Clicker assembly
Provided by the ASK Keyboard Dictionary
Aka/also known as: keyboard clicker, keyboard solenoid, operator feedback
A clicker assembly was an internal component known for being present in various Model B and some Model F terminal keyboards. It was typically a solenoid, but speaker implications were also known. For IBM's terminal usage, it was used for indicating when the keyboard was enabled by its host terminal/program and in some cases for issuing conditional cues. It's also been theorised that it was also used to enhance audible feedback, in some ways comparable to the sound pollution of a mechanical typewriter.
