Abstract
According to the present invention, an assembly and method is provided for preventing beams or switch contacts from overheating due to high power environments. A MEMS switch is packaged so that the beam and switch is surrounded by an inert, low viscosity, dielectric fluid. Utilizing such a construction conductively and convectively dissipates heat generated by resistive heating of the MEMS beam.
