ABSTRACT:
In one embodiment, a switch includes first and second mated substrates defining therebetween a number of cavities. A plurality of wettable elements are exposed within one or more of the cavities. A switching fluid is held within one or more of the cavities. The switching fluid serves to connect and disconnect at least a pair of the plurality of wettable elements in response to forces that are applied to the switching fluid. A gas is also held within one or more of the cavities. The gas is provided to react with oxides on or in the cavities. An actuating fluid is held within one or more of the cavities and applies the forces to the switching fluid. Methods of making such a switch are also disclosed.
