A circuit breaker and impedance grounding switch having a first electrical terminal, a second electrical terminal, a third electrical terminal, a first vacuum bottle with a pair of contactors therein, a second vacuum bottle with a pair of contactors therein, and a mechanically interlocked linkage being electrically interconnected to the second electrical terminal and being movable between a first stable position and a second stable position. One of the pair of contactors of the first vacuum bottle is connected to the first electrical terminal. One the pair of contractors of the second vacuum bottle is electrically interconnected to the third electrical terminal. The linkage has a temporary position between the first and second stable positions electrically connecting simultaneously the first electrical terminal to the second electrical terminal and a third electrical terminal to the second electrical terminal.
