[0004] However, the above device has the problem that the silver contacts generate heat during the contact process, and the heat generated by the silver contacts is not conducted and dissipated. In a high temperature and humid environment, the silver contacts are prone to oxidation, which will affect the service life of the silver contacts. Utility Model Content

[0017] Preferably, the anti-oxidation mechanism comprises an anti-oxidation layer.
[0018] Furthermore, by coating an anti-oxidation layer on the outer surfaces of the silver contacts between the static contacts and the silver contacts between the moving contacts, and cooperating with a protective cabinet to prevent the silver contacts from oxidizing in a high temperature and humid environment, the silver contacts can be effectively prevented from oxidizing during use, thereby maintaining the good conductive properties of the silver contacts.
[0019] Preferably, the anti-oxidation layer is arranged on the outer surfaces of the silver contacts between the static contacts and the silver contacts between the dynamic contacts.
