  • Patent number: 4459448
    Abstract: The switch includes a housing having a translucent sleeve of one color projecting from one end thereof. A translucent pushbutton of a different color is reciprocable in the sleeve against the resistance of a compression spring between an OFF position in which it projects from the sleeve, and an ON position in which it is located entirely within the sleeve. A bulb on the inner end of the pushbutton is disposed to be connected through the spring to a power supply, and when energized illuminates the pushbutton so that when the latter is in its outer or OFF position it emits light of said different color, but when in its inner transmits light comprising a combination of two different colors of the pushbutton and sleeve, respectively. Switch operating cams which project from the pushbutton into the housing have sliding engagement with toggle switch blades, which are mounted to pivot about stationary fulcrums between switch opening and closing positions.
