ABSTRACT:
Implementations provide a first option of simultaneously turning on or turning off two distinctly separate and isolated electrical circuits, such as when each of two electrical devices are powered by a different energy source. Implementations provide a second option of connecting the two separate circuits together, such as when both of the first electrical device and the second electrical device are to be powered by both of the different energy sources connected in parallel. Included is an electrically isolative rotor internal to a housing. The rotor is keyed with an external knob used to control rotational position of the rotor. Further included are electrically conductive link bars contained by the rotatable rotor that electrically couple with stationary bus bars dependent upon rotational positioning of the rotor. Other implementations of the enhanced switch are envisioned including another depicted implementation discussed allowing for a double-pole, double-throw switch.
