the present invention should be not limited to the content that execution mode discloses, and comprises various do not deviate from replacement of the present invention and modifications, is the present patent application claim and contains.
