Q. Illustrate working of rubber dome keyboards?
Rubber Dome: In rubber dome keyboards both positioning and contact are controlled by a puckered sheet of elastomer that is a stretchy rubber-like synthetic material. This sheet is moulded to have a dimple or dome in every keycap. Dome houses a tab of carbon or other conductive material that serves as a contact. When a key is pressed dome presses down to touch other contact and complete circuit. Elastomer then pushes the key back. This is the most popular PC keyboard design because the domes are cheap and proper design can give the keyboards an outstanding feel.
