Recently I bought A “Touch Lamp.” If, like me, you are unaware of what is a “Touch Lamp” please allow me to explain that merely touching the lamp on any part of it results in a dim light. A second touch results in a brighter light and a third touch results in the brightest light. A fourth touch extinguishes the light. How does it work? ---
