NPWHF1045 - Telegraph Key
A telegraph key is a specialized electrical switch used by a trained operator to transmit text messages in telegraph systems, usually in Morse Code. Keys are used in all forms of electrical telegraph systems, such as landline or "wire" electrical telegraphy, and "wireless", or radio telegraphy. An operator taps on the switch, connecting and disconnecting the electrical circuit, creating electrical pulses of two different lengths called "dots" and "dashes", to spell out text messages in code.
This example is a Straight Key style of Telegraph key which was used as a spare key by Mrs Millgate of Finke Station.
