For instance, if someone were to try calling the number 182, they would first need to press the 100s button, followed by pressing the 10s button eight times and the single units button twice. Now people may think that waiting for a rotary dial to spin back multiple times just to dial a number may be an annoyance, but based on past findings it seems to be infinitely easier to dial 182 using three rotations rather than 11 pushes.

How did dials work?
Early dials worked by direct or forward action. The pulses were generated as the dial turned toward the finger stop position. When the user's hand motion was erratic, it produced wrong numbers.
