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.

An apparatus for an electrical switch that includes a rotor cam having a rotor interface, a handle interface, and a spring arm interface. The rotor interface includes a plurality of side interface features that couple the rotor cam to a rotor of the electrical switch so that rotation of the rotor cam causes rotation of the rotor. The handle interface allows coupling of the rotor cam to a handle, wherein the handle interface is sized so as to allow a predetermined amount of independent rotation of the handle relative to the rotor cam before further rotation of the handle causes rotation of the rotor cam. The spring arm interface couples a spring arm of the electrical switch to the rotor cam so that a bias spring of the spring arm biases the spring arm against the rotor cam. Numerous other embodiments are provided.
