What are the applications of capacitive film switches in mobile phones and appliances?

Many people do not know what a membrane switch is, or even if they know something, they believe it is rare in daily life. In fact, the use of capacitive film switches has become closely related to our daily lives, and capacitive film switches have become one of the indispensable applications of smartphones. For the convenience of everyone's understanding and comprehension of membrane switches, today we will take you to learn about smartphones, as they are very common. Smartphones do not have concave and convex buttons, followed by touch buttons, which belong to the category of capacitive film switches.

Capacitive membrane switches should be applied in most household appliances due to their micro switch characteristics, small size, and light weight. Many applications we come into contact with in our daily lives, such as TV buttons, DVD buttons, computer buttons, driver buttons, keyboard buttons, display buttons, lighting buttons, etc.

Generally speaking, capacitive film switches have a wide range of applications, not only meeting the requirements of most capacitive film switch panels, but also satisfying the high transmittance of smooth PC for LCD display windows. Its hardness is higher than the strength and toughness of thermoplastic, with low water absorption, wear resistance, friction resistance, and high dimensional stability. The tensile strength is also very good, far higher than PC and PVC. The reason for the low price is that the surface is not easy to process into matte, so textured PET is expensive and is an ideal material for making capacitive film switch circuits.

Lockless key switches are widely used in electronic circuits. Because it doesn't require a lot of current to pass through. Therefore, its shape and size are usually relatively small, often referred to as touch buttons or micro switches. Mouse buttons and phone keyboards are typical examples of not having a lock button. The human-computer interaction function of modern electronic devices and tools, the touch keys of human-computer interaction devices are a major component of the system that can push light touches through user information, including the system's time of contact status. The appropriate response is determined based on the number of times, the length of time, and which key is touched.
