Abstract
A switch, includes electrical contacts separated by a contact gap, a tubular guide disposed around at least one of the electrical contacts axially movable between an open position retracted from the contact gap and a closed position bridging the contact gap, a blast cylinder disposed radially outward of the tubular guide and defining a compression volume therebetween, the blast cylinder axially movable in coordination with the tubular guide between the open position and the closed position, an isolating ring coupled to a tubular guide end, and a blast cylinder bottom ring coupled to a blast cylinder end, the blast cylinder bottom ring and the isolating ring configured to engage each other to form a gas seal to prevent a gas from exiting the contact gap into the compression volume when the blast cylinder and the tubular guide are moved to the closed position.
