Telegraph key is a general term for any switching device used primarily to send Morse code. Similar keys are used for all forms of manual telegraphy, such as in ‘wire’ or electrical telegraph and ‘wireless’ or radio telegraphy.
Types of keys
Since its original inception, the telegraph key's design has developed such that there are now multiple types of keys.
Straight keys
A straight key is the common telegraph key as seen in various movies. It is a simple bar with a knob on top and a contact underneath. When the bar is depressed against spring tension, it forms a circuit and allows electricity to flow. Traditionally, American telegraph keys had flat topped knobs and narrow bars (frequently curved). British telegraph keys had ball shaped knobs and thick bars. This appears to be purely a matter of culture and training, but the users of each are tremendously partisan. Straight keys have been made in numerous variations for over 150years and in numerous countries. They are the subject of an avid community of key collectors. The straight keys used in wire telegraphy also had a shorting bar that closed the electrical circuit when the operator was not actively sending messages. This was to complete the electrical path to the next station so that its sounder would operate, as in the operator receiving a message from the next town. Although occasionally included in later keys for reasons of tradition, the shorting bar is unnecessary for radio telegraphy, except as a convenience when tuning the transmitter.
The Morse code key has undergone considerable development since the first Morse telegraph messages were sent. Watch this fascinating video with many different types of antique and vintage Morse key and keyer included that have been seen down the ages.
Diagrams of the very earliest Morse Correspondent keys are shown, along with a Camelback key - a real vintage Morse key dating from around 1860 as well as an early steel lever key, a vintage British Post Office key and many more. Military Morse keys including the WT8 Amp key from WW2 and the famous Bathtub key used in RAF WW2 bombers. Finally mechanical bugs including the Vibroplex and electronic keys or keys are shown.

1857 - 1886 Oller & Company Swedish Telegraph Key
Here is my Oller & Company Swedish Telegraph Key made in Stockholm. Anton Henric Oller was the Employer of Lars Magnus Ericcson and Lindholm & Wikstrom which are also famous telegraph key makers that learned their craft from Oller. Oller made keys from 1857 - 1886. I'm going to put this one in the middle at around 1868 which would make it right at 150 years old.
