An ultrafast electromechanical switch having a drive mechanism comprising three non-movable contacts, an actuator and two movable contacts. 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.

Ultrafast electromechanical disconnect switch having contact pressure adjustment and switching chamber

An ultrafast electromechanical switch having a drive mechanism comprising two non-movable contacts connected to electrical feedthroughs, one actuator and one movable contact. 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.

Ultrafast single actuator electromechanical disconnect switch

An ultrafast electromechanical switch having a drive mechanism comprising three non-movable contacts, an actuator and two movable contacts. The switch further including 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.

Ultrafast electromechanical disconnect switch having contact pressure adjustment

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.

Ultrafast electromechanical disconnect switch having elliptical shell surrounded actuator

An ultrafast electrical (e.g., transfer, disconnect, etc.) switch that is simple, compact, does not require high energy to operate, ultralow loss, clean, and capable of being automatically reset. The invention includes a fast electromechanical switch having a drive mechanism integrated into the switching chamber. The integration of the drive mechanism into the switching chamber provides faster contact travel and therefore a faster switching operation. Additionally, the switching chamber is a self-contained environment that may consist of a high-pressure gas or a vacuum. The invention further includes an ultrafast disconnect switch. The invention generally is an integrated piezoelectric-actuator-based mechanical switching mechanism. The mechanism has a central piezoelectric actuator that extends to pull contacts inwards in order to obtain two disconnects within a millisecond or less. Surrounding the piezoelectric actuator is a polymer insulating shell and beyond the shell is the metallic conductor.
