Ericofon, bottom view

The Ericofon is a one-piece plastic telephone created by the Ericsson Company of Sweden and marketed through the second half of the 20th century. It was the first commercially marketed telephone to incorporate the dial and handset into a single unit. Because of its styling and its influence on future telephone design, the Ericofon is considered one of the most significant industrial designs of the 20th century by Phaidon.[1] It is in the collection of the Museum of Modern Art in New York City. In Sweden, the Ericofon is known as the cobra telephone for its resemblance to a coiled snake.[2]


The Ericofon was designed in the late 1940s by a design team including Gösta Thames, Ralph Lysell, and Hugo Blomberg.[3] The two major components of the telephone, the handset and the dial, are combined in a single unit. This one-piece design anticipated the evolution of the typical cordless phone and cell phone by several decades. Serial production began in 1954. Early models were sold only to institutions; in 1956, however, production for the open market began in Europe and Australia.

As the Bell System did not permit the operation of third-party equipment on their network, the Ericofon could only be used by independent telephone companies in the United States. North Electric in Galion, Ohio, manufactured the Ericofon for the North American independent market.


The original phone was produced in two slightly different designs. The earlier version is slightly taller, with the earpiece at nearly a 90-degree angle to the base. A later version has a shorter handle, with the earpiece angled slightly downward. The two versions are referred to as the old case and the new case. The old case was molded in two pieces, while the new case was molded as a single piece. Both versions were initially produced in 18 colors. They used the four-prong plug common in the United States at the time.

A third version, the model 700, was produced beginning in 1976. It is easily distinguished from earlier Ericofons by its squarish design, as well as changes to the handle and plug.


When it was introduced on the U.S. market, the Ericofon was available in 18 colors. However, after transfer of production to North Electric, the number of colors was reduced to eight. A small number of phones with clear and metallic finishes were produced for special promotions. The most popular and widely produced colors were bright red and bright white. Other colors included various pastel shades of blue, green, and pink. The phone was never produced in black.


Most Ericofons had mechanical rotary dials, typical of all phones made in the era. While Ericofons produced by Ericsson used miniature buzzers as ringers, North Electric introduced the electronic "Ericotone" ringer. The Ericotone ringer used a simple, one-transistor oscillator circuit to produce a distinctive "chirping" sound. Colloquially, Ericofons were sometimes referred to as "tweeter" phones. This was one of the earliest uses of a transistor in a telephone; telephones with mechanical bell ringers and rotary dials did not need transistors.


North Electric introduced a touch-tone version of the Ericofon in the United States in 1967. Production of this variant was much lower than that of the rotary-dial Ericofons. A design flaw in the hook switch mechanism would cause the touch-tone version of the phone to come apart if it was set down too forcibly or accidentally dropped and the phone then became unusable. It was almost impossible for the average consumers to restore the hook switch mechanism to correct operating condition if it were so damaged. North Electric ceased production of the Ericofon for North America in 1972.

Ericsson introduced a push-button version of the Ericofon, the model 700, for the company's 100th anniversary in 1976. The model 700 had a squarer design than earlier models. It was not a touch-tone phone. Instead, its electronics generated electrical pulses as its buttons were pressed, simulating the pulses produced by a rotary dial. Ericsson continued to produce rotary-dial Ericofons until about 1980.

Recent production[edit]

Wild and Wolf produces an Ericofon-lookalike called "Scandiphone".[4] The modern touch-tone phone is available in several colors and can be bought from web stores. The switch hook was redesigned to be stable. The keypad of the Scandiphones was not a standard touch-tone arrangement but rather appeared in a circle to mimic a rotary dial. A few other companies made Ericofon lookalikes with a more traditional-appearing keypad with the redesigned switch hook. Some of these lookalike phones may have used actual Ericofon cases purchased from excess stock in their phones.
