Contact material, device including contact material, and method of making

摘要

A device for controlling the flow of electric current is provided. The device comprises a first conductor (12); a second conductor (14) switchably coupled to the first conductor (12) to alternate between an electrically connected state with the first conductor (12) and an electrically disconnected state with the first conductor (12). At least one conductor further comprises an electrical contact (40), the electrical contact (40) comprising a solid matrix (42) comprising a plurality of pores (44); and a filler material (46) disposed within at least a portion of the plurality of pores (44). The filler material (46) has a melting point of less than about 575K. A method (50) to make an electrical contact (40) is provided. The method (50) includes the steps of: providing a substrate; providing a plurality of pores (44) on the substrate; and disposing a filler material within at least a portion of the plurality of pores (44). The filler material (46) has a melting point of less than about 575K.
