Switches having wettable surfaces comprising a material that does not form alloys with a switching fluid, and method of making same

摘要

Disclosed is a switch having first and second mated substrates defining therebetween a number of cavities. A plurality of wettable surfaces is deposited in one or more of the cavities. A switching fluid, held within one or more of the cavities, serves to connect and disconnect at least a pair of the wettable surfaces in response to forces that are applied to the switching fluid. The wettable surfaces are formed at least in part of a material that does not form alloys with the switching fluid.
