A switching assembly for interrupting current from an upper terminal to a lower terminal. The switching assembly includes an upper bushing, a lower bushing sealably coupled to the upper bushing, the upper terminal coupled to the upper bushing, at least one lower terminal, and a switching medium positioned within a channel formed within the upper bushing. The lower terminal is electrically coupled to the switching medium. According to some embodiments, one or more of the lower terminals are coupled into one or more lower terminal openings formed within at least one of the upper bushing and the lower bushing. According to some exemplary embodiments, the assembly includes a modular terminal ring positioned between the upper bushing and the lower bushing and sealably coupled to both. The one or more lower terminals are coupled into one or more lower terminal openings formed within a perimeter of the modular terminal ring.
