DBJ 700
Called the Ericofon 700, 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.

The original Ericofon was launched by the L M Ericsson Company in 1954 as a convenient, all-in-one telephone.  It was moulded from ABS, which made the telephone light weight.

Multiple designers were involved in the design of the Ericofon. Its early prototypes (1941-1949) were overseen by designers Ralph Lysell, a pioneer of Swedish industrial design and Hugo Bloomberg, the head of the technical department at Ericsson. The Ericofon project was then passed on to Swedish designer Hans Gosta Thames from 1949 to 1954, who took from Lysell and Bloomberg's earlier prototypes to develop a phone that would be "light and feel comfortable in the hand".
