Abstract
An ultrafast electromechanical switch having a drive mechanism comprising three non-movable contacts, an actuator, two movable contacts and a first and second mounting plate forming an elliptical shell configuration about said actuator. The switch further including a switching chamber to provide a self-contained environment that may consist of a high-pressure gas or a vacuum and one or more precision adjustment screws coupled to the non-movable contacts for adjusting the contact pressure. The provided ultrafast electrical (e.g., transfer, disconnect, etc.) switch is simple, compact, clean, exhibits ultralow loss, does not require high energy to operate and is capable of being automatically reset.
