Abstract
A switching device facilitates access, repair, maintenance of the device during operation in a electrical substation, and minimizes real estate and equipment in the electrical substations. The device integrates air disconnect switches, preferably mounted atop each bushing. The device further comprises wheels, a removable rail system, and a staggered height arrangement of the switches on the bushing to allow translation of the device from a first position to an electrically isolated second position.
