Abstract
An arc-ablation resistant switch contact and a preparation method thereof is disclosed. The switch contact is a complex having a plurality of layers of layered structure, wherein a first layer is a hydrophobic rubber layer, a second layer is an adhesive layer, a third layer is a sheet metal layer, a fourth layer is an adhesive layer, and a fifth layer is a metal plated layer; wherein, the fifth layer of metal plated layer is formed by dipping a complex of the first layer, the second layer, the third layer and the fourth layer in a chemical plating bath containing refractory metal elements, and depositing on surfaces of the second layer, the third layer and the fourth layer in the complex by a chemical deposition method.
