Line Finder SwitchesThe line finderref.22 is another type of non-numerical switch which connects the subscriber line to an idle trunk leading to a selector (or in a small system to a connector). The line finder serves the same purpose as the line switch except that the method of accomplishing the connection is reversed. The line finder is directly associated with a selector (or connector), instead of being associated with the line, and it finds the line which is originating the call. The line finder switch may be of the rotary type having access to 25 or 50 subscriber lines, or it may be of the step-by-step type having access to 100 or 200 subscriber lines which terminate on its bank contacts.
