Abstract
A keyboard includes a plurality of keys. Each key includes a base, a key cap detachably connected to the base and includes at least two conductors, a flexible element connected between the key cap and the base, and a plurality of conduct lines mounted on the base. The conduct lines are not contacting each other. One end of each conduct line is connected to a processing unit. Each conduct line is assigned a code. If the key cap of one key is pressed, the conductors of the key contacts the conduct lines, thereby creating an electrical connection between the two conduct lines, and generating an electrical signal. The processing unit determines the function of the key according to the codes of the connected conduct lines.
