Abstract
The utility model discloses a light touch switch, which comprises a base, a switching unit arranged on the base and a cover plate which is used for fixing the switching unit onto the base, wherein the base is provided with a conducting part conducted with an external circuit, the switching unit comprises a reed and a handle, the reed is in an arc shape, a fastening part is arranged between the cover plate and the base, the conducting part comprises insertion pins arranged on the exterior of the base, a static contact sheet arranged inside the base and in electrical contact with the reed, and the static contact sheet is of a conical structure. The utility model aims to provide a light touch switch which can prevent dust without adding an isolating layer, the key point of the technical scheme in that the static contact sheet inside the switch is configured to be conical, and the light touch switch is suitable for all light touch switches requiring dustproof function.
Description
Technical field
The utility model relates to a kind of contactor, and more particularly, it relates to a kind of waterproof light-touch switch.
Background technology
Touch-switch, is again key switch, when use, connects to switching manipulation pressuring direction switching function is closed with the condition that meets operating physical force, and in the time cancelling pressure, switch disconnects, and by metal clips, stressed variation realizes break-make to its internal structure.
Touch-switch comprises binding post, base, reed, cover plate and handle, and inner electrical-contact area is little, and after working long hours, its inside easily accumulates dust and causes reed to follow wire terminal poor electric contact.
At present, dust-proof switch on market (Chinese patent that application number is 201320106452.9 discloses a kind of with dustproof membrane switch), has added barrier film between being characterized under base and cover plate.Although carrying out blocks dust by the barrier film increasing, this water proof switch enters switch inside, but because the volume of water proof switch own is little, when being fitted into water proof switch, the barrier film newly increasing also separately needs to paste when adhesive film prevents its assembling to come off, the method of this increase barrier film has improved assembly difficulty and the cost of water proof switch to a great extent, and barrier film is easy to broken invalid by depressing touch-switch is high-frequency.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of simple Dustproof soft-touch switch.
For achieving the above object, the utility model provides following technical scheme: a kind of touch-switch, comprise base, be arranged on the switch element on base and switch element is fixed to the cover plate on base, described base is provided with the conducting portion with external circuits conducting, described switch element comprises reed, handle, described reed is arch, between described cover plate and base, be provided with fastening part, described conducting portion comprise be arranged on base exterior pin, be in the inner static contact electrically contacting with reed of base, the tapered structure of described static contact.
By adopting technique scheme, described static contact is pyramidal structure, described reed contacts by conical point with static contact, even if there is dust to enter into described touch-switch inside, thereby also can because of reed press down and the acting in conjunction of tapered slope under leave static contact top and reach dustproof effect.
The utility model is further set to: described reed centre is provided with through hole and described handle is provided with the counterbore identical with described shape of through holes with the contact jaw of reed.
By adopting technique scheme, described handle presses down arch reed, make curvedly under described reed to contact with static contact, in the middle of described reed, be provided with through hole, described through hole edge one week electrically contacts with taper static contact, and the electrical-contact area of reed and static contact in the described touch-switch of increase ensures the conductivity of described touch-switch, described handle is provided with the counterbore identical with shape of through holes with the contact jaw of reed presses down in process handle, and handle can be dodged out the conical top of described static contact.
The utility model is further set to: through hole marginal portion bending outside arch-core of described reed.
By adopting technique scheme, the outside bending in through hole edge of described reed, plays similar and effect reinforcement, can share the partial pressure of handle to reed, has increased the reed life-span.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
A kind of touch-switch, comprise base 4, be arranged on the switch element on base 4 and switch element is fixed to the cover plate 2 on base 4, described base 4 is provided with the conducting portion 7 with external circuits conducting, described switch element comprises reed 3, handle 1, described reed 3 is arch, between described cover plate 2 and base 4, be provided with fastening part 8, described conducting portion 7 comprises the pin 5 that is arranged on base 4 outsides, be in the inner static contact 6 electrically contacting with reed 3 of base 4, the tapered structure of described static contact 6, described static contact 6 is pyramidal structure, described pyramidal structure the present embodiment preferably adopts conical structure, described conical structure can make static contact 6 all directions all smoother, described reed 3 contacts by conial vertex with static contact 6, even if there is dust to enter into described touch-switch inside, thereby also can because of reed 3 press down and the acting in conjunction of tapered slope under leave static contact 6 tops and reach dustproof effect.
Described reed 3 centres are provided with through hole 10 and described handle 1 is provided with the counterbore 9 identical with described through hole 10 shapes with the contact jaw of reed 3, described handle 1 presses down arch reed 3, make that described reed 3 times is curved to be contacted with static contact 6, in the middle of described reed 3, be provided with through hole, described through hole edge electrically contacts with taper static contact 6 for one week, the electrical-contact area of reed 3 and static contact 6 in the described touch-switch increasing, ensure the conductivity of described touch-switch, described handle 1 is provided with the counterbore 9 identical with through hole 10 shapes with the contact jaw of reed 3 presses down in process handle 1, handle 1 can be dodged out the conical top of described static contact 6.
Through hole marginal portion bending outside arch-core of described reed 3, the outside bending in through hole edge of described reed 3, plays similar and effect reinforcement, can share the partial pressure of handle 1 to reed 3, has increased by 3 life-spans of reed.
