switch
On a system board, switches control various circuits or functions in your system. These switches are known as DIP switches; they are normally packaged in
groups of two or more switches in a plastic case. Two common DIP switches are used on system boards: slide switches and rocker switches. The names of the
switches are based on how the settings (on and off) of the switches are changed.
