Some tips about push button switch

1.base material of the pin. The base material of the switches push button is brass or phosphor copper (low grade is iron). In order to reduce the contact resistance, the pins are basically silver-plated, which is silver The SO2 gas in the air will oxidize, which directly affects the solder ability and contact resistance of the switch, so the high-quality switches push button must first be controlled in place in terms of the thickness of the silver plating of the base material of the pin and the silver plating process.
2.Storage for push switch button.When storing the push switch button, be careful not to store it in an incomplete state, otherwise the metal shrapnel inside the push switch button may be easily damaged.
3.Welding Button Light Switches.When the button light switches are over-reflow soldered, it is very likely that some non-standard operations will cause rosin and other flux to enter the switch, which will cause some poor contact in the use of button light switches. Therefore, appropriate anti-rust oil can be added at this time, and its purpose is to clean the rosin on the internal contacts of the button light switches to restore the function of the button light switches. It should be careful not to use industrial alcohol for internal cleaning, because industrial alcohol will corrode the metal part of the button light switches, which will cause the button light switches to lose function.
