New description: [New technical field] [0001] This creation is about a membrane switch, especially a membrane switch that can enhance the function and accuracy of membrane switching. [Previous Technology] [0002] Thin film switches have been widely used in various electronic products in recent years due to their light size, especially when the membrane switch has a small sound when pressed, and is more suitable for buttons or keyboards of various devices. . [0003] A conventional membrane switch mainly comprises a second film and an insulating film between the two films, and a phase of the phase of the two films is respectively provided with a '-/if-conductor, respectively. A thin boat-type button is arranged above the switch, and there is a certain safety gap between the membrane button and the membrane switch to avoid accidental contact; in an ideal situation, if the user's finger accurately touches the position of the two conductors, The two conductors are brought into contact with each other to facilitate the conduction circuit. However, due to the coverage of the membrane button and the small volume of the conductor, even if the surface of the membrane button is provided with an indication pattern such as an indication point, the user's finger is still It is impossible to apply force to the conductor accurately, and it is often necessary to touch the membrane switch correctly after repeated pressing, which not only wastes time, but also easily causes damage to the membrane button; in addition, the rigidity of the membrane button is weak, if The user has insufficient pressing force and cannot smoothly touch the electric conductor. [0004] Therefore, how to solve the above problems becomes the goal of improvement by the present creator. Form No. Α0101 Page 3 of 16 M408782 [New Content] [0005] One of the aims of the present invention is to provide a membrane switch capable of increasing an effective pressing area to improve accuracy when pressed by a user. [0006] In order to achieve the above object, the present invention provides a membrane switch, comprising: [0007] an insulative housing having a first terminal, a second terminal, and a conductive portion electrically connected to the first portion a terminal is electrically isolated from the second terminal, [0008] a conductive reed that bridges the second terminal; [0009] a push handle disposed on the conductive reed and corresponding to the conductive portion; and [0010] a film disposed on the insulative housing to cover the push handle, the push handle abutting the film to cause the film to bulge to form a pressing area; wherein the push handle forces the conductive when the pressing area is pressed The reed is deformed concavely to contact the conductive portion, so that the second terminal is electrically connected to the first terminal through the conductive portion. [0012] Compared with the prior art, the present invention has the following effects: [0013] According to the present invention, a push handle is disposed above the conductive spring, a film is laid over the push handle, and the push handle abuts the film to make the film The bulge forms a pressing zone, so the present invention uses the push handle to form a distinct three-dimensional pressing area on the surface of the film, without any embossed pressing area at the top surface of the conventional membrane switch, which is not only easy for the user to press, and The effective pressing area has also increased significantly. [0014] According to the present creation, a push handle is provided above the conductive reed, and therefore, the user form number A0101, page 4/16 pages, presses the pressing area of the film, and the force of pressing is naturally removed from the push handle. Passing to the conductive reed, and causing the conductive reed to be deformed to contact the conductive portion, and electrically conductively contacting the conductive portion, thereby electrically guiding the originally electrically isolated first terminal and the second terminal Therefore, by setting a push handle, the pressing accuracy of the creation can be greatly improved. [Embodiment] [0015] The detailed description and technical contents of the present invention will be described below with reference to the drawings, but the drawings are for illustrative purposes only and are not intended to limit the present invention. [0016] Please refer to the first to fourth figures, the present invention provides a membrane switch i, which comprises: an insulative body 10, an electro-acoustic blade push handle 30, . . . . . . . . . 40. [0017] The insulative housing 10 is molded of an insulating material such as plastic. The inside of the insulative housing 1 is provided with a cavity S for providing a first terminal, a second terminal 12 and a conductive portion 13 in a valley. As can be seen from the second figure, the conductive portion 13 is electrically connected to the first terminal 11 to be electrically isolated from the second terminal 12; and, as shown in the fourth figure, the two ends of the first terminal U are respectively protruded from the insulating body. The outer end of the second terminal 12 is similarly extended to the outside of the insulative housing 10 and bent into a second pin 121. In addition, the second terminal 12 is formed with two extending portions 14 for the conductive reeds to be bridged, and a guiding pad 141 is formed on the surface of each extending portion 14 for the conductive reed 20 to straddle the conductive connection. The 141 is used to make the horizontal surface of the conductive reed 2 高于 higher than the first terminal 11 , so that the second terminal 丨 2 cannot directly electrically contact the first terminal 11 . Form No. A0101 Page 5 of 16 M408782 [0018] The conductive reed 20 is made of a conductive metal foil material. In the first figure, the conductive reed 20 is shown as a circle, but its outline and shape are not The conductive reed 20 can be electrically connected to the first terminal 11 and the second terminal 12 as compared with the fifth and sixth figures. That is, the direction parallel to the line 5-5 of the third figure is connected to the two opposite side walls of the cavity S of the insulative housing 10, and in the sixth figure (that is, the line 6-6 parallel to the third figure) The direction is then connected across the pad 141 of the second extension 14 of the second terminal 12. Therefore, the conductive reed 20 initially electrically contacts the second terminal 12 and does not electrically contact the first terminal 11. [0019] The push handle 30 has a flat disc shape to increase the effective area of the press and is advantageous for the thin design. The push handle 30 can be made of an insulating material to protect the finger from electric shock when the user presses the membrane switch 1. The push handle 30 is disposed on the conductive spring 20 and corresponds to the conductive portion 13, and more specifically, the push handle 30 is disposed at a central portion of the conductive spring 20 and corresponds to the position of the conductive portion 13, so that When the user presses the push handle 30, the push handle 30 can directly press down the central portion of the conductive spring 20, and the central portion of the conductive spring 20 is deformed concavely and electrically contacts the conductive portion 13 so that the first portion The two terminals 12 are electrically connected to the first terminal 11 through the conductive portion 13. Therefore, the pressing force can be accurately transmitted to the push handle 30 by the position between the push handle 30 and the conductive portion 13 The conductive portion 13 thereby increasing the accuracy of the pressing. The film 40 is disposed on the insulative housing 10 to cover the push handle 30. The film 40 is a film made of plastic or rubber material, which can effectively isolate external dust to prevent contact failure caused by falling dust. As shown in the third figure, this form number A0101, page 6 / page 16 M408782 is created in that the push handle 30 abuts against the film 40 to cause the film 40 to bulge to form the H zone P 'so the user is above the membrane switch] When viewed, it will be clearly seen that the push handle is raised on the film 40, and a striking-pressing area P' is formed thereby helping the user to find the pressing position more quickly and correctly.
