AN ELECTRICAL CONTACT TIP FOR SWITCHING APPLICATIONS AND AN ELECTRICAL SWITCHING DEVICE

摘要

An electrical contact tip (5) for switching applications. The contact tip (5) comprises a body comprising a first layer (7a) and a second layer (7b). The first layer (7a) is arranged on the second layer (7b) and is adapted to come i n contact with a corresponding contact tip (5) during switching operations. The first layer (7a) and the second layer (7b) consist of Ag-composites comprising one or more elements, compounds or alloys and the hardness of the first layer (7a) is lower than the hardness of the second layer (7b).
