You could use CSS sprites where there is a difference in position of an icon within the button image. For example if the icon or knob is left edged, it could mean ON and if right edged then OFF. Additionally you could add labels ON and OFF, also color such that they are supportive alternative clues of the two states.
Those with color blindness can still determine the states using the position of the knob and it would work intuitive as a real electric switch does. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
