The raw material for the production of membrane switch is a very elastic film (PET polyester film). This material can be printed with different characters to indicate the different buttons of membrane switch. It is waterproof, dustproof, conflict resistant and colorfast. Now it is widely used in household appliances, communication equipment, instrumentation, industrial control and other fields.

　　The printing of membrane switch can be divided into two types: front printing and non printing, which are respectively applied to different materials and types of membrane panel. According to the shape of the membrane switch, it can be divided into two types, plane type and drum type.

　　In our daily life, the most common is the flat film switch. Different colors are used to distinguish the functions and uses of different buttons. Users can choose different film materials and double-sided adhesive tape according to their own needs.

　　Drum membrane switch is a new type of switch, which is more beautiful and useful than plane membrane switch in design. Its manufacturing process is based on the general membrane switch, which is made by a special pressing mold. After the membrane switch is hot pressed, the key part is slightly raised to form a three-dimensional key. The membrane switch of drum surface can accurately locate each key qualitatively, which makes it more convenient for people to identify and makes the operator's touch sensitive. The membrane switch you don't know also enhances the decoration effect of product appearance.
