Electrical switch methods and apparatus

An electrical switch comprising:

• a rotor having a plurality of blades, wherein rotation of the rotor causes the blades of the rotor to rotate between an open position that creates an open circuit path and a closed position that creates a closed circuit path through the switch;
• a rotor cam having a rotor interface, a handle interface and a spring arm interface;
• a spring arm having a bias spring coupled to the spring arm;
• and
• a handle;
• wherein the rotor interface includes a plurality of side interface features that couple the rotor cam to the rotor so that rotation of the rotor cam causes rotation of the rotor,
• wherein the handle interface allows coupling of the rotor cam to the handle and 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,
• wherein the spring arm interface couples the spring arm to the rotor cam so that the spring arm is biased against the rotor cam by the bias spring while the rotor cam rotates the rotor between the open and closed positions,
• wherein the handle interface includes an opening in a surface of the rotor cam along a rotational axis of the rotor cam,
• wherein the rotor interface includes one or more side flanges that interface with corresponding features of the rotor of the electrical switch, and
• wherein the one or more side flanges are facing each other and are oriented substantially perpendicular to the surface of the rotor cam having the opening.

A method of forming an electrical switch comprising:

• wherein the handle interface allows coupling of the rotor cam to the handle and 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;
• and
• wherein the spring arm interface couples the spring arm to the rotor cam so that the spring arm is biased against the rotor cam by the bias spring while the rotor cam rotates the rotor between the open and closed positions;
• coupling the rotor cam to the rotor using the side interface features of the rotor cam;
• coupling the rotor cam to the handle using the handle interface of the rotor cam;

• wherein the rotor interface includes two side flanges that interface with corresponding features of the rotor of the electrical switch, and
• wherein the two side flanges are facing each other and are oriented substantially perpendicular to the surface of the rotor cam having the opening.
