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.

Introduction to Membrane Keys

A membrane key, also known as a metaldome array, is a PET sheet with contacts, including metal shrapnel or domes. It is used as a switch on circuit boards such as PCB and FPC, and plays a crucial role in facilitating the interaction between users and instruments. Compared to traditional silicone keys, membrane keys offer a superior tactile feel and longer lifespan. This indirectly enhances the production efficiency of various types of switches that utilize conductive films.

The contacts on the membrane button are positioned on the conductive parts of the PCB, typically located above the gold fingers on the circuit board. When the button is pressed by an external force, the center point of the contact becomes concave and makes contact with the circuit on the PCB. This forms a complete circuit, allowing the current to pass through and enabling the entire product to function properly.
