The failure of Solid silver contacts for electrical refers to the abnormal function of silver contacts due to the increase in contact surface resistance during use. The possible factors are roughly as follows:
Sulfurization
Since silver easily reacts chemically with sulfur, silver sulfide is generated. Assuming that there are rubber bands, crepe paper containing sulfur, label paper containing sulfur, dry tape, rubber pads, rubber tires, sulfur gas, etc. in the use environment, these will cause the Solid Silver Contact Rivet to turn black. At the same time, the sulfidation rate can be increased due to the increase in ambient temperature.
Dust pollution
Air dust will adhere to the outside of the Solid Silver Contact Rivets.
Acid corrosion
Silver contacts for Relay treated with nitric acid leaching and electroplating technology will wash away the outer surface of the silver alloy and expose the metal to the air to form metal oxides. Part of the battery phenomenon: also called a microcell. Many fine short-circuit primary batteries are composed of a thin film of metal (such as carbon or other metal particles) and covered with an electrolyte solution.
Assuming that the base metal is more active than the impurity, the metal dissolves and electrochemical corrosion occurs.
For example, the appearance of a metal machine is exposed to humid air, absorbing carbon dioxide and water vapor in the air and condensing on its appearance, becoming an electrolyte solution, forming part of the battery, causing mechanical corrosion.
Other pollution
Substances such as automobile exhaust, dust, sweat, grease, detergents, polishes, etc., when using carbon dioxide at high temperatures during the use of switches, can also cause the Solid silver contacts for electrical to fail.
