Wide application of membrane switch panel buttons in instruments
2020/12/5 17:04:15
In electronic circuit, the key switch without lock is widely used. Because it does not need to pass a large current, it is usually small in shape and volume, and is often referred to as a touch button or microswitch. Mouse buttons and mobile phone keyboards are typical examples of button switches without locks. Modern electronic equipment and instruments generally have the function of human-computer interaction. Touching the key is one of the main components in the human-computer interaction. The system can determine how to make appropriate response by the information of the user touching the key, including the system status on time, the number of times of touching, the duration of touching and which key is touched.
In the development of human-computer interaction interface, a technology called membrane key has replaced the light touch button in many occasions. According to the user's requirements, multiple metal contacts can be embedded into the thin film panel composed of several layers of film, and the metal wire is generated by printing method, and the metal contact is connected with the external connection terminal through FPC connection belt. The film button has small touch feeling and can realize multiple keys at the same time. It simplifies the machine reduction design of the board at the same time. In addition, it also has a certain waterproof performance, so it is welcomed by many users. However, due to the need to customize the film button, its manufacturing process is complex, resulting in its high cost. At the same time, the mechanical contact has the life limit and other factors, so its application is also limited.
New Tianma electronics is a high-tech company specializing in the design and production of membrane switches, touch panels and flexible circuits. The company has excellent equipment, complete process of production and manufacturing platform and strong professional and technical team.
