   After the heat coils were pulled on the old main frame, the remaining step was merely to pull the wooden plugs on the new switchboard by the strings attached to them (which are bunched together) upon a signal given from the old terminal room, indicating the removal of the heat coils above mentioned. By this means the cut-over was accomplished almost momentarily, the process occupying not over two seconds’ time.
