Trimphone

From Wikipedia, the free encyclopedia

The Trimphone is a British model of telephone designed in the 1960s. It was positioned as a more fashionable alternative to the standard telephones available from the GPO. The name is an acronym standing for Tone Ring Illuminator Model, referring to the then innovative electronic ringer ("warbling", as opposed to the traditional bell) and the illuminated dial. The luminous dial contained the mildly radioactive element tritium, which caused some concern about safety. Although a later model featured buttons that did not light up instead of the original dial, it continued to be known as the Trimphone. Consumers were divided as to its aesthetic merits, and some models require rewiring in order to connect to the PSTN in the UK.
