Many technologies have been employed in the past for transmitting a key press to the computer, as well as for providing a solid feel for the user. The earliest keyboards used "key switches", which used very large keys and had a heavy feel when typing, as well as producing a clicking sound for each key press. Since laptops could not accommodate such large keys, they employed the use of small plungers, usually made of rubber, for the key action. Most modern laptops use a "scissor-switch" design for each key, which uses two plastic pieces in a scissor formation. When the key is pressed, the plastic pieces slide and collapse, registering the key press down to a membrane switch. The feel of the scissor-switch keys have become so popular that some manufacturers are now incorporating it into desktop keyboards or laptop keyboards such as Toshiba Laptop Keyboard , Samsung Laptop Keyboard or Acer Laptop Keyboard .
