Telegraph key (also known as the Morse key) is a generic term for any switching device used primarily to send Morse code. Similar keys are used for all forms of manual telegraphy. Two common uses include the electrical telegraph over wires which activates a Telegraph sounder and radio telegraphy. Several variants exist.


Telegraph keys were once used in the study of operant conditioning with pigeons. Starting in the 1940s, initiated by B. F. Skinner at Harvard University, the keys were mounted vertically behind a small circular hole about the height of a pigeon's beak in the front wall of an operant conditioning chamber. Electromechanical recording equipment detected the closing of the switch whenever the pigeon pecked the key. Depending on the psychological questions being investigated, keypecks might have resulted in the presentation of food or other stimuli. Modern pigeon response keys are specially made switches but are still called "keys" due to their origins as telegraph keys.
