4 Types of Keyboard Switches
Keyboards are highly useful for a variety of tasks, from computers, to complicated industrial machines, to keypads for security locks and door closures. There are actually a variety of keyboard switch types, which are ideal for different kinds of circumstances and uses. Some of the most popular forms of keyboard switches include the dome switch, scissor switch, mechanical switch, and the buckling spring keyboard switch. Each type of switch is slightly different and provides different advantages.
Done switch: Dome switches combine the properties of membrane and mechanical switches. A membrane switch basically consists of a small membrane pressed onto a circuit board, which then connects a circuit and performs an action. The dome switch places a small, flexible dome above each key that touches the circuit when pressed. Usually, a dome switch has a membrane over the dome to protect the keypad.
Scissor switch: The scissor switch is a more complicated version of the dome switch. A scissor like joint under the key helps press the key into place when pressed. The scissor switch depresses a rubber dome quickly and efficiently, which makes scissor switch keyboards require less space between keys. This helps keep the keyboard cleaner and free of debris.
Mechanical switch: A mechanical switch is one of the original forms of keyboard switch. In a mechanical switch, each key has its own switch directly under the key. This makes it less likely that the keys will fail, but they are also harder to manufacture. Few modern keyboards use mechanical switches, but some still do.
Buckling spring switch: A buckling spring switch is one of the original forms of keyboard switches as well. Old typewriters often used this switch style. Each key has its own individual hammer, which hits the key and causes the key to engage. This gives each key a satisfying indentation and sound when the key is pressed.
