1. An electrical circuit comprising at least four electrical loads and a plurality of control signal lines, first and second ones of the electrical loads being polarized and connected in reverse polarity with each other between two of the control signal lines, a third one of the electrical loads being polarized and connected between one of the two control signal lines and a different one of the control signal lines, and a fourth one of the electrical loads being polarized and connected between the different one of the control signal lines and one of the two control signal lines, the connections between the third and fourth electrical loads to the different one of the control signal lines being of opposite polarity, whereby:
a) one of the first and second electrical loads is independently selectively activated when opposite signals are applied between the two control signal lines; the different control signal line being kept in a floating state;
b) the second electrical load is independently selectively activated when the signals are reversed with the different control signal line remaining in the floating state;
c) the third electrical load is independently selectively activated when opposite signals are applied between the one of the two control signal lines and the different control signal line, the other of the two control signal lines being kept in a floating state; and
d) the fourth electrical load is independently selectively activated when opposite signals are applied to the other of the first and second control signal lines and the different control signal line, the one of the first and second control signal lines being kept in a floating state.
