The SMD touch switch is an electronic component that initially appeared in Japan to apply pressure to the operating direction of the switch under conditions that can meet the operating force. When the relevant pressure is removed, it can be immediately disconnected. Its internal structure is achieved by changing the force on the metal elastic piece; This product consists of inserts, shrapnel, base, buttons, and cover plates. When selecting it, you need to be able to follow the following techniques.
Shopping tip 1: It is necessary to be able to see the silver plating thickness and silver plating process of the pin substrate. When purchasing SMD touch switches, it is necessary to be able to choose from aspects such as protection, solderability, conductivity reliability, lifespan, feel, production process, and installation size. Especially, it is necessary to consider the silver plating thickness and process of the pin substrate. Generally, silver plating thickness above 0.3um is good, followed by thin silver plating thickness above 0.2um, followed by silver plating thickness of 0.1um. Many times, pre nickel plating and silver plating on the substrate are good processes, Next, the substrate is pre coated with copper and then silver, and then the substrate is directly silver plated to see if there is a protective treatment agent on it. If there is no protective agent, not only does it not have waterproof function, but such a switch is easily oxidized.
Purchasing Technique 2: Be able to see the structure of the contact points. After all, patch touch switches rely on contact between contact points and shrapnel to conduct, and only the larger the contact area of the contact points, the better. A better contact surface structure should be a crater type, followed by a slotted type, and then a flat bubble type, which is a 1-point contact type.
