An electrical toggle switch with self-contained indicating devices for displaying the operating condition of the switch and the electrical equipment controlled thereby. The switch may be of the single pole double throw type, or the double pole double throw type, operated by a three position toggle lever which actuates a fulcrum mounted conductive bridge. The switch housing incorporates indicating lamps with color coded lenses. A legend plate assembly mounted on the switch includes a readily interchangeable legend plate which indicates switch function whether or not specifically illuminated.
