ABSTRACT:
A switch has a channel plate that defines at least a portion of a number of cavities. A switching fluid is held within one or more of the cavities, and is movable between at least first and second switch states in response to forces that are applied to the switching fluid. A plurality of planar signal conductors extend from edges of the switch to within the one or more cavities holding the switching fluid, and are in wetted contact with the switching fluid. Corners in paths of the planar signal conductors may be limited to greater than 90°, about 135°, or equal to or greater than 135°. In one embodiment, signal path corners are so limited, but the planar signal conductors do not extend to the edges of the switch. In another embodiment, the one or more cavities holding the switching fluid are at least partly defined by a bent switching fluid channel.
