Abstract
The utility model discloses a touch switch, relating to a switch, which is provided to solve the problem that the present touch switch easily appears the poor contact phenomenon. The utility model comprises a base, a cover board and a button which is arranged inside the cover board and with one end through a through-hole which is on the cover board, wherein the base, the cover board and the button form a cavity which from the top to the bottom is equipped with a dynamic contact reeds and contacts. The contacts are divided into periphery static contacts and central static contacts, wherein the central static contacts are fixedly arranged on the middle portion of the bottom of the base cavity, the periphery static contacts are disposed on the perimeter of the bottom of the cavity, and the perimeter of the dynamic contact reed contacts the periphery static contact. When pushing down the button, the middle portion of the dynamic contact reed is able to contact the central static contact of the center of the cavity bottom, thereby conducting the related circuits. The central static contacts have three to ten. The beneficial effect of the utility model is that the touch switch has a good conducting effect and a high reliability.
Description
Technical field
The utility model relates to a kind of control switch that is installed on communication apparatus, household electrical appliance or the electronic instrument, relates in particular to a kind of touch-switch.
Background technology
In the prior art, communication apparatus, control switch on household electrical appliance or the electronic instrument mostly is some contacts, it is mainly by pedestal, cover plate and be installed in the cover plate and an end passes the button of the through hole on the cover plate, the inside of pedestal forms cavity, be provided with movable contact reed and contact in the cavity from top to bottom successively, the contact is divided into peripheral fixed contact and center fixed contact, the center fixed contact is fixedly installed on the middle part of base bottom surface, peripheral fixed contact is symmetricly set on the periphery of base bottom surface, the periphery of movable contact reed contacts with peripheral fixed contact, when pressing the button, the middle part of movable contact reed can contact with the center fixed contact at cavity bottom center, thereby with the interlock circuit conducting.Therefore this touch-switch is because its movable contact reed is a complete flat member, and the surface of the contact at pedestal cavity bottom center is a plane, when switch connection, contacts for any between movable contact reed and the contact point.In the process of using touch-switch, pumping of button and movable contact reed can have been fanned dust, and makes these dust accumulate in the surface of center fixed contact, at this moment just is easy to cause the touch-switch loose contact.
The utility model content
The purpose of this utility model is to solve the problem that is prone to the loose contact phenomenon that existing touch-switch exists, and a kind of multiple spot contact or line contact touch-switch are provided.
In order to achieve the above object, the utility model adopts following technical proposals:
This utility model includes pedestal, cover plate and be installed in the cover plate and an end passes the button of the through hole on the cover plate, pedestal and cover plate, form cavity between the button, be provided with movable contact reed and contact in the cavity from top to bottom successively, the contact is divided into peripheral fixed contact and center fixed contact, the center fixed contact is fixedly installed on the middle part of base bottom surface, peripheral fixed contact is arranged on the periphery of base bottom surface, the periphery of movable contact reed contacts with peripheral fixed contact, the middle part of movable contact reed is corresponding to the center fixed contact, when pressing the button, the middle part of movable contact reed can contact with the center fixed contact at cavity bottom center, thereby with the interlock circuit conducting; Described center fixed contact is 3 to 10.
Owing to adopted technique scheme, compare with existing touch-switch, the beneficial effects of the utility model are: the increase of center fixed contact makes to form line between movable contact reed and the center fixed contact and contact, strengthen the conducting effect of touch-switch, further improved the reliability of touch-switch.
Description of drawings
Fig. 1 is the cutaway view of the utility model embodiment;
Fig. 2 is the vertical view after the cover plate among Fig. 1, button and elastic conducting strip are removed.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is described in detail.
As shown in Figure 1, this utility model comprises cover plate 1, pedestal 2 and is installed on the button 3 that the interior also end of cover plate passes the through hole on the cover plate; Form a cavity between described pedestal 2 and the cover plate 1, be disposed with contact, movable contact reed 6, dustproof adhesive tape 7 in the cavity from bottom to top, the contact comprises that two are positioned at base bottom surface peripheral fixed contact 4 and three center fixed contacts 5 that are positioned at the base bottom surface center all around; Contact with two peripheral fixed contacts 4 around the movable contact spring 6, the middle part of movable contact reed 6 is corresponding to center fixed contact 5; Dustproof adhesive tape 7 is used for sealed cavity the latter half, prevents that dust from dropping on the surface of center fixed contact.
Described button 3 has bigger inner termination of a diameter and the less external end head of a diameter, and described external end head stretches out and passes the through hole of described cover plate 1 from the bigger inner termination of diameter.The inner termination that the diameter of this button 3 is bigger offsets with movable contact reed 6 across dustproof adhesive tape 7.Described inner termination is a sphere, compares with the inner termination of existing planar structure, and the inner termination of spherical structure is bigger with the contact-making surface of the movable contact reed that is out of shape because of pushing of button.
Fig. 2 is the vertical view after cover plate, button and the elastic conducting strip among Fig. 1 is removed, the peripheral fixed contact 4 that wherein is positioned at the cavity bottom both sides has two, the center fixed contact 5 that is positioned at the cavity bottom center has three, peripheral fixed contact 4 links to each other and draws the first winding stitch 9,10, three center fixed contacts link to each other draw the second winding stitch, 11,12, two winding stitches respectively with relevant circuit connection.Press button 3 downwards, movable contact reed 6 contacts or the line contact with three center fixed contacts formation multiple spots at cavity bottom center, with relevant circuit turn-on.
In the utility model, the center fixed contact can have 3,4,5 or more, and they form line with movable contact reed 6 and contact, and have strengthened the conducting effect of touch-switch, have further improved the reliability of touch-switch.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those skilled in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection of the appended claim of the utility model.
