My father bought a Kirtland Cutter home in 1975, and I remember that the home had push-button light switches. I still think they are neat even though they are hooked to knob and tube wiring. It really was not that long ago (146 years) that Edison invented the light bulb and changed the world. In the early years of electricity and some of the homes on the South Hill, there were not even three-way switches yet, as this required more than two conductors of electricity, which is the minimum needed to turn a light on in one location and then be able to turn it off on the other side of the room.
