Design and Features
Candlestick telephones were designed in a great variety of styles with varying features.
Most recognizable, candlesticks featured a base with a vertical cylindrical neck extending upright for up to 10 inches in length. At the top of the stand was mounted a carbon microphone (transmitter) to speak into, and a switchhook extending sideways upon which an ear piece (receiver) was hung. In order to make or answer a telephone call, the user lifted the receiver off the switchhook, thereby activating an internal switch connecting the telephone to the telephone line.
Candlestick telephones required the nearby installation of a subscriber set (subset, ringer box), which housed the ringer to announce incoming calls and the electric circuitry (capacitor, induction coil, signaling generator, connection terminals) to connect the set to the telephone network.
When automatic telephone exchanges were introduced, the base of a candlestick also featured a rotary dial, used for signaling the telephone number of an intended call recipient.

Famous quotes containing the words design and/or features:
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
“It is a tribute to the peculiar horror of contemporary life that it makes the worst features of earlier times—the stupefaction of the masses, the obsessed and driven lives of the bourgeoisie—seem attractive by comparison.”
—Christopher Lasch (b. 1932)
