摘要： A changeover switch for medium voltage switchgear is provided. The changeover switch includes a first terminal body, a second terminal body, and two elongate pole bodies. The two elongate pole bodies are arranged parallel to each other and rotatably arranged with first ends on opposite sides of, and in direct contact with the first terminal body around a rotation axis. The two elongate pole bodies are rotatable between an open position and a closed position. The second ends of the two elongate pole bodies are positioned in direct contact with opposite sides of the second terminal body. The changeover switch further includes one or more springs arranged between the two elongate pole bodies to urge the two elongate pole bodies towards each other.
