A rotary dial is a component of a telephone or a telephone switchboard that implements a signaling technology in telecommunications known as pulse dialing. It is used when initiating a telephone call to transmit the destination telephone number to a telephone exchange. On the rotary dial, the digits are arranged in a circular layout, with one finger hole in the finger wheel for each digit. For dialing a digit, the wheel is rotated against spring tension with one finger positioned in the corresponding hole, pulling the wheel with the finger to a stop position given by a mechanical barrier, the finger stop. When released at the finger stop, the wheel returns to its home position driven by the spring at a speed regulated by a governor device. During this return rotation, an electrical switch interrupts the direct current DC of the telephone line local loop the specific number of times associated with each digit and thereby generates electrical pulses which the telephone exchange decodes into each dialed digit. Thus, each of the ten digits is encoded in sequences to correspond to the number of pulses; thus, the method is sometimes called decadic dialing. Pulse count dialing is a digital addressing system which uses decimal pulse count modulation. The typical average baud rate is 10 bits per second, though the system will usually except from about 9 through 13 pulses per second, a requirement due to variations in the rotary dial mechanism governor speed. This dialing method is the world's first mass scale digital addressing system. It is sometimes erroneously referred to as an analog system due to some individuals' beliefs that mechanical and old are synonyms for analog. However, like the telegraph, which is also mechanical and digital, and which uses both pulse count and pulse width modulation for communicating, pulse dialing is a digital communication method used for addressing telephone subscribers.
