Abstract
A proximity micro-electro-mechanical system (MEMS) utilizing a gaseous capacitive gap between two conductive members. The gaseous gap is maintained by insulating structures that prevent the two conductive members from shorting. Once actuated, the gaseous gap allows high-frequency signals to be transmitted between the two conductive members.
