2. (Telephone) An apparatus containing switches by means of
which a connection may be made from an incoming telephone
line to any one of numerous outgoing lines. The switches
may be either mechanical or electronic, and the switching
action may be automatic, controlled by signals in the
incoming call, or manual, controlled by a switchboard
operator. In older style manual switchboards, the circuits
were connected by the use of patchcords, inserted into
plugs.
