What are push button switches used in a keyboard？
Computer keyboards, as an important interface for human-computer interaction, have been constantly improving and innovating. One of the key components of this, the tactile push button switch, is an important element that guarantees the performance and user experience of the keyboard. This article focuses on the application of KANGERLE small tact switches in computer keyboards and their key role in enhancing keyboard functionality and human-computer interaction.Get more news about dongnan switch kw3a,you can vist our website!
A computer keyboard usually consists of a number of keys (keystrokes). Each one represents a character, number, or function. The basic components of a keyboard include tactile push button switches, the circuit board, and the connecting cables. Tactile push button switches can be also called tact switches. They play a vital role in a keyboard, which are responsible for converting keystrokes into electrical signals. When a user presses a key, the tact switch will be triggered. Then it connects to the appropriate circuitry and generates an electrical signal that is sent to the computer. The key is then located by a scanning matrix that encodes the characters or numbers corresponding to the key. Next, it can transmit the signal to the computer’s motherboard, which is then decoded by the keyboard controller and passed on to the operating system or application program. This series of steps allows the user’s keystroke operations to effectively interact with the computer.

What are tactile push button switches?

A tactile push button switch, also known as a tactile switch or tact switch, is an electronic component. It is capable of completing or interrupting a circuit when pressed and released. They are used in a wide variety of electronic devices, with one of the most prominent applications being keyboards. These switches consist of several key components: a housing, a push button, contacts, and terminals. The housing encases the internal components, the push button is the part that the user presses. The contacts are responsible for carrying out the conduction or disconnection of the current.
KANGERLE tact switch KEL-A016 is currently used in Lenovo notebook keyboards, which is favored by customers for its good tactile feedback and sensitive operation. A keyboard with 96 KEL-A016 tact switches, their role is to transmit electrical signals to the computer. In detail, after the user presses these keys and the code is recognized. The computer converts the corresponding code into electrical signals that are transmitted to the computer’s motherboard via the keyboard’s connecting cable. The keyboard controller decodes these electrical signals into data that the computer can understand, such as a character or command. This data is then transmitted to the operating system or application program, which accomplishes the appropriate action, such as displaying the character in a text editor or performing a shortcut key operation. This comes down to effective human-computer interaction.
