This paper presents the electromagnetic analysis and structural optimization of multi-metal layer bridge of Symmetric Toggle Switch (STS) designed for X-band communication applications. Simulated electrical and electromechanical response of multi-metal layer STS is compared with single layer structure. Proposed fabrication process using surface micromachining and metal electroplating is also presented. The switching element consists of two torsion actuators joined together by connecting levers and a central bridge-transmission line overlap plate. In comparison to a single gold layer STS, the isolation for multilayer (Cr/Au) STS degrades from-45dB to-40dB with an increase of 3-4 volts in pullin voltage.
