Abstract

The invention relates to a waterproof and dustproof key, which comprises a PCB, a contact and a film, wherein a response region is positioned on the surface of the PCB, the film is provided with a flexible membrane layer, one end of the contact is adhered to the surface of the response region, the flexible membrane layer covers the other end of the contact, and the film is connected with the PCB in a sealed manner. By adopting the sealed connecting mode of the PCB, an adhesive layer and the film, a sealed region is formed inside the key, and the film is made of a waterproof easy-to-clean material, so that the key can be easily cleaned while resisting water and dust. In addition, an elastic sheet is arranged inside the key, so as to bring better hand feeling to the user, and obtain better sensory feedback on key pressing.

Description

technical field [0001] The invention relates to the field of buttons, in particular to a waterproof and dustproof button. Background technique [0002] Keys are an essential part of many electronic devices at present, such as computer keyboards, laptop soft keyboards, mobile phone keyboards and remote control keyboards. Sweat, accidentally spilled drinks and other reasons cause the internal circuit of the key to be gradually corroded, which has a great impact on the life of the key. [0003] For the above reasons, there is an urgent need for a waterproof and dustproof button. Contents of the invention [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a waterproof and dustproof button, comprising: a PCB board, a contact and a film, the surface of the PCB board is provided with a response area, and the film is provided with a soft film layer. One end of the contact is attached to the surface of the response area, th...
