Both tact switches and FPC membrane key switches are key switches
1. Membrane switch is a combination of switch buttons, panel function text, marks, trademarks, transparent windows and display windows, and adopts a multi-layer overall sealing structure, and has friction resistance, waterproof, dustproof, anti-harmful gas, and long service life. long and stable performance.
2. Membrane switches have been widely used in intelligent electronic measuring instruments, medical instruments, computer control, CNC machine tools, electronic weighing instruments, post and telecommunications, copiers, refrigerators, microwave ovens, electric fans, washing machines, electronic game machines and other industrial and household The field of electrical products.
Introduction of key film
Button film, also known as metal dome conductive film.
Metal dome conductive film (Metadomearray), it is a PET sheet containing metal dome (dome), used as a switch on circuit boards such as PCB or FPC, and plays an important tactile type between the user and the instrument. function of the switch. Compared with the traditional silicone keys, the conductive film has a better feel and longer life, and can also indirectly improve the production efficiency of various types of switches using the conductive film.
