You'd think a piece of plastic generally found on
walls would not figure in the top all inventions. But switches go beyond a fan
of light button, they are implemented at micro levels on electronic systems to
control multiple parallel circuits.
The keyboard would be an array of switches that inputs a certain letter when the button is pressed. Switches are extensively used in electrical systems and huge machinery where control systems need to be in place for its functioning. Magnetic, push button, slide, rotary, toggle switches are a few types. In electronic systems the circuits use relays and transistors to implement switching. Several techniques of communication in electronics like time, frequency, phase multiplexing require switching. Switches offer control mechanisms and their use in any kind of an electronic system cannot be understand.
