Abstract:
A MEMS switch comprising:a substrate member; first and second spaced-apart conductors deposited on said substrate; a plurality of support members; a bridge structure disposed above said substrate and having a plurality of flexible arms connected to respective ones of said support members; said bridge structure including a central stiffener portion; at least one control electrode deposited on said substrate for receiving a DC control signal to activate said switch to a closed position; said bridge structure having an undersurface including at least one metallic area for forming an opposed electrode portion facing said control electrode, for electrostatic attraction upon application of said DC control signal to said control electrode; said bridge structure, upon said application of said DC control signal, being drawn down, by said electrostatic attraction, to complete an electrical circuit between said first and second conductors; and said central stiffener portion being of a material to resist bending in a manner that, when said bridge structure is drawn down completing said electrical circuit, there is no contact between said control electrode and said opposed electrode portion.
