Tastaturtaster

Tastaturtaster, often referred to as keyboard keys, are the individual buttons found on a computer keyboard used to input characters, symbols, and commands. Each tastaturtaster is typically a small, rectangular or square component with a legend printed on its surface, indicating the character or function it represents. When a tastaturtaster is pressed, it completes an electrical circuit beneath it, sending a corresponding signal to the computer's processor. This signal is then interpreted by the operating system and software applications to display the intended character or execute the desired command.

The layout and design of tastaturtaster vary depending on the language, region, and intended use of the keyboard. Common layouts include QWERTY, AZERTY, and QWERTZ, named after the first six letters on the top row of alphabetic keys. Beyond standard alphanumeric keys, keyboards feature a variety of special tastaturtaster. These include modifier keys such as Shift, Ctrl, and Alt, which alter the function of other keys when pressed simultaneously. Function keys (F1-F12) are also present, offering shortcuts for various program functions. Navigation keys like Arrow keys, Page Up, Page Down, Home, and End, along with the Enter and Spacebar keys, facilitate text editing and cursor movement. The Esc key is often used to cancel operations or exit menus.

The physical construction of tastaturtaster involves a keycap that is pressed and a switch mechanism. Various switch types exist, including membrane, mechanical, and scissor-switch, each offering different tactile feedback, sound, and durability. The legends on tastaturtaster are typically applied through printing, laser etching, or double-shot molding to ensure longevity.
