The computer keyboard is one of the important hardware that helps to control and navigate the computer hardware. The working of the keyboard is through the use of the LED light diode that emits light in the form of the light signal during usage of the keys or the keyboards. To make the computer keyboard more efficient to use, special types of grease and lube are used on it so that they will be easier to replace. Some keypads are built using a special type of rubber feet so that it will be easier to keep them in place when pressed. There are also some special type of switch that is placed over the main board so that when the switches are unplugged, they will not get stuck on any of the terminals of the keyboard.
