A push-button telephone is a telephone that has buttons or keys for dialing a telephone number, in contrast to a rotary dial used in earlier telephones.. Western Electric experimented as early as 1941 with methods of using mechanically activated reeds to produce two tones for each of the ten digits and by the late 1940s such technology was field-tested in a No. 5 Crossbar switching system in ...

The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
The British companies Pye TMC, Marconi-Elliott and GEC developed the digital push-button telephone, based on MOS IC technology, in 1970. It was variously called the "MOS telephone", the "push-button telephone chip", and the "telephone on a chip". It used MOS IC logic, with thousands of MOSFETs on a chip, to convert the keypad input into a pulse ...
