A screen is physical divider intended to block an area from view or to block access. Screens often provide protection or even filtration and may have holes or perforations allowing air or liquid flow. A screen may also refer to a "touch screen" which provides a graphical user interface (a display device) which allows the user to interact with a computer or control by touching areas on the screen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electro-mechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching, current can pass between them, while when the contacts are separated no current can flow.
